2014-01-06CBMEM: Fix allocation for static CBMEMKyösti Mälkki
CBMEM console buffer size is adjustable in menuconfig, but this would not correctly adjust the overall allocation made for CBMEM. HIGH_MEMORY_SIZE is aligned to 64kB and definitions are moved down in the header file as HIGH_MEMORY_SIZE is not used with DYNAMIC_CBMEM. Try to continue boot even if CBMEM cannot be created. This error would only occur during development of new ports anyways and more log output is better.

2013-05-16x86: add cache-as-ram migration optionAaron Durbin
There are some boards that do a significant amount of work after cache-as-ram is torn down but before ramstage is loaded. For example, using vboot to verify the ramstage is one such operation. However, there are pieces of code that are executed that reference global variables that are linked in the cache-as-ram region. If those variables are referenced after cache-as-ram is torn down then the values observed will most likely be incorrect. Therefore provide a Kconfig option to select cache-as-ram migration to memory using cbmem. This option is named CAR_MIGRATION. When enabled, the address of cache-as-ram variables may be obtained dynamically. Additionally, when cache-as-ram migration occurs the cache-as-ram data region for global variables is copied into cbmem. There are also automatic callbacks for other modules to perform their own migration, if necessary.

2013-03-21cbmem: dynamic cbmem supportAaron Durbin
This patch adds a parallel implementation of cbmem that supports dynamic sizing. The original implementation relied on reserving a fixed-size block of memory for adding cbmem entries. In order to allow for more flexibility for adding cbmem allocations the dynamic cbmem infrastructure was developed as an alternative to the fixed block approach. Also, the amount of memory to reserve for cbmem allocations does not need to be known prior to the first allocation. The dynamic cbmem code implements the same API as the existing cbmem code except for cbmem_init() and cbmem_reinit(). The add and find routines behave the same way. The dynamic cbmem infrastructure uses a top down allocator that starts allocating from a board/chipset defined function cbmem_top(). A root pointer lives just below cbmem_top(). In turn that pointer points to the root block which contains the entries for all the large alloctations. The corresponding block for each large allocation falls just below the previous entry. It should be noted that this implementation rounds all allocations up to a 4096 byte granularity. Though a packing allocator could be written for small allocations it was deemed OK to just fragment the memory as there shouldn't be that many small allocations. The result is less code with a tradeoff of some wasted memory. +----------------------+ <- cbmem_top() | +----| root pointer | | | +----------------------+ | | | |--------+ | +--->| root block |-----+ | | +----------------------+ | | | | | | | | | | | | | | alloc N |<----+ | | +----------------------+ | | | | | | | | | \|/ | alloc N + 1 |<-------+ v +----------------------+ In addition to preserving the previous cbmem API, the dynamic cbmem API allows for removing blocks from cbmem. This allows for the boot process to allocate memory that can be discarded after it's been used for performing more complex boot tasks in romstage. In order to plumb this support in there were some issues to work around regarding writing of coreboot tables. There were a few assumptions to how cbmem was layed out which dictated some ifdef guarding and other runtime checks so as not to incorrectly tag the e820 and coreboot memory tables. The example shown below is using dynamic cbmem infrastructure. The reserved memory for cbmem is less than 512KiB. coreboot memory table: 0. 0000000000000000-0000000000000fff: CONFIGURATION TABLES 1. 0000000000001000-000000000002ffff: RAM 2. 0000000000030000-000000000003ffff: RESERVED 3. 0000000000040000-000000000009ffff: RAM 4. 00000000000a0000-00000000000fffff: RESERVED 5. 0000000000100000-0000000000efffff: RAM 6. 0000000000f00000-0000000000ffffff: RESERVED 7. 0000000001000000-000000007bf80fff: RAM 8. 000000007bf81000-000000007bffffff: CONFIGURATION TABLES 9. 000000007c000000-000000007e9fffff: RESERVED 10. 00000000f0000000-00000000f3ffffff: RESERVED 11. 00000000fed10000-00000000fed19fff: RESERVED 12. 00000000fed84000-00000000fed84fff: RESERVED 13. 0000000100000000-00000001005fffff: RAM Wrote coreboot table at: 7bf81000, 0x39c bytes, checksum f5bf coreboot table: 948 bytes.

In order to provide some insight on what code is executed during coreboot's run time and how well our test scenarios work, this adds code coverage support to coreboot's ram stage. This should be easily adaptable for payloads, and maybe even romstage. See http://gcc.gnu.org/onlinedocs/gcc/Gcov.html for more information. To instrument coreboot, select CONFIG_COVERAGE ("Code coverage support") in Kconfig, and recompile coreboot. coreboot will then store its code coverage information into CBMEM, if possible. Then, run "cbmem -CV" as root on the target system running the instrumented coreboot binary. This will create a whole bunch of .gcda files that contain coverage information. Tar them up, copy them to your build system machine, and untar them. Then you can use your favorite coverage utility (gcov, lcov, ...) to visualize code coverage.

Just two values are being added now, this will have to be used more extensively and also integrated into payloads to provide more comprehensive boot process time measurements. Also, since the CBMEM area could already contain a section (from the previous run, before reset), when processing a section addition request we should check if a section already exists and return its address, if so.

Other chipsets so far only ever set acpi_slp_type to 0 and 3, so the added check for acpi_slp_type == 2 (resume from S2) should not change behaviour of other boards: northbridge/intel/i945/northbridge.c:256:extern u8 acpi_slp_type; northbridge/intel/i945/northbridge.c:263: acpi_slp_type=0; northbridge/intel/i945/northbridge.c:267: acpi_slp_type=3; northbridge/intel/i945/northbridge.c:271: acpi_slp_type=0; southbridge/intel/i82801gx/i82801gx_lpc.c:171:extern u8 acpi_slp_type; southbridge/via/vt8237r/vt8237r_lpc.c:149:extern u8 acpi_slp_type; southbridge/via/vt8237r/vt8237r_lpc.c:238: acpi_slp_type = ((tmp & (7 << 10)) >> 10) == 1 ? 3 : 0 ; southbridge/via/vt8237r/vt8237r_lpc.c:239: printk(BIOS_DEBUG, "SLP_TYP type was %x %x\n", tmp, acpi_slp_type); Change-Id: I13feff0b8f49aa988e5467cdbef02981f0a6be8a Signed-off-by: Tobias Diedrich <ranma+coreboot@tdiedrich.de> Signed-off-by: Patrick Georgi <patrick@georgi-clan.de> Reviewed-on: http://review.coreboot.org/188 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

the get_cbmem_toc because macro magic did not work well. The writes to NVRAM are not used in asrock board (k8 pre rev f) but they should work when used with am2 boards.

2010-11-221) wraps the s3 parts of chipset code/memory init code with if ↵Rudolf Marek
CONFIG_HAVE_ACPI_RESUME == 1 getting rid of ugly define in romstage.c 2) the patch implements get_cbmem_toc in chipset specific way if defined. On Intel targets it should be unchanged. On K8T890 the the cbmem_toc is read from NVRAM. Why you ask? Because we cannot do it as on intel, because the framebuffer might be there making it hard to look for it in memory (and remember we need it so early that everying is uncached) 3) The patch removes hardcoded limits for suspend/resume save area (it was 1MB) on intel. Now it computes right numbers itself. 4) it impelements saving the memory during CAR to reserved range in sane way. First the sysinfo area (CAR data) is copied, then the rest after car is disabled (cached copy is used). I changed bit also the the copy of CAR area is now done uncached for target which I feel is more right. I think I did not change the Intel suspend/resume behaviour but best would be if someone can test it. Please note this patch was unfinished on my drive since ages and it would be very nice to get it in to prevent bit rotten it again. Now I feel it is done good way and should not break anything. I did a test with abuild and it seems fine.

- Hook up malloc() debug code via CONFIG_DEBUG_MALLOC. Only show it in menuconfig if at least DEBUG or SPEW are selected as loglevel, as this code does additional printk(BIOS_DEBUG, ...) calls which would otherwise not be visible anyway. - Similarly, make DEBUG_CAR and REALMODE_DEBUG only visible if thr DEBUG or SPEW loglevel is selected. - Get rid of a custom "debug" macro, use printk() as usual.
