From: Nitin A Kamble <nitin.a.kamble at intel.com>
The starting-point code that subsequent patches will modify. This is
a straight copy of the code in the emgd 1.14 emgd driver, specifically
IEMGD_HEAD_Linux/common/drm/emgd_drm.tgz from
LIN_IEMGD_1_14_GOLD_2443.tgz, the 'Linux Tar Ball' release downloaded
from http://edc.intel.com/Software/Downloads/EMGD/.

+ * CONFIG_FOO added here must also have an entry in config_helper.c.
+ * CONFIG_ENABLE_FOO: Should be defined always and defined to a 1 or 0.
+ * This is suitble for use in if(CONFIG_ENABLE_FOO) and expected that
+ * a compiler will optimize away if(0)'s.
+ * CONFIG_LIMIT_FOO: Should prevent some default set of FOO defines
+ * from being included. For instance CONFIG_LIMIT_MODES prevents the
+ * long default list of default modes from being used and instead the
+ * platform's config.h must define the requested modes manually.

+ *
+ * 2) The IAL is requesting a very common "required" mode even though the
+ * port doesn't support it. In this case it should be in the static common
+ * modes table and can be centered in the next larger timings in the
+ * mode table.
+ *
+ * If the Frambuffer is smaller than the timings requested a fake set of
+ * centered timings is returned to program the pipe.
+ *
+ * In the case of VGA modes. If the mode is in the mode table everything is
+ * fine and we just return that. If it is not in the table we find the next
+ * larger suitable mode and prepare to center in that mode. Using the static
+ * timings from the VGA table as the VGA mode. We do not need to generate
+ * a fake set of timings because VGA will center itself automatically in
+ * hardware.
+ *
+ * In the case of LVDS both centering and scaling can happen. If the mode
+ * is in the list it will be scaled to the Native Timings. If the mode
+ * is not in the list (common or VGA) it will be centered in the next larger
+ * supported mode and then scaled to the native timings.
+ *
+ * Centering is always indicated by returning the timings that should be
+ * programmed to the pipe. The timings will then have their extension pointer
+ * set to point to the centered timings. For centering with scaling the
+ * first extension pointer will contain the scalable timings and the
+ * second will contain the centering timings. The static "scaled_timings"

+ * The following macros provide part of the "protected" interface to support
+ * mode-module "requests" for VBlank interrupts.
+ *
+ * Requests are for a "who" and "what." The "who" is what type of code is
+ * making the request, and the "what" is the port that the requestor wants to
+ * know about VBlanks for. Here is additional information:
+ *
+ * - Who - which software is asking:
+ * - WAIT - The code that implements the wait_vblank() function pointer.
+ * When interrupts are requested for WAIT, the interrupt handler
+ * makes note of when VBlanks occur. The WAIT code queries (polls)
+ * whether a VBlank has occured since its request.
+ * - FLIP - The code that implements the {check|set}_flip_pending() function
+ * pointers. When interrupts are requested for FLIP, the interrupt
+ * handler makes note of when VBlanks occur. The FLIP code queries
+ * (polls) whether a VBlank has occured since its request.
+ * - CB - The non-HAL code that registers a VBlank interrupt "callback"
+ * (CB). When interrupts are requested for CB, the interrupt
+ * handler calls the callback when VBlanks occur.
+ *
+ * - What - which port (Note: space is reserve for 4 ports, even only two exist
+ * at this time):
+ * - PORT2 (Port 2, Pipe A, SDVO-B)
+ * - PORT4 (Port 4, Pipe B, Int-LVDS)
+ *
+ * Note: internally, the requests are stored in bits within an unsigned long.
+ * This helps explain the way the macros are implemented:

+ * Description:
+ * Bitbash to read GPIO pins are done on LPC device 0:31:0. So do not
+ * use EMGD_READ32 and EMGD_WRITE32 macros for read/write to device 31. These
+ * macros do mmio only on device2.
+ * To properly read/write mmio on device 31, use
+ * READ_MMIO_REG_TNC(port_type, reg) and
+ * WRITE_MMIO_REG_TNC(port_type, reg, data).
+ * These macros properly set to work for all OSes including VBIOS, but
+ * generate more code compared to EMGD_READ32 and EMGD_WRITE32. So use as
+ * necessary.

+ * configure_display() (micro_mode.c), which is only called by
+ * igd_alter_displays() (micro_mode.c).
+ *
+ * [ ] Implemented proposal: set the value. Correct approach?
+ *
+ * - full_mode_init() (in "igd_mode.c", called by mode_init(); lives in
+ * "micro_mode.c", which is called by init_modules()) uses the quickboot &
+ * qb_* params. The values are stored in a global variable: mode_context->*.
+ * Here's what I learned in terms of what is used (same is true for IEGD
+ * source):
+ *
+ * - The mode_context->quickboot value is only set (here) and is never used.
+ *
+ * - mode_context->seamless (corresponding to params->qb_seamless) is
+ * used in full_mode_init() (igd_mode.c) to decide whether (if TRUE) to
+ * call get_fw_info(), which may set it to FALSE depending on whether
+ * there is firmware info that should affect it. It is also read by
+ * configure_display() (micro_mode.c), which is only called by
+ * igd_alter_displays() (micro_mode.c). It is also read & used to decide
+ * something by igd_alter_displays() (micro_mode.c).
+ *
+ * - mode_context->video_input (corresponding to params->qb_video_input) is
+ * only set (here) and is never used.
+ *
+ * - mode_context->splash (corresponding to params->qb_splash) is only set
+ * (here) and is never used.
+ *
+ * [ ] New Proposal: potentially set the values and do nothing else. Is this
+ * the correct approach?
+ *
+ * [-] Old Proposal: set the values, and if seamless is TRUE, call
+ * get_fw_info(). Can't actually do so, as get_fw_info() is a static
+ * procedure.
+ *
+ * - dsp_init() (in "dsp.c", called by mode_init(); lives in "micro_mode.c",
+ * which is called by init_modules()) uses the display_flags, display_params
+ * & port_order params. It also calls full_dsp_init() and the
+ * device-specific init procedures, neither of which uses any params. Within
+ * display_params, there are several params looked at: port_number,
+ * present_params, ddc_gpio, ddc_speed, ddc_dab, i2c_gpio, i2c_speed,
+ * i2c_dab, fp_info, dtd_list, and attr_list. Right now, none of these are
+ * set.
+ *
+ * - Notes: Here's what I learned in terms of what is used:
+ *
+ * - params->display_flags is stored in dsp_context->display_flags. The
+ * value is used by dsp_dc_init() (dsp.c, called by igd_query_dc() and
+ * mode_init()--called after dsp_init()) to determine if
+ * IGD_DISPLAY_DETECT is set (used frequently in that procedure). The
+ * value is used by igd_query_dc() (dsp.c, called by igd_query_dc() and
+ * mode_init()--called after dsp_init())--after calling dsp_dc_init()
+ * once, if there's only 1 DC, it uses this value to determine if
+ * IGD_DISPLAY_DETECT is set, and if so the bit is immediately turned off
+ * and dsp_dc_init() is called again.
+ *
+ * - params->port_order is used as a parameter to do_port_order() (in
+ * "dsp.c"), which is only called this once via dsp_init(). Based on
+ * this, it seems that we should try to figure out how to re-init this
+ * code. Correct approach?
+ *
+ * - params->display_params is iterated over ... OUCH! display_params IS A
+ * STRUCT OF TYPE igd_param_attr_list_t, AND SOME OF ITS MEMBERS HAVE
+ * POINTERS WITHIN THEM (i.e. HARDER TO GET ACROSS THE IOCTL BOUNDARY).
+ *
+ * Based on the above, it seems that the idea of
+ * re-initializing the DSP module seems like the correct approach. I'm
+ * not quite sure how to do that, but it seems like the right direction
+ * to both keep the HAL code unmodified, and do the user/kernel-space
+ * split.
+ *
+ * [X] Implemented proposal: copy all user-space memory to kernel-space,
+ * and later free any temporarily allocated memory.
+ * [ ] Proposal: re-initialize the DSP module. Correct approach?
+ *
+ * - OVERLAY_INIT() translates to _overlay_init() (in "micro_ovl.c") takes
+ * params as a parameter, which it passes to ovl_full_init() (in
+ * "igd_ovl.c"). If the IGD_DISPLAY_FB_BLEND_OVL bit in "display_flags" is
+ * set, it sets ovl_context->fb_blend_ovl to 1. This flag is used in the
+ * following procedures:
+ *
+ * - ovl_send_instr_plb() (in "emgd_drm/video/overlay/plb/ovl_plb.c") is
+ * called by alter_ovl_plb(), which is called through the ovl_dispatch_plb
+ * table (of type ovl_dispatch_t).
+ *
+ * - ovl2_send_instr_plb() (in "emgd_drm/video/overlay/plb/ovl2_plb.c") is
+ * called by alter_ovl2_plb(), which is called through the ovl_dispatch_plb
+ * table (of type ovl_dispatch_t).
+ *
+ * - ovl_send_instr_tnc() (in "emgd_drm/video/overlay/tnc/ovl_tnc.c") is
+ * called by alter_ovl_tnc(), which is called through the ovl_dispatch_tnc
+ * table (of type ovl_dispatch_t).
+ *
+ * [ ] Implemented proposal: If the IGD_DISPLAY_FB_BLEND_OVL bit in
+ * "display_flags" is set, set ovl_context->fb_blend_ovl to 1. Correct
+ * approach?
+ *
+ * - pi_pd_init() (in the file "emgd_drm/display/pi/cmd/pi.c") accesses
+ * params->display_params. It is called by pi_pd_register() ("pi.c"), which
+ * is called by both igd_pd_register() (in "igd_pi.c") and pd_register() (in
+ * "emgd_drm/display/pd/pd.c"). igd_pd_register() is called by
+ * load_port_drivers() (in "emgd_drv/emgd_dpdloader.c") which is no longer
+ * called (was called during PreInit()).
+ * pd_register() is called by lvds_init() and sdvo_init(), both of which are
+ * called by pi_init_all(), which is not being called.
+ *
+ * [ ] TODO - LEARN ABOUT HOW THE STATICALLY-LOADED PORT DRIVERS WILL GET
+ * THEIR params INFO, AND WHEN THEY WILL WANT IT (i.e. IN RELATION TO X
+ * DRIVER PreInit())
+ *
+ * None of the other modules use and/or need any params at this point:
+ *
+ * - REG_INIT translates to _reg_init() and uses preserve_reg. It's too late
+ * to undo what we chose at kernel init time.
+ * - gmm_init() ignores page_request and max_fb_size.
+ * - CMD_INIT() translates to 0 (i.e. Koheo doesn't use this module).
+ * - pi_init() (in "pi.c", called by mode_init(); lives in "micro_mode.c",
+ * which is called by init_modules()) uses no params.
+ * - APPCONTEXT_INIT() translates to appcontext_init() doesn't use any params
+ * - PWR_INIT() translates to _pwr_init() (in "igd_pwr.c") doesn't look a any
+ * params in context, nor does pwr_init_plb() (in "pwr_plb.c").
+ * - RESET_INIT() translates to _reset_init() IS MISSING. IS IT NEEDED???
+ * Just in case, I looked at the IEGD version (in "igd_reset.c"), which
+ * doesn't look at any params.
+ * - OS_INIT_INTERRUPT() doesn't translate into anything real (i.e. IT IS
+ * MISSING). IS IT NEEDED??? Just in case, I looked at the IEGD version (in
+ * "oal/xfree86/src/interrupt/interrupt.c"), and it is a no-op.
+ * - BLEND_INIT() translates to 0 (i.e. Koheo doesn't use this module).
+ * - INIT_2D() translates to 0 (i.e. Koheo doesn't use this module).

+/*
+ * This is a basic EDID parser. It only parses the parts of the EDID that
+ * are useful for developing timings and identifying the monitor. Items
+ * like monitor serial numbers, chromaticity settings etc. are not useful
+ * in the display drivers. There should be a simple interface to provide
+ * the complete unparsed EDID to IAL, so that such information can be
+ * used by a IAL driver if need be.
+ *
+ * timings_t: This is a structure that contains one set of display timings.
+ * It is complete in that it contains all 12 timings fields instead of
+ * the popular 8. Some of the "Established" EDID timings require all 12
+ * fields. It also allows for both established flags and driver specific
+ * flags to make it flexible enough to work for most drivers. The
+ * EDID parser will mark the flags with FB_TIMINGS_PREFERRED if they are
+ * found to be listed in the EDID. This does not include modes within
+ * the the sync ranges (if provided), only "Established" "Standard" and
+ * "Detailed" timings.
+ *
+ * edid_t: This structure will be populated by the EDID parser. There
+ * are three important areas of information that impact display timings.
+ * The h_max,h_min,v_max,v_min represent the range of timings that the
+ * display is capable of accepting. No timings outside this range should
+ * be used by the driver if a range is provided.
+ *
+ * Any "Detailed" timings will be fully parsed and returned in
+ * the timings array (only the first 12 are parsed, it is very unlikely
+ * that any EDID exist that contain this many).
+ *
+ * Suggested driver behavior when setting display timings would be to
+ * first attempt to use "Detailed" timings provided by the monitor. Then
+ * attempt to use the "Standard" timings that were marked as PREFERRED,
+ * then as a last alternative, use a nonstandard set of timings within
+ * the provided range.

+/* Following is the abstraction of port driver. Port driver passes this
+ * driver information to display driver as part of registering itself with
+ * display driver. pd_register(pd_driver_t *) is called from port driver
+ * in its init function which is called whenever port driver is loaded.
+ *
+ * Port driver provides following list of functions to display driver.
+ * Display driver calls these functions to do the required operations.
+ *
+ * type - supporting display type for the port driver
+ *
+ * flags - flags for the driver. And cannot be changed at runtime.
+ * Once these flags are passed to main driver, they will be
+ * used while setting the mode.
+ *
+ * context - Driver's contextual information. The driver can save
+ * all needed state information in this opaque pointer
+ * such that the driver is entirely reentrant. No writeable
+ * data may be saved in any non-stack variables by a driver
+ * therefore all necessary data must be saved in a private
+ * structure and stored in this pointer. This pointer is
+ * passed to the driver with each function call.
+ *
+ * validate - Display driver calls this function to validate the port
+ * driver by passing a magic cookie. Port driver does some
+ * magic operation and returns another cookie back to caller.
+ * If the returned cookie has correct value then the driver
+ * passes the validation, otherwise driver cannot communicate
+ * with display driver.
+ *
+ * open - This function is to detect for any port device (codec).
+ * pd_callback_t has all the required callback functions
+ * to do this operation.
+ *
+ * init_device - This function detects and initializes any display devices
+ * attached to the codec.
+ *
+ * For ex: a multi function encoder can support a FlatPanel or
+ * TVout display. It has to detect and check for any
+ * Flatpanel or TVout display device attached, then it
+ * initializes the display devices.
+ *
+ * pd_close - closes the display device and frees any memory allocated.
+ *
+ * set_mode - sets/tests a mode. Display (or main) driver calls this
+ * function to set a mode when the encoder in D3 power state.
+ * At this time, DVO timings are off.
+ * If encoder wants to run setmode in any other power state,
+ * then first thing it needs to do is enter into that power
+ * state and then do setmode.
+ *
+ * When this function returns it is expected that:
+ * 1. Either encoder is in D0 power state or
+ * it defers until post_set_mode().
+ * 2. In case of external encoder (example: TVOut encoder)
+ * driving the reference clock, the clock is running.
+ *
+ * post_set_mode- This is called after GMCH DVO timings are on.
+ * This function can be null if there is nothing to do.
+ * This is used to do any post processing on the encoder
+ * after GMCH starts driving the timings. When this function
+ * returns it is expected that the encoder is in D0 power state.
+ * Parameters:
+ * context - port driver context
+ * mode - current timing
+ * flags - not used (for future use).
+ *
+ * set_attrs - to set provided list of attributes.
+ *
+ * get_attrs - to get list of attributes.
+ *
+ * get_timing_list - returns the list of supported modes for the current
+ * attributes. For example if the TVFormat is NTSC, this
+ * function will return only the modes supported for NTSC.
+ *
+ * set_power - to set the power state of the display device.
+ *
+ * get_power - to get the current power state of the display device.
+ *
+ * pd_save - to save the current state of the registers.
+ * - returns the current state in the double pointer 'state'.
+ *
+ * pd_restore - to restore to the passed state. This functions frees the
+ * resources allocated that state.
+ * - pass the previously saved state in 'state'.
+ *
+ * If PD_NO_RESTORE_FREE_STATE is set, then it just frees
+ * the resources without restoring the state.
+ *
+ * pd_get_port_status - to get the status of port/display
+ *
+ *
+ * All functions return value:
+ * == 0 - if success
+ * != 0 - if failure

+ /* OPTIMIZATION CODE BEGINS FOR THE ABOVE SWITCH
+ *----------------------------------------------
+ * Step 1: First identify the code common to all case blocks.
+ * This we call it "common code block" Since this is to be
+ * executed by all the case blocks.
+ *
+ * Step 2: Group the cases into blocks based on how we can combine them
+ *
+ * Eg: case 0: ptr->x = 1; break; // similar code
+ * case 1: ptr->y = 1; break; // similar code
+ * ------Combined block ----
+ * case 0:
+ * case 1: PTR_OFFSET_TYPE(ptr, table[i].offset) = 1; break;
+ * This is an important step because we save code space by
+ * mapping many cases to smaller number of blocks. In the above
+ * we use index to get the right offset of the ptr.
+ *
+ * Step 3: Assign block IDs to each block. Put the case ID, block ID
+ * and other information such as offsets of ptr in a global
+ * table.
+ *
+ * Step 4: During run-time , search through the global table, find the
+ * matching case ID, and execute the common code. Next get the
+ * block ID and execute the block specific code. For the index,
+ * retrieve it from the table for the corresponding case ID.
+ *
+ * Step 5: If no matching case ID is found, error it out.
+ *
+ * Let's look at the optimization code for the above switch.
+ * The code below searches for the list->id in a global table where
+ * we store all the case values along with block numbers and other
+ * information. After we find a valid id in the table , we execute the
+ * common code for all cases first and then we retrieve the block id.
+ * The block id is necesary to determine which block does the id belong
+ * to. This is used to execute block specific code. Similar to switch
+ * cases ONLY here we try to minimize the no of blocks.
+ *

+ /* OPTIMIZATION CODE BEGINS FOR THE ABOVE SWITCH
+ *----------------------------------------------
+ * Step 1: First identify the code common to all case blocks.
+ * This we call it "common code block" Since this is to be
+ * executed by all the case blocks.
+ *
+ * Step 2: Group the cases into blocks based on how we can combine them
+ *
+ * Eg: case 0: ptr->x = 1; break; // similar code
+ * case 1: ptr->y = 1; break; // similar code
+ * ------Combined block ----
+ * case 0:
+ * case 1: PTR_OFFSET_TYPE(ptr, table[i].offset) = 1; break;
+ * This is an important step because we save code space by
+ * mapping many cases to smaller number of blocks. In the above
+ * we use index to get the right offset of the ptr.
+ *
+ * Step 3: Assign block IDs to each block. Put the case ID, block ID
+ * and other information such as offsets of ptr in a global
+ * table.
+ *
+ * Step 4: During run-time , search through the global table, find the
+ * matching case ID, and execute the common code. Next get the
+ * block ID and execute the block specific code. For the index,
+ * retrieve it from the table for the corresponding case ID.
+ *
+ * Step 5: If no matching case ID is found, error it out.
+ *
+ * Let's look at the optimization code for the above switch.
+ * The code below searches for the list->id in a global table where
+ * we store all the case values along with block numbers and other
+ * information. After we find a valid id in the table , we execute the
+ * common code for all cases first and then we retrieve the block id.
+ * The block id is necesary to determine which block does the id belong
+ * to. This is used to execute block specific code. Similar to switch
+ * cases ONLY here we try to minimize the no of blocks.
+ *
+ * In this example , we store the offsets of field names of a ptr in the
+ * global table.This is necessary to combine cases with "similar" but
+ * not "same" codes.
+ *
+ * Eg: case 0: ptr->x = 1; break; // similar code
+ * case 1: ptr->y = 1; break; // similar code
+ * -- Combined block ----
+ * case 0:
+ * case 1: PTR_OFFSET_TYPE(ptr, table[i].offset) = 1; break;
+ *
+ * By reducing the number of blocks we save on Code space. After we
+ * finish our work , we exit the for loop and check for invalid ID
+ * passed by the upper layer. This is akin to default in the
+ * switch block
+ *
+ * CAUTION: If there is any change in the switch above, this code
+ * along with the tables have to be re-written and changed according
+ * to the new behaviour of the switch. Examples include adding a new
+ * case in the switch. The reason for all this mumbo-jumbo is to
+ * reduce code size in VBIOS, where we are running out of code space.

+ * table (data structure of function pointers).
+ *
+ * Typical initialization will follow these steps:
+ * - Initialize the HAL by calling igd_driver_init() to
+ * detect supported chipsets without altering the hardware. If a
+ * supported device is found the _igd_init_info data structure will be
+ * populated indicating the chipset name and PCI information for the device.
+ * A driver handle that should be used during the rest of the
+ * initialization process will be returned.
+ *
+ * - Call igd_driver_config() to prepare the hardware for use. Until this
+ * point there has been no alteration of the hardware. After the
+ * driver has been configured the igd_get_config_info() function can
+ * be used. Only a subset of the _igd_config_info data will be available
+ * at this time as the modular HAL components have not been initialized.
+ *
+ * - Call igd_module_init() to initialize the modular components of the
+ * driver. This function accepts a set of parameters that can alter
+ * default behavior. A provided dispatch table will be populated with
+ * the entry points used for hardware operations during the life of

+ * These flags apply to a surface and indicate features of the surface
+ * that should be considered during render operations such as
+ * _igd_dispatch::blend()
+ *
+ * - IGD_RENDER_OP_BLEND: This surface should be blended with other
+ * surfaces during rendering. In calls to _igd_dispatch::blend() this
+ * surface will blend with those below it in the stack or the destination
+ * surface (when the surface is the bottom-most in the stack).
+ * Note: xRGB surfaces used with this render op will convert to ARGB
+ * surfaces with an alpha of 1.0. Without this render op xRGB surfaces
+ * will preserve the x value from the source.
+ *
+ * - IGD_RENDER_OP_PREMULT: The surface contains a pre-multipled alpha
+ * value. This indicates that the per-pixel color values have already been
+ * multipled by the per-pixel alpha value. Without this bit set it is
+ * necessary to perform this multiplication as part of a blend operation.
+ *
+ * - IGD_RENDER_OP_ALPHA: The surface contains a global alpha. All pixel
+ * values are multiplied against the global alpha as part of any blend
+ * operation. Global alpha is used exclusive of Diffuse color.
+ *
+ * - IGD_RENDER_OP_DIFFUSE: The surface contains a single diffuse color.
+ * This flag is used with alpha-only surfaces or surfaces of constant
+ * color. Diffuse is used exclusively of Global Alpha.
+ *
+ * - IGD_RENDER_OP_CHROMA: THe surface contains a chroma-key. Pixel
+ * values between chroma_high and chroma_low will be filtered out.
+ *
+ * - IGD_RENDER_OP_COLORKEY: The surface contains a colorkey. This is used
+ * on mask surfaces to indicate the location of pixels that may be drawn
+ * on the destination. Only pixels with values between chroma_high and
+ * chroma_low should "pass through" the mask to the destination. Other pixels
+ * will be filered out.
