2024-08-30drivers/efi/uefi_capsules.c: coalesce and store UEFI capsulesSergii Dmytruk
How it approximately works: (During a normal system run): 1. OS puts a capsule into RAM and calls UpdateCapsule() function of EFI runtime 2. If applying the update requires a reboot, EFI implementation creates a new CapsuleUpdateData* EFI variable pointing at the beginning of capsules description (not data, but description of the data) and does a warm reboot leaving capsule data and its description in RAM to be picked by firmware on the next boot process (After DEV_INIT:) 3. Capsules are discovered by checking for CapsuleUpdateData* variables 4. Capsule description in memory and capsule data is validated for sanity 5. Capsule data is coalesced into a continuous piece of memory (On BS_WRITE_TABLES via dasharo_add_capsules_to_bootmem() hook:) 6. Buffer with coalesced capsules is marked as reserved (On BS_WRITE_TABLES via lb_uefi_capsules() hook:) 7. coreboot table entry is added for each of the discovered capsules (In UEFI payload:) 8. CapsuleUpdateData* get removed 9. coreboot table is checked for any update capsules which are then applied Change-Id: I162d678ae5c504906084b59c1a8d8c26dadb9433 Signed-off-by: Sergii Dmytruk <sergii.dmytruk@3mdeb.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/83422 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Krystian Hebel <krystian.hebel@3mdeb.com>
2023-03-03lib: set up specific purpose memory as LB_MEM_SOFT_RESERVEDJonathan Zhang
CXL (Compute Express Link) [1] is a cache-coherent interconnect standard for processors, memory expansion and accelerators. CXL memory is provided through CXL device which is connected through CXL/PCIe link, while regular system memory is provided through DIMMs plugged into DIMM slots which are connected to memory controllers of processor. With CXL memory, the server's memory capacity is increased. CXL memory is in its own NUMA domain, with longer latency and added bandwidth, comparing to regular system memory. Host firmware may present CXL memory as specific purpose memory. Linux kernel dax driver provides direct access to such differentiated memory. In particular, hmem dax driver provides direct access to specific purpose memory. Specific purpose memory needs to be represented in e820 table as soft reserved, as described in [2]. Add IORESOURCE_SOFT_RESERVE resource property to indicate (memory) resource that needs to be soft reserved. Add soft_reserved_ram_resource macro to allow soc/mb code to add memory resource as soft reserved.

Now that the console system itself will clearly differentiate loglevels, it is no longer necessary to explicitly add "ERROR: " in front of every BIOS_ERR message to help it stand out more (and allow automated tooling to grep for it).

2019-02-22symbols.h: Add macro to define memlayout region symbolsJulius Werner
When <symbols.h> was first introduced, it only declared a handful of regions and we didn't expect that too many architectures and platforms would need to add their own later. However, our amount of platforms has greatly expanded since, and with them the need for more special memory regions. The amount of code duplication is starting to get unsightly, and platforms keep defining their own <soc/symbols.h> files that need this as well. This patch adds another macro to cut down the definition boilerplate. Unfortunately, macros cannot define other macros when they're called, so referring to region sizes as _name_size doesn't work anymore. This patch replaces the scheme with REGION_SIZE(name). Not touching the regions in the x86-specific <arch/symbols.h> yet since they don't follow the standard _region/_eregion naming scheme. They can be converted later if desired.

2018-10-11selfboot: remove bounce buffersRonald G. Minnich
Bounce buffers used to be used in those cases where the payload might overlap coreboot. Bounce buffers are a problem for rampayloads as they need malloc. They are also an artifact of our x86 past before we had relocatable ramstage; only x86, out of the 5 architectures we support, needs them; currently they only seem to matter on the following chipsets: src/northbridge/amd/amdfam10/Kconfig src/northbridge/amd/lx/Kconfig src/northbridge/via/vx900/Kconfig src/soc/intel/fsp_baytrail/Kconfig src/soc/intel/fsp_broadwell_de/Kconfig The first three are obsolete or at least could be changed to avoid the need to have bounce buffers. The last two should change to no longer need them. In any event they can be fixed or pegged to a release which supports them. For these five chipsets we change CONFIG_RAMBASE from 0x100000 (the value needed in 1999 for the 32-bit Linux kernel, the original ramstage) to 0xe00000 (14 Mib) which will put the non-relocatable x86 ramstage out of the way of any reasonable payload until we can get rid of it for good. 14 MiB was chosen after some discussion, but it does fit well: o Fits in the 16 MiB cacheable range coreboot sets up by default o Most small payloads are well under 14 MiB (even kernels!) o Most large payloads get loaded at 16 MiB (especially kernels!) With this change in place coreboot correctly still loads a bzImage payload. Werner reports that the 0xe00000 setting works on his broadwell systems.

2018-05-10bootmem: Keep OS memory map separate from the startJulius Werner
The patch series ending in 64049be (lib/bootmem: Add method to walk OS POV memory tables) expanded the bootmem framework to also keep track of memory regions that are only relevant while coreboot is still executing, such as the ramstage code and data. Mixing this into the exsting bootmem ranges has already caused an issue on CONFIG_RELOCATEABLE_RAMSTAGE boards, because the ramstage code in CBMEM is marked as BM_RAMSTAGE which ends up getting translated back to LB_RAM in the OS tables. This was fixed in 1ecec5f (lib/bootmem: ensure ramstage memory isn't given to OS) for this specific case, but unfortunately Arm boards can have a similar problem where their stack space is sometimes located in an SRAM region that should not be made available as RAM to the OS. Since both the resources made available to the OS and the regions reserved for coreboot can be different for each platform, we should find a generic solution to this rather than trying to deal with each issue individually. This patch solves the problem by keeping the OS point of view and the coreboot-specific ranges separate from the start, rather than cloning it out later. Ranges only relevant to the coreboot view will never touch the OS-specific layout, to avoid the problem of losing information about the original memory type of the underlying region that needs to be restored for the OS view. This both supersedes the RELOCATABLE_RAMSTAGE fix and resolves the problems on Arm boards.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>
2014-03-03coreboot: introduce notion of bootmem for memory map at bootAaron Durbin
The write_coreboot_table() in coreboot_table.c was already using struct memrange for managing and building up the entries that eventually go into the lb_memory table. Abstract that concept out to a bootmem memory map. The bootmem concept can then be used as a basis for loading payloads, for example.
