2012-04-16ACPI HEST table.zbao
HEST feature starts from ACPI 4.0. HEST is one of four kinds of tables of ACPI Platform Error Interfaces (APEI). In Windows world, APEI is called Windows Hardware Error Architecture (WHEA). APEI consists of four separate tables: 1. Error Record Serialization Table (ERST) 2. BOOT Error Record Table (BERT) 3. Hardware Error Source Table (HEST) 4. Error Injection Table (EINJ) All these 4 tables have the same header as FADT, MADT, etc. They are pointed by RSDP. For the HEST, it contains the error source. The types of them are defined as type description 1. Machine Check Exception (MCE) 2. Corrected Machine Check (CMC) 3. NMI Error 6. PCI Express Root Port AER 7. PCI Express Device AER 8. PCI Express Bridge AER 9. Generic Hardware Error Source Error source types 3, 4, and 5 are reserved for legacy reasons and must not be used. Currently AMD board only provide part of "Machine Check Exception (MCE)" & Corrected Machine Check (CMC)". we need to provide the header of each error source. Other types of Error Sources is in TODO list. Only persimmon is tested. Linux can add HEST feature. The dmesg says, ACPI: HEST 0000000066fe5010 00198 (v03 CORE COREBOOT 00000000 CORE 00000000) ...... HEST: Table parsing has been initialized. No more message is got. Windows can boot with this patch. Havent found a way to test it.

2012-04-03Add preprocessing capabilities to the cbfs-files mechanismPatrick Georgi
It's now possible to generate files that are about to be added to CBFS by specifying "sourcefile:method" as real file name. This makes the build system use the cbfs-files-preprocessor-$(method) function to create a file from sourcefile. That generated file is then added to CBFS. The first method to be defined is "nvramtool". It expects a plain text specification of the CMOS configuration and emits the binary format suitable for cmos.default.

2012-04-02Force coreboot mconf to create temp files in the output directoryVadim Bendebury
This change partially addresses the problem with attempting to generate coreboot image out of tree. The configuration step fails when in cheroot, if the destination directory is placed in /tmp. The problem is that the mconf package tries renaming the temporary file created in the local directory into the destination config file. If the destination root and the local directory are located on different file systems, the rename operation fails. The proper fix (still upcoming) would be to identify all places where mconf creates temp files, and make sure that all temp files get created in the destination tree. This change modifies just one location, which prevents building out of tree in the most common case. Test: run the following in the coreboot directory in chroot: (coreboot) cp config.lumpy .config (coreboot) /bin/rm -rf /tmp/cb (coreboot) CROSS_COMPILE=i686-pc-linux-gnu- make obj=/tmp/cb oldconfig (coreboot) CROSS_COMPILE=i686-pc-linux-gnu- make obj=/tmp/cb Observe the build succeed (it was failing during the config phase before this change) Change-Id: If4506e984b8afc192a1689c7b0aa956dd35f66c6 Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/815 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-03-31Fix issues with x86 memcpyMathias Krause
The x86 memcpy() implementation did not mention its implicit output registers ESI, EDI and ECX which might make this code miscompile when the compiler uses the value of EDI for the return value *after* the 'rep movsb' has completed. That would break the API of memcpy as this would return 'dst+len' instead of 'dst'. Fix this possible bug by removing the wrong comment and listing all output registers as such (using dummy stack variables that get optimized away). Also the leading 'cld' is superflous as the ABI mandates the direction flag to be cleared all the time when we're in C (see <http://gcc.gnu.org/gcc-4.3/changes.html>) and we have no ASM call sites that might require it to be cleared explicitly (SMM might come to mind, but it clears the DF itself before passing control to the C part of the SMI handler). Last but not least fix the prototype to match the one from <string.h>.

2012-03-31Add support for RAM-less multi-processor initKyösti Mälkki
For a hyper-threading processor, enabling cache requires that both the BSP and AP CPU clear CR0.CD (Cache Disable) bit. For a Cache-As-Ram implementation, partial multi-processor initialisation precedes raminit and AP CPUs' 16bit entry must be run from ROM. The AP CPU can only start execute real-mode code at a 4kB aligned address below 1MB. The protected mode entry code for AP is identical with the BSP code, which is already located at the top of bootblock. This patch takes the simplest approach and aligns the bootblock 16 bit entry at highest possible 4kB boundary below 1MB. The symbol ap_sipi_vector is tested to match CONFIG_AP_SIPI_VECTOR used by the CAR code in romstage. Adress is not expected to ever change, but if it does, link will fail.

My goal was to make a minimal set of changes and avoid modifying behavior on existing systems with an algorithm that is not always optimal for a typical memory layout. So the flag 'above4gb=2' will change these allocation behaviors: 1) Detect the number of available variable MTRRs rather than limiting to hardcoded value. We need every last MTRR. 2) Don't try to cover all RAM with one MTRR, instead let each RAM region get covered independently. 3) Don't assume uma_memory_base is part of the last region and increase the size of that region. In this case the UMA region is carved out from the lower memory region and it is already declared as part of the ram region. 4) If a memory region can't be covered with MTRRs >= 16MB then instead make a larger region and trim it with uncached MTRRs.

It does not seem to cause noticeable problems but in heavy suspend/resume testing I saw a suspicious crash in the kernel when trying to bring one of the CPUs back online.

2012-03-30Prepare the BIOS data areas before device init.Duncan Laurie
Since we do not run option roms in normal mode nothing was initializing the BDA/EBDA and yet Linux depends very much on it having sane values here. For the most part the kernel tries to work around this not being initialized, but every once in awhile (1/300 boots or so) it would end up reading something that looked sane from BDA but was not and then it would panic. In this change the EBDA is unconditionally setup before devices are initialized. I'm not set on the location in dev_initialize() but there does not seem to be another place to hook it in so that it runs just once for ALL platforms regardless of whether they use option roms or not. (possibly hardwaremain?) The EBDA setup code has been moved into its own location in arch/x86/lib/ebda.c so it can be compiled in even if the option rom code is not. The low memory size is still set to 1MB which is enough to make linux happy without having to hook into each mainboard to get a more appropriate value. The setup_ebda() function takes inputs so it could be changed for a mainboard if needed. OLD/BROKEN would read garbage. Examples from different boots: ebda_addr=0x75e80 lowmem=0x1553400 ebda_addr=0x5e080 lowmem=0x3e51400 ebda_addr=0x7aa80 lowmem=0x2f8a800 NEW/FIXED now reads consistent values: ebda_addr=0xf6000 lowmem=0x100000 Change-Id: I6cb79f0e3e43cc65f7e5fe98b6cad1a557ccd949 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: http://review.coreboot.org/769 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-03-30Allow components smaller than declared size.Vadim Bendebury
idftool was failing to add the ME blobs into the output image in case the blob size does not exactly match the size allocated for it in the flashrom structure. It is difficult to set the field in the structure to exactly match the size (for some reason Intel flash tool fails to insert the correct size even when given the exact ME blob). On the other hand there is no harm in using am ME blob smaller than the allocated size, this change modifies the tool building the image to allow for smaller components.

This avoids using EBX and instead uses EDI where possible, and ESI when necessary to get the EBX value out. This allows me to enable -fpic for SMM TSEG code. Also add a new CPUID extended function to query with ECX set.

2012-03-30Revamp cbmem.py to use the coreboot tables.Gabe Black
This change makes significant changes to cbmem.py to make it use the coreboot tables to find the memory console and timestamp areas instead of looking for the in memory table TOC structure. That appears to be more robust and gets cbmem.py working again after some unrelated changes that affected memory layout. It also introduces some small infrastructure to make accessing C style structures in physical memory easier and more transparent.

2012-03-30Fix coreboot makefiles not to produce half baked output.Vadim Bendebury
It looks like the cbfstool utility generates the output file even when it fails to generate it properly. This causes make, if started second time in a row, after cbfstool failure, to continue beyond the point of failure (as the corrupted output file is present in the output tree, the second make invocation presumes that it is valid, as it is newer than the dependencies). The output file should be created only when successful, in an atomic operation. There could be other places in the make system which require a similar fix, this needs to be investigated further.
