Cleanup/tidy the texinfo documentation, courtesy of Paul <paukoen@gmail.com>

This was submitted on the mailing list. I further added the full list of
authors to the copying section. There were a few copyright authors missing in
the file that Paul submitted.

There are some TODO entries at the start of the document, which Paul left for
us. We need to work on those.

Also TODO: integrate this into build system, so that we have these options:
./build docs html
./build docs html-onepage
./build docs pdf
etc

-TODO: T60: find (for rare buggy CPUs that are unstable without microcode updates) if there is a workaround (patched kernel, special parameter, etc) So far, only 1 processor has been found to have issues. See microcode errata sheets http://download.intel.com/design/mobile/SPECUPDT/31407918.pdf and http://download.intel.com/design/mobile/SPECUPDT/30922214.pdf and then look at the debugging results collected in @uref{../resources/images/t7200q,t7200q} directory (q means quirk).

-@anchor{#lcd-panels-on-i945---fix-incompatible-panels}
-Fix T60 issues (see incompatible panels listed at @uref{../hcl/index.html#supported_t60_list,../hcl/index.html#supported_t60_list}).
-
-Run that tool (resources/utilities/i945gpu/intel-regs.py) as root on systems with the offending panels in:
-
-@itemize
-@item
-Coreboot (or libreboot, whatever) with VBIOS (disable native graphics also)
-@item
-(Factory BIOS also?)
-@end itemize
-
-This shows values in devicetree.cb and src/northbridge/intel/i945/gma.c, the idea is that you run it on factory bios or vbios and that it will (might) show different values: then you try those in the native graphics (in libreboot).
-
-Other values/registers might also need to be added to the script for these tests.
-
-check if intel_bios_reader from intel-gpu-tools reports the same value (BIOS has a hardcoded value) for PWM modulation frequency. This file can read the VBIOS (64K dump).
-
-Check other tools in intel-gpu-tools aswell, compare outputs. Possibly add more information to intel-regs.py output (submit changes to mtjm). Do oprom trace / replay (@uref{http://www.coreboot.org/User:GNUtoo#How_to_get_rid_of_the_vbios_of_the_x60_.5BNew_Version.5D,http://www.coreboot.org/User:GNUtoo#How_to_get_rid_of_the_vbios_of_the_x60_.5BNew_Version.5D})
-
-Study how EDID works and how gma.c handles it.
-
-Original getregs.py script can be found at @uref{http://hg.mtjm.eu/scripts/file/tip/intel-regs.py,http://hg.mtjm.eu/scripts/file/tip/intel-regs.py} written by Michał Masłowski.
-
-About fixing remaining LCD panels on 5345:@* 'polarity' is mentioned in coreboot log (cbmem -c). compare output (with working and non-working panel). (and see the other notes in future/index.html)
-
-There was a theory that working panels are 6bpc (bits per colour) and nonworking are 8bpc, but all EDIDs that we have here are for 6bpc panels.
-
-We should compare coreboot logs (from @code{cbmem -c} from systems with working and nonworking panels.
-
-How to dump EDID:
-
-# @strong{apt-get install i2c-tools}@* # @strong{modprobe i2c-dev}@* Find out the correct ID to use:@* # @strong{i2cdetect -l}@* Example:@* # @strong{i2cdump -y 2 0x50}

-@strong{Use 'drm.debug=0x06' kernel parameter when booting in grub!}
-
-Before each test run, boot a live USB and delete the old logs in /var/log (kernel log, xorg log, dmesg and so on).
-
-Load (from the ROM) the runningvga.bin for each LCD panel on each system; do not execute it, only load it! (coreboot will have to be modified). Rename the ROM appropriately, based on the system name and the panel name. coreboot_nativegfx_5868_plusrunningvga_t60_14_LTD141ECMB.rom, for instance. Keep a copy for later use.
-
-You are supposed to:
-
-@itemize
-@item
-enable native graphics in menuconfig
-@item
-include the self-modified VGA ROM (load, but not execute) - for reverse engineering the correct VBT tables.
-@end itemize
-
-With each boot, make notes about what you see and get logs using the @ref{#standard_test,standard test}. You will need the files from @ref{#intelvbttool_results,#intelvbttool_results} for each system.

-@chapter intelvbttool test results (VGA ROM dumps)
-@anchor{#intelvbttool-test-results-vga-rom-dumps}
-The VBIOS on i945 (intel gpu) platforms is self-modifying; that is, its contents change when you run it. intelvbttool takes a dump of the currently running vbios, and parses it.
-
-The idea is that we can extract the VBT tables using this knowledge, on the X60, X60 Tablet and T60 (Intel GPU).
-
-Here is an example of how VBT was implemented on the ThinkPad X230: @uref{http://review.coreboot.org/#/c/5396,http://review.coreboot.org/#/c/5396}.
-
-You'll need to build a T60 ROM with SeaBIOS and the VGA ROM (for Intel GPU). An X60 ROM is also needed (same configuration, using the VGA ROM for X60).
-
-T60 has DVI on its dock, make sure that the dock is attached when getting this output.
-
-Get intelvbttool here: @uref{http://review.coreboot.org/#/c/5842,http://review.coreboot.org/#/c/5842} (util/intelvbttool).
-
-Now dump a copy of the running VGA BIOS: @strong{$ sudo dd if=/dev/mem bs=64k of=runningvga.bin skip=12 count=1}@* Then do (and record the output):@* @strong{$ ./intelvbttool runningvga.bin > intelvbttool_out}
-
-Backup both files (runningvga.bin and intelvbttool_out), renaming them to match the system and LCD panel used. @uref{../misc/index.html#get_edid_panelname,../misc/index.html#get_edid_panelname} will show you how to get the name (model) of the LCD panel used.

-It might be the same issue I ran into with Paul on the X60 (not enough memory being allocated) since the same code works on T60 SXGA+ and UXGA, where GRUB actually display graphics.

-@strong{Add backlight controls:} in @emph{src/mainboard/lenovo/x60/devicetree.cb}, change @strong{gpu_backlight} to @strong{0x879F879E}
-
-That's all! @strong{This has also been backported into libreboot 5th release (line 1233 in src/mainboard/lenovo/x60/i915io.c)}. GNUtoo (Denis Carikli) told me about the register @strong{BLC_PWM_CTL} and that you could set it to control backlight. I read that address using devmem2 while running the VBIOS:@* @strong{# devmem2 0xe4361254 w}
-
-The change is also included in libreboot 6.
-
-When doing this, it gave back that value. The same trick was used to get backlight controls for T60 (see @ref{#t60_native_notes,#t60_native_notes}).

-Reading @strong{0xe4361254} (address) in Lenovo BIOS always yields FFFFFFFF, even when writing to it (and writing to it doesn't affect brightness controls). 'mtjm' on IRC found that the buttons (Fn keys) control /sys/class/backlight/acpi_video0 which has no affect on 61254 (BLC_PWM_CTL). This person says intel_backlight has different values and uses the register. devmem2 works, needs checking @strong{lspci -vv} for where the memory is mapped, which is different than on coreboot; mtjm found that it was 0xec061254 on his system (X60 Tablet), and the register value is different too. @strong{This is relevant, because we still don't know how backlight controls are actually handled. We got it working by accident. We need to know more.}.
-
-Intel-gpu-tools may prove useful for further debugging: @uref{http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/,http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/}
-
-mtjm says 0xe4300000 is an MMIO region of the gpu (lspci -vv shows it), 0x61254 (BLC_PWM_CTL) is a documented register. Searching the kernel driver for backlight shows that in intel_panel.c this register is used (there is an XXX comment about finding the right value, where recent kernels get it from.
-
-What we want to do is calculate a good value, instead of setting it in devicetree.cb. mtjm says about backlight physics: it has a light source , uses pulse width modulation (PWM) to turn it on/off, dimming is done by spending less time on. @strong{Note: this may not be correct; this person says that their understanding is based on how the Lenote yeeloong works}.
-
-mtjm goes on to say, that the register specifies the frequency used for PWM in its depending on the GPU core frequency, so it might be possible to calculate it without hardcoded laptop-specific values. Therefore, I am supposed to find out the 'display core frequency' (mtjm says there might be a register for it; also, it might be in 5320 or the replay code) and the PWM modulation frequency. https://en.wikipedia.org/wiki/Backlight#Flicker_due_to_backlight_dimming
-
-phcoder (Vladimir Serbinenko) who is author of 5320 (review.coreboot.org) talks about 'duty cycle limit' and 'flickering frequency'.

-
-See @ref{#x60_cb5927_testing,#x60_cb5927_testing} for the original (and current) fix, for the replay code. Now we want to implement that on top of @uref{http://review.coreboot.org/#/c/5320,http://review.coreboot.org/#/c/5320} which is the current code for native graphics initialization on i945.
-
-src/northbridge/intel/i945/gma.c (using the 7c0000 hack) on 5320: @uref{../resources/misc/dumps/5320_7c0000_gma.c,5320_7c0000_gma.c} (rename it to gma.c, replacing the current one).
-
-The above is a hack (as is the original). A better (more correct) method is implemented in later versions of 5927, so that should also be adapted for 5320. For now, you can use the above fix.
-
-The correct way to do it is to set gtt address to (end of stolen memory - gtt size), which is what later versions of 5927 do (successfully).

-
