2020-04-23rules.h: Rename ENV_VERSTAGE to ENV_SEPARATE_VERSTAGEJulius Werner
When CONFIG_SEPARATE_VERSTAGE=n, all verstage code gets linked into the appropriate calling stage (bootblock or romstage). This means that ENV_VERSTAGE is actually 0, and instead ENV_BOOTBLOCK or ENV_ROMSTAGE are 1. This keeps tripping up people who are just trying to write a simple "are we in verstage (i.e. wherever the vboot init logic runs)" check, e.g. for TPM init functions which may run in "verstage" or ramstage depending on whether vboot is enabled. Those checks will not work as intended for CONFIG_SEPARATE_VERSTAGE=n. This patch renames ENV_VERSTAGE to ENV_SEPARATE_VERSTAGE to try to clarify that this macro can really only be used to check whether code is running in a *separate* verstage, and clue people in that they may need to cover the linked-in verstage case as well.

They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

Therefore, in order to make the cbmem console reinit flow work one needs the cbmem init hook infrastructure in place and the cbmem recovery called. This call is added to x86/postcar.c to achieve that. Additionally, one needs to provide postcar stage cbmem init hook callbacks for the cbmem console library to use. A few other places need to become postcar stage aware so that the code paths are taken. Lastly, since postcar is backed by ram indicate that to the cbmem backing store.

2016-08-27cbmem: Always maintain backing store struct in a global on non-x86Julius Werner
The current CBMEM code contains an optimization that maintains the structure with information about the CBMEM backing store in a global variable, so that we don't have to recover it from cbmem_top() again every single time we access CBMEM. However, due to the problems with using globals in x86 romstage, this optimization has only been enabled in ramstage. However, all non-x86 platforms are SRAM-based (at least for now) and can use globals perfectly fine in earlier stages. Therefore, this patch extends the optimization on those platforms to all stages. This also allows us to remove the requirement that cbmem_top() needs to return NULL before its backing store has been initialized from those boards, since the CBMEM code can now keep track of whether it has been initialized by itself.

2015-06-09cbmem: Unify CBMEM init tasks with CBMEM_INIT_HOOK() APIKyösti Mälkki
Squashed and adjusted two changes from chromium.git. Covers CBMEM init for ROMTAGE and RAMSTAGE. cbmem: Unify random on-CBMEM-init tasks under common CBMEM_INIT_HOOK() API There are several use cases for performing a certain task when CBMEM is first set up (usually to migrate some data into it that was previously kept in BSS/SRAM/hammerspace), and unfortunately we handle each of them differently: timestamp migration is called explicitly from cbmem_initialize(), certain x86-chipset-specific tasks use the CAR_MIGRATION() macro to register a hook, and the CBMEM console is migrated through a direct call from romstage (on non-x86 and SandyBridge boards). This patch decouples the CAR_MIGRATION() hook mechanism from cache-as-RAM and rechristens it to CBMEM_INIT_HOOK(), which is a clearer description of what it really does. All of the above use cases are ported to this new, consistent model, allowing us to have one less line of boilerplate in non-CAR romstages.

Oops. This patch fixes the issue by extending the CBMEM_INIT_HOOK() mechanism to the cbmem_initialize() call in ramstage. The macro is split into explicit ROMSTAGE_/RAMSTAGE_ versions to make the behavior as clear as possible and prevent surprises (although just using a single macro and relying on the Makefiles to link an object into all appropriate stages would also work). This allows us to get rid of the explicit cbmemc_reinit() in ramstage (which I somehow accounted for in the last patch without realizing that timestamps work exactly the same way...), and replace the older and less flexible cbmem_arch_init() mechanism. Also added a size assertion for the pre-RAM CBMEM console to memlayout that could prevent a very unlikely buffer overflow I just noticed.

2015-05-26x86: provide consistent cbmem_top() for CONFIG_LATE_CBMEM_INITAaron Durbin
For x86 systems employing CONFIG_LATE_CBMEM_INIT, set_top_of_ram() is called in ramstage to note the upper address of the 32-bit address space. This in turn is consumed by cbmem. However, in this scenario cbmem_top() cannot always be relied upon because get_top_of_ram() doesn't return the same value provided to set_top_of_ram(). To fix the inconsistency in ramstage save the value passed in to set_top_of_ram() and defer to it as the return value for cbmem_top().

1) Save the pointer to the FSP HOB list to low memory at address 0x614. This is the same location as CBMEM_RESUME_BACKUP - the two aren't used in the same platform, so overlapping should be OK. I didn't see any documentation that actually said that this location was free to use, and didn't need to be restored after use in S3 resume, but it looks like the DOS boot vector gets loaded juat above this location, so it SHOULD be ok. The alternative is to copy the memory out and store it in cbmem until we're ready to restore it. 2) When a request for the pointer to a CAR variable comes in, pass back the location inside the FSP hob structure. 3) Skip the memcopy of the CAR Data. The CAR variables do not get transitioned back into cbmem, but used out of the HOB structure. 4) Remove the BROKEN_CAR_MIGRATE Kconfig option from the FSP platform.

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.

This patch adds an option to build the ramstage as a reloctable binary. It uses the rmodule library for the relocation. The main changes consist of the following: 1. The ramstage is loaded just under the cmbem space. 2. Payloads cannot be loaded over where ramstage is loaded. If a payload is attempted to load where the relocatable ramstage resides the load is aborted. 3. The memory occupied by the ramstage is reserved from the OS's usage using the romstage_handoff structure stored in cbmem. This region is communicated to ramstage by an CBMEM_ID_ROMSTAGE_INFO entry in cbmem. 4. There is no need to reserve cbmem space for the OS controlled memory for the resume path because the ramsage region has been reserved in #3. 5. Since no memory needs to be preserved in the wake path, the loading and begin of execution of a elf payload is straight forward.

2013-01-12Implement GCC code coverage analysisStefan Reinauer
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. For a sneak peak of what will expect you, please take a look at http://www.coreboot.org/~stepan/coreboot-coverage/ Change-Id: Ib287d8309878a1f5c4be770c38b1bc0bb3aa6ec7 Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/2052 Tested-by: build bot (Jenkins) Reviewed-by: David Hendricks <dhendrix@chromium.org> Reviewed-by: Martin Roth <martin@se-eng.com> Reviewed-by: Ronald G.

2012-11-14SMM: Restore GNVS pointer in the resume pathDuncan Laurie
The SMM GNVS pointer is normally updated only when the ACPI tables are created, which does not happen in the resume path. In order to restore this pointer it needs to be available at resume time. The method used to locate it at creation time cannot be used again as that magic signature is overwritten with the address itself. So a new CBMEM ID is added to store the 32bit address so it can be found again easily. A new function is defined to save this pointer in CBMEM which needs to be called when the ACPI tables are created in each mainboard when write_acpi_tables() is called. The cpu_index variable had to be renamed due to a conflict when cpu/cpu.h is added for the smm_setup_structures() prototype.

2012-11-12ELOG: Support for non-memory mapped flashDuncan Laurie
If the event log is stored in flash that is not memory mapped then it must use the SPI controller to read from the flash device instead of relying on memory accesses. In addition a new CBMEM ID is added to keep an resident copy of the ELOG around if needed. The use of CBMEM for this is guarded by a new CONFIG_ELOG_CBMEM config option. This CBMEM buffer is created and filled late in the process when the SMBIOS table is being created because CBMEM is not functional when ELOG is first initialized. The downside to using CBMEM is that events added via the SMI handler at runtime are not reflected in the CBMEM copy because I don't want to let the SMM handler write to memory outside the TSEG region. In reality the only time we add runtime events is at kernel shutdown so the impact is limited. Test: 1) Test with CONFIG_ELOG_CBMEM enabled to ensure the event log is operational and SMBIOS points to address in CBMEM. The test should involve at least on reboot to ensure that the kernel is able to write events as well. > mosys -l smbios info log | grep ^address address | 0xacedd000 > mosys eventlog list 0 | 2012-10-10 14:02:46 | Log area cleared | 4096 1 | 2012-10-10 14:02:46 | System boot | 478 2 | 2012-10-10 14:02:46 | System Reset 3 | 2012-10-10 14:03:33 | Kernel Event | Clean Shutdown 4 | 2012-10-10 14:03:34 | System boot | 479 5 | 2012-10-10 14:03:34 | System Reset 2) Test with CONFIG_ELOG_CBMEM disabled to ensure the event log is operational and SMBIOS points to memory mapped flash.

2012-04-06Add constants for fast path resume copyingStefan Reinauer
cache as ram does not usually cache the ram before it is up. Hence, if romstage.c backs up resume memory, the involved memcpy is always uncached. This makes resume very slow. On Sandybridge we copy the memory later, after enabling caching, and that allows us to resume in as little as 250ms.
