2012-03-30MTRR: add alternate allocation method for odd memory mapsDuncan Laurie
With >= 4GB memory installed we get a memory map split in the middle due to remap that has boundaries that are inconveniently aligned for MTRRs due to the various UMA regions. 0000MB-2780MB 2780MB RAM (writeback) 2780MB-2782MB 2MB TSEG (uncached/SMRR) 2782MB-2784MB 2MB GFX GTT (uncached) 2784MB-2816MB 32MB GFX UMA (uncached) 2816MB-4096MB 1280MB EMPTY (N/A) 4096MB-5368MB 1272MB RAM (writeback) 5368MB-5376MB 8MB ME UMA (uncached) The default MTRR allocation method of trying to cover everything with one MTRR and then carve out a single uncached region does not work for the GPU aperture which needs write-combining type, and it also has issues trying to cover the uneven boundaries in the avaiable variable MTRRs. 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.

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.

2012-03-30Fix coreboot makefiles not to produce half baked output.Vadim Bendebury

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.

2012-03-29CBMEM CONSOLE: Add CBMEM console driver implementation.Vadim Bendebury
The CBMEM console driver saves console output in a CBMEM area, which then is made available to Linux applications for perusing. There are some system limitations which need to be worked around to achieve this goal: - some console traffic is generated before DRAM is initialized, leave alone CBMEM initialized. - after the RAM based stage starts, a lot of traffic is generated before CBMEM is initialized. As a result, the console log lives in three different places - the bottom of the cache as RAM space, the CBMEM buffer (where it is expected to be) and a static buffer used early in the RAM stage. When execution starts (in the cache as RAM mode), the console buffer is allocated at the bottom of the cache as RAM memory address range. Once DRAM is initialized, the CBMEM structure is initialized, and then the console buffer contents are copied from the bottom of the cache as RAM space into the CBMEM area right before the cache as RAM mode is disabled. The src/lib/cbmem_console.c:cbmemc_reinit() takes care of the copying. At this point the cache as RAM memory is about to be disabled, but the ROM stage is still going generating console output. To make sure this output is not lost, cbmemc_reinit() saves the new buffer address at a fixed location (0x600 was chosen for this), and the actual "printing" function checks to see if the RAM is already initialized (the stack is in RAM), and if so, gets the console buffer pointer from this location instead of using the cache as RAM address. When the RAM stage starts, a static buffer is used to store the console output, as the CBMEM buffer location is not known. Then, when CBMEM is reinitialized, cbmemc_reinit() again takes care of the copying. In case the allocated buffers are not large enough, the excessive data is dropped, and the copying routine adds some text to the output buffer to indicate that there has been data lost and how many characters were dropped.

We want to be able to share data between different phases of firmware (rom stage/ram stage/payload). Coreboot CBMEM seems an appropriate location for this data, but normally it is not initialized until coreboot reaches the ram stage. This change initializes the CBMEM while still in rom stage in case CONFIG_EARLY_CBMEM_INIT is set. Note that there is a discrepancy in how coreboot determines the size of DRAM at rom and ram stages, get_top_of_ram() is used at rom stage and is not defined for all platforms. Those platforms will have to define this function should they enable the CONFIG_EARLY_CBMEM_INIT flag.

Only the BSP CPU was able to start its hyper-threading CPU siblings. When an AP CPU attempts this it calls start_cpu() within start_cpu(), deadlocking the system with start_cpu_lock. At the time intel_sibling_init() is run, the BSP CPU is still walking the cpu_bus linked list in lapic_cpu_init: start_other_cpus(). A sibling CPU appended at the end of this list will get started. Also fail compile with #error if SERIAL_CPU_INIT==0, as microcode updates on hyper-threading sibling CPUs must be serialized. Tested with HT-enabled P4 Xeons on dual-socket604 platform.

2012-03-09Increase size of the coreboot table areaStefan Reinauer
Packing a device tree into the coreboot table can easily make the table exceed the current limit of 8KB. However, right now there is no error handling in place to catch that case. Increase the maximum memory usable for all tables from 64KB to 128KB and increase the maximum coreboot table size from 8KB to 32KB.

The code when reporting the coreboot table size did not account for the last added table record. This change fixes the problem. . rebuild coreboot, program it on the target, restart it . look for 'Wrote coreboot table at:' in the console log . observe the adequate table size reported $ grep 'Wrote coreboot table:' /tmp/cb.log Wrote coreboot table at: 00000500, 0x10 bytes, checksum c06f Wrote coreboot table at: 7f6fc000, 0x1a73 bytes, checksum 3e45 $ Change-Id: Ic55501a4ae06fab2bcda9aea58e362325f2edccf Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/703 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-03-09Clean up use of CONFIG_ variables in coreboot_table.cStefan Reinauer
CONFIG_ variables are used inconsistently within the file src/arch/x86/boot/coreboot_table.c. #ifdef will do the wrong thing if the option is disabled. #if (CONFIG_FOO == 1) is not needed.

I am not sure if the sub bus being 0 is a problem, or if the assumption there has to be at least one non empty link is just wrong. It certainly does not hurt to add a small consistency check in either case.
