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.

2015-05-28igd.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>

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).

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.

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.

This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable.

As we move to supporting other systems we need to get rid of assembly where we can. The log2 function in src/lib is identical to the assembly one (tested for all 32-bit signed integers :-) and takes about 10 ns to run as opposed to 5ns for the non-portable assembly version. While speed is good, I think we can spare the 15 ns or so we add to boot time by using the C version only. Change-Id: Icafa565eae282c85fa5fc01b3bd1f110cd9aaa91 Signed-off-by: Ronald G.

2012-11-27Get rid of drivers classPatrick Georgi
The use of ramstage.a required the build system to handle some object files in a special way, which were put in the drivers class. These object files didn't provide any symbols that were used directly (but only via linker magic), and so the linker never considered them for inclusion. With ramstage.a gone, we can drop this special class, too.

2012-07-27Intel and GFXUMA: fix MTRR and use uma_resource()Kyösti Mälkki
Commit 2d42b340034ff005693482ef9ca34ce3e0f08371 changed the variable MTRR setup and removed compensation of uma_memory_size in the cacheable memory resources. Since the cacheable region size was no longer divisible by a large power of 2, like 256 MB, this caused excessive use of MTRRs. As first symptoms, slow boot with grub and poor user response. As a solution, register the actual top of low ram with ram_resource(), and do not subtract the UMA/TSEG regions from it. TSEG may require further work as the original did not appear exactly right to begin with. To have UMA as un-cacheable, use uma_resource().

2012-01-31northbridge/intel/i945: CHECK_SLFRCS_ON_RESUME Kconfig optionPeter Stuge
Originally brought up by Sven Schnelle in March 2011 http://patchwork.coreboot.org/patch/2801/ http://www.coreboot.org/pipermail/coreboot/2011-March/064277.html On some mainboards it may be neccessary to reset early during resume from S3 if the SLFRCS register indicates that a memory channel is not guaranteed to be in self-refresh. On other mainboards, such as Lenovo X60 and T60, the check always creates false positives, effectively making it impossible to resume. The SLFRCS register is documented on page 197 of Mobile Intel® 945 Express Chipset Family Datasheet Document Number: 309219-006 which is publically available, and the register indicates if a memory channel is guaranteed to be in self-refresh mode (if bit = 1), or that a memory channel *may or may not be* in self-refresh mode (if bit = 0). The register can thus only be used to positively learn that memory is in self-refresh. It is not known for sure that memory is *not* in self-refresh. The register is reset by the PWROK signal, which *should* go low during S3, and go high again when resuming, so it is unsurprising that SLFRCS has already been cleared when we read the register. Sven's measurements of the CKE signal on a ThinkPad shows that memory remains in self-refresh indefinitely, until coreboot re-initializes the memory controller, even when SLFRCS bits were = 0. Boards which require a warm reset when SLFRCS bits are cleared must now explicitly enable the check in the mainboard Kconfig file. This commit selects the new option in all existing i945 mainboards. A follow-up commit will remove the option for ThinkPads.
