* Intel 945: Select LAPIC_MONOTONIC_TIMER for X86EMU_DEBUG_TIMINGSDenis 'GNUtoo' Carikli2013-06-051-0/+1
| | | | | | | | | | | | | | | | | X86EMU_DEBUG_TIMING is needed for producing i915tool compatible output. So add its dependencies to the i945’s Kconfig in order to be able to use X86EMU_DEBUG_TIMINGS, which depends on HAVE_MONOTONIC_TIMER which LAPIC_MONOTONIC_TIMER provides/selects. Note that UDELAY_LAPIC is already selected by the Intel CPU.

* Move the MARK_GRAPHICS_MEM_WRCOMB to x86 architectureRonald G. Minnich2013-06-042-16/+0
| | | | | | | | | | | | | | | | The MARK_GRAPHICS_MEM_WRCOMB was spreading like a cancer since it was defined in sandybridge. It is really more of an x86 thing however, and we now have three systems that can use it. I considered making this more general, since it technically can apply to PTE-based systems like ARM, and maybe we should. But the 'WRCOMB' moniker is usually closely tied to the x86.

* AMD Fam 15tn: Use all memory on systems with more than 4 GBSiyuan Wang2013-06-041-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Take a Parmer board with 4G memory as an example. Use 'cat /proc/meminfo' to check memory, it reads 'MemTotal 3327540kB'. Parmer uses 512M as video memory when it has 4G. 3327540+512*1024 = 3851828(kB), so some memory is lost. When Parmer has 4G memory, TOM2 low is 0x1F000000, TOM2 high is 0x00000001. But in e820 table or coreboot table, the last item is 6: 0000000100000000 - 0000000118000000 = 1 RAM This is not correct, it should be 6: 0000000100000000 - 000000011f000000 = 1 RAM This patch changes the memory layout when TOM2 is set.

* Persimmon/Fam14/SB800 DSDT: Split into common areasMike Loptien2013-04-111-0/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split the Persimmon DSDT into common code areas. For example, split the Southbridge specific code into the Southbridge directory and CPU specific code into the CPU directory. Also adding the superio.asl file to the Persimmon DSDT tree. This file is empty for the moment but will be necessary in the future. I have also emptied the thermal.asl file in the mainboard directory because it does not seem to perform as intended (fan control does not change when it is brought back into the code base) and it has been inside a '#if 0' statement for a long time. Removing it until it is decided that it is actually necessary. This change was verified in three different ways: 1. Visual comparison of the compiled DSDT pulled from the Persimmon after booting into Linux using the ACPI tools acpidump, acpixtract, and iasl. The comparison was done between the DSDT before and after doing the split work. This test is somewhat difficult considering the expanse of the changes. Blocks of code have been moved, and others changed. 2. Linux logs were dumped before and after the DSDT split. Logs dumped and compared include dmesg and lspci -tv. Neither log changed significantly between the two compare points. 3. The test suite FWTS was run on the Coreboot build both before and after doing the DSDT split with the command 'sudo fwts -b -P -u'. The flag -b specifies all batch jobs, -P specifies all power tests, and -u specifies utilities. Interactive jobs were not run as most of them consist of laptop checks. Again, there were no significant changes between the two endpoints. These tests lead me to believe that there was no change in the functionality of the ACPI tables apart from what is known and expected. This patch is the first of a series of patches to split the DSDT. The ASRock patch was merged before this one and breaks the ASROCK E350M1 build (patch 8d80a3fb: http://review.coreboot.org/#/c/3050/). Please be aware of this dependency when pulling these patches. Other patches that depend on this patch are 'AMD Fam14: Split out the AMD Fam14 DSDT' (http://review.coreboot.org/#/c/3051/) and 'Fam14 DSDT: Also return for unrecognized UUID in _OSC' (http://review.coreboot.org/#/c/3052/) Change-Id: I53ff59909cceb30a08e8eab3d59b30b97c802726 Signed-off-by: Mike Loptien <mike.loptien@se-eng.com> Reviewed-on: http://review.coreboot.org/3048 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martin.roth@se-eng.com>

* x86: add new mtrr implementationAaron Durbin2013-03-291-14/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old MTRR code had issues using too many variable MTRRs depending on the physical address space layout dictated by the device resources. This new implementation calculates the default MTRR type by comparing the number of variable MTRRs used for each type. This avoids the need for IORESOURE_UMA_FB because in many of those situations setting the default type to WB frees up the variable MTTRs to set that space to UC. Additionally, it removes the need for IORESOURCE_IGNORE_MTRR becuase the new mtrr uses the memrange library which does merging of resources. Lastly, the sandybridge gma has its speedup optimization removed for the graphics memory by writing a pre-determined MTRR index. That will be fixed in an upcoming patch once write-combining support is added to the resources. Slight differences from previous MTRR code: - The number of reserved OS MTRRs is not a hard limit. It's now advisory as PAT can be used by the OS to setup the regions to the caching policy desired. - The memory types are calculated once by the first CPU to run the code. After that all other CPUs use that value. - CONFIG_CACHE_ROM support was dropped. It will be added back in its own change. A pathological case that was previously fixed by changing vendor code to adjust the IO hole location looked like the following: MTRR: Physical address space: 0x0000000000000000 - 0x00000000000a0000 size 0x000a0000 type 6 0x00000000000a0000 - 0x00000000000c0000 size 0x00020000 type 0 0x00000000000c0000 - 0x00000000ad800000 size 0xad740000 type 6 0x00000000ad800000 - 0x00000000d0000000 size 0x22800000 type 0 0x00000000d0000000 - 0x00000000e0000000 size 0x10000000 type 1 0x00000000e0000000 - 0x0000000100000000 size 0x20000000 type 0 0x0000000100000000 - 0x000000014f600000 size 0x4f600000 type 6 As noted by the output below it's impossible to accomodate those ranges even with 10 variable MTRRS. However, because the code can select WB as the default MTRR type it can be done in 6 MTRRs: MTRR: default type WB/UC MTRR counts: 6/14. MTRR: WB selected as default type. MTRR: 0 base 0x00000000ad800000 mask 0x0000007fff800000 type 0 MTRR: 1 base 0x00000000ae000000 mask 0x0000007ffe000000 type 0 MTRR: 2 base 0x00000000b0000000 mask 0x0000007ff0000000 type 0 MTRR: 3 base 0x00000000c0000000 mask 0x0000007ff0000000 type 0 MTRR: 4 base 0x00000000d0000000 mask 0x0000007ff0000000 type 1 MTRR: 5 base 0x00000000e0000000 mask 0x0000007fe0000000 type 0 Change-Id: Idfcc78d9afef9d44c769a676716aae3ff2bd79de Signed-off-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/2889 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

| | | | | | | | | | | | | | | | | | | | | | Convert the existing haswell code to support reloctable ramstage to use dynamic cbmem. This patch always selects DYNAMIC_CBMEM as this option is a hard requirement for relocatable ramstage. Aside from converting a few new API calls, a cbmem_top() implementation is added which is defined to be at the begining of the TSEG region. Also, use the dynamic cbmem library for allocating a stack in ram for romstage after CAR is torn down. Utilizing dynamic cbmem does mean that the cmem field in the gnvs chromeos acpi table is now 0. Also, the memconsole driver in the kernel won't be able to find the memconsole because the cbmem structure changed.

This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

It also adds support for the LynxPoint-LP GPE0 register block and the SMI/SCI routing differences. The FADT is updated to report the new 256 byte GPE0 block on wtm2/wtm2 boards which is too big for the 64bit X_GPE0 address block so that part is zeroed to prevent IASL and the kernel from complaining about a mismatch. This was tested on WTM2. Unfortunately I am still unable to get an SCI delivered from the EC but I suspect that is due to a magic command needed to put the EC in ACPI mode. Instead I verified that all of the power management and GPIO registers were set to expected values. I also tested transitions into S3 and S5 from both the kernel and by pressing the power button at the developer mode screen and they all function as expected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change: This is the initial step for moving the AMD F15 & HUDSON1,2,3 SPD-read callout out of the mainboard directories and into the wrapper. The next step is to update the platforms to use this routine in BiosCallouts.c and to delete the code from the mainboard directories. The DIMM addresses should be moved into devicetree.cb. If there are significant differences or reasons that the mainboard needs to override this code, it's perfectly reasonable to keep using the version in the mainboard, but this allows us to remove duplicated code and simplify the mainboard directories. Notes: This started by duplicating what was in Dinar, and was changed to use the devicetree.cb structures. Significant cleanup and magic number reduction was done as well. It is intended that this file will not be included in ramstage as the DIMM init is all done in romstage. This is similar to what was done for Parmer/Thatcher in commit 7fb692bd - http://review.coreboot.org/#/c/2190/ Fam15tn: Move SPD read from mainboards into wrapper Yes, it would make sense to split this into two separate files and move the SMBus initialization and access into the southbridge wrapper.
