2018-04-28nb/intel/i945/gma: Skip native VGA init for ACPI S3 resumePaul Menzel
Currently, native VGA initialization takes 90 ms during resume. But, it is not needed. So, skip it to save that time. Note, it is assumed that ACPI aware operating systems ship the appropriate drivers to initialize the graphics device. With Linux, if the module/driver *i915* is not loaded, then the display will stay black. TEST=On Lenovo X60t with Debian and Linux 4.15.11-1~bpo9+1, suspend and resume system and notice display is correctly initialized by the driver i915 after resume. Notice the messages below. ``` PCI: 00:02.0 init ... Skipping native VGA initialization when resuming from ACPI S3.

Port the ACPI opregion implementation that resides in drivers/intel/gma to older platforms. It allows to include a vbt.bin and allows GNU/Linux to load the opregion as ASLS is being set. Windows' Intel will likely ignore it as it relies on legacy VBIOS to be loaded at 0xc0000. Tested successfully on DG43GT (x4x) with vbt.bin, with X200 (gm45) with vendor option rom and D945GCLF (i945) with fake vbt.

2017-03-18nb/i945/gma.c: Refactor panel setupArthur Heymans
This reuses some of gm45 code to set up the panel. Panel start and stop delays and pwm frequency can now be set in devicetree. Linux does not make the difference between 945gm and gm45 for panel delays, so it is safe to assume the semantics of those registers are the same. The core display clock is computed according to "Mobile Intel® 945 Express Chipset Family" Datasheet. This selects Legacy backlight mode since most targets have some smm code that rely on this. This sets the same backlight frequency as vendor bios on Thinkpad X60 and T60. A default of 180Hz is selected for the PWM frequency if it is not defined in the devicetree, this might be annoying for displays that are LED backlit, but is a safe value for CCFL backlit displays.

2016-09-30i945/gma.c: use linux code to calculate divisorsArthur Heymans
The code to compute n, m1, m2, p1 divisors is not correct in coreboot and on some targets hits a working mode at lower refresh rate, which is why display is working on some targets. The divisors must be such "refclk * (5 * (m1 + 2) + (m2 + 2))/ (n + 2) / (p1 * p2)" is as close as possible to the target frequency (which is defined by the resolution and refresh rate). This patch also fixes the reference frequency. This patch reuses linux (4.1) code from drivers/gpu/drm/i915/intel_display.c to correctly compute divisors. The result is that some previously not working displays, like many displays found on the Lenovo T60 might work now. Some examples of T60 displays that were known to not work (in payload): Samsung LTN141XA-L01 (14.1" 1024x768) LG-Philips LP150X09 (15.1" 1024x768) IDtech N150U3-L01 (15.1" 1600x1200) IDtech IAQX10N (15.1" 2048x1536) Samsung LTN154X3-L0A (15.4" 1280x800) LG-Philips LP150E06-A5K4 (15.1" 1400x1050) Tested on T60 with 1024x786.

On i945 the vram size is the default 8mb. It is also possible to set it 1mb or 0mb hardcoding the GGC register in early_init.c The intel documentation on i945, "Mobile Intel® 945 Express Chipset Family datasheet june 2008" only documents those three options. They are set using 3 bits. The documententation also makes mention of 4mb, 16mb, 32mb, 48mb, 64mb but not how to set it. The other non documented (straight forward) bit combinations allow to change the VRAM size to those other states. What this patch does is: - add those undocumented registers with their respective vram size to the i945 NB code; - make this a cmos option on targets that have this northbridge. TEST: build, flash to target, set cmos as desired and boot linux. On Debian it can be found using "dmesg | grep stolen".

2015-05-28igd.asl rewriteVladimir Serbinenko
Old igd.asl had inconsistent addresses (between _DOD and actual device) and ghost devices. Any of those is enough to make brightness on windows fail and make igd.asl out-of-ACPI-spec. Also old code favoured ridiculous copying of the same thing 6 times per chipset. Leave only hooking up and chipset-specific part in chipset directory. Move NVS handling and ACPI-spec parts to a common file.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

2014-08-20intel/i945/gma: Place GTT below top of memoryPaul Menzel
Since commit 17fec8a0 [1] drm/i915: Use Graphics Base of Stolen Memory on all gen3+ present in the Linux kernel since version 3.12, 3D does not work anymore [2]. Comparing the graphics registers, in this case that means output of `intel_reg_dumper`, the vendor Video BIOS is setting the register PGTBL_CTL/PGETBL_CTL, only documented in the i965 datasheet [3], to `0x3ffc0001` on a system with 1 GB of RAM, while native graphics init sets it to `0x3f800001`. Currently native graphis init sets the GTT right above the base address of stolen memory. The Video BIOS sets it below the top of memory. The Linux Intel driver expects it to be below top of memory, so do it this way, by setting the address to TOM minus the size of the GTT, which is hardcoded to 256 KiB. As `PGETBL_CTL` is zero by default, reading its value in the beginning is not necessary and is only confusing. Make it clear that the code calculates the value. There is still a PTE error reported during boot, but 3D works with Linux 3.12+ and no user visible problems are shown.
