2017-04-14nb/intel/i945: Fix PEG port on 945gcArthur Heymans
Vendor BIOS leaves UPMC1 untouched (on 945gc the default is 0x0203). Not running PCIEx16 init which is valid for 945gm seems to fix all issues and instabilities related to the PEG port. According to lspci the link width is at the desired x16. It is unknown if devices requesting a lower width work automatically or need more configuration. What happens is that IGD gets disabled by the disable function in gma.c when an external GPU is found unless CONFIG_ONBOARD_VGA_IS_PRIMARY is set. Setting IGD as secondary makes Linux (4.10) hang, so this behavior is a requirement for now. TESTED on P5GC-MX with a discrete GPU and both CONFIG_ONBOARD_VGA_IS_PRIMARY set and unset.

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.

2017-02-04drivers/intel/gma/vbt: Add Kconfig symbol for SSC refNico Huber
The selection of the SSC reference frequency for LVDS was based on a completely unrelated clock. The `ssc_freq` flag should be set when the SSC reference runs at a different frequency than the general display reference clock (DREF). For most platforms, there is no choice, i.e. for i945 and gm45 the SSC reference always differs from the display reference clock (i945: 66Mhz SSC vs. 48MHz DREF; gm45: 100MHz SSC vs. 96Mhz DREF), for Nehalem and newer, it's the same frequency for SSC/non-SSC (120MHz). The only, currently supported platform with a choice seems to be Pineview, where the alternative is 100MHz vs. the default 96MHz.

2017-01-10nb/intel/945gc: Hardcode the integrated graphic frequenciesArthur Heymans
The code to set the igd frequencies is written with the mobile version of the 945 chipset in mind and seems to cause cause strange igd related problems on the desktop versions. Some possible problems are: * on 800MHz fsb CPUs the igd sometimes has artifacts on the screen; * on 800MHz fsb CPU memtest results vary a lot; * since a commit 45e11aa0a5 "Add/Combine Broadwell Chromebooks using variant board scheme" that does not affect this northbridge, the display shows garbage as soon as Linux (4.8) modesets the display. A fix is to hardcode the core display and render clocks to their maximum, potentially also improving graphical performance. Vendor bios on all boards in coreboot with this northbridge have the same value in this PCI config address. TESTED on P5GC-MX (display works fine again in Linux) and user reports of it making GA-945GCM-S2L run more stable.

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.

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.

On Broadwell, this reduces the number of 'remarks' in the IASL build from 222 to 3.

Since we're not intending to use those objects in the method, it shouldn't be an issue, but the warning is annoying and can mask real issues.

2015-06-05lib: Unify log2() and related functionsJulius Werner
This patch adds a few bit counting functions that are commonly needed for certain register calculations. We previously had a log2() implementation already, but it was awkwardly split between some C code that's only available in ramstage and an optimized x86-specific implementation in pre-RAM that prevented other archs from pulling it into earlier stages. Using __builtin_clz() as the baseline allows GCC to inline optimized assembly for most archs (including CLZ on ARM/ARM64 and BSR on x86), and to perform constant-folding if possible. What was previously named log2f on pre-RAM x86 is now ffs, since that's the standard name for that operation and I honestly don't have the slightest idea how it could've ever ended up being called log2f (which in POSIX is 'binary(2) LOGarithm with Float result, whereas the Find First Set operation has no direct correlation to logarithms that I know of). Make ffs result 0-based instead of the POSIX standard's 1-based since that is consistent with clz, log2 and the former log2f, and generally closer to what you want for most applications (a value that can directly be used as a shift to reach the found bit). Call it __ffs() instead of ffs() to avoid problems when importing code, since that's what Linux uses for the 0-based operation. CQ-DEPEND=CL:273023 BRANCH=None BUG=None TEST=Built on Big, Falco, Jerry, Oak and Urara. Compared old and new log2() and __ffs() results on Falco for a bunch of test values.

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>
2015-05-16i945: Disable check for 2-dimm support.Vladimir Serbinenko
The check is wrong. On Acer Aspire One it returns 0 despite 2 DIMMs working fine on the same channel if this check is disabled (tested by memtest). On boards that have only 1 DIMM per channel, the code will simply find no SPD and skip empty slot.

2015-04-29kbuild: automatically include northbridgesStefan Reinauer
This change switches all northbridge vendors and southbridges to be autoincluded by Makefile.inc, rather than having to be mentioned explicitly in northbridge/Makefile.inc or in northbridge/<vendor>/Makefile.inc. This means, vendor and northbridge directories are now "drop in", e.g. be placed in the coreboot directory hierarchy without having to modify any higher level coreboot files. The long term plan is to enable out of tree components to be built with a given coreboot version (given that the API did not change).

2015-01-06northbridge: Drop print_ implementation from non-romcc boardsStefan Reinauer
Because we had no stack on romcc boards, we had a separate, not as powerful clone of printk: print_*. Back in the day, like more than half a decade ago, we migrated a lot of boards to printk, but we never cleaned up the existing code to be consistent. instead, we worked around the problem with a very messy console.h (nowadays the mess is hidden in romstage_console.c and early_print.h) This patch cleans up the northbridge code to use printk() on all non-ROMCC boards.

Waiting for (a & 4) == 3 to become true proves futile unless you're searching for defective hardware or neutrino impact. While I'm not 100% sure that this is the actual intent (no data-sheets at hand, and the public ones are unhelpful as usual), it's the likely correct version and it's also boot-tested on intel/d945gclf. While at it, replace register number with the name found in the public datasheet.
