UPSTREAM: soc/intel/alderlake: Add method to determine the cpu type set_cpu_type(): It determines the CPU type (big or small) that is executing the function, and marks the global_cpu_type's array slot which is corresponds to the executing CPU's index if the CPU type is big core. get_cpu_index(): It determines the index from LAPIC Ids. This is required to expose CPPC3 package in ascending order of CPUs' LAPIC ids. So, the function returns CPU's position from the ascending order list of LAPIC ids. TEST=Tested CPU index calculation, core type determination on Brya Change-Id: Iaeb7491c178e574e633ca9048e4230831bce5b86 Signed-off-by: Nick Vaccaro <nvaccaro@google.com> Original-Commit-Id: cd1cd8d1176cf65f189f0346679c3f4e4fe9af92 Original-Signed-off-by: Sridhar Siricilla <sridhar.siricilla@intel.com> Original-Change-Id: If4ceb24d9bb1e808750bf618c29b2b9ea6d4191b Original-Reviewed-on: https://review.coreboot.org/c/coreboot/+/59360 Original-Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Original-Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/third_party/coreboot/+/3403150 Reviewed-by: Kangheui Won <khwon@chromium.org>
coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.
With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.
coreboot was formerly known as LinuxBIOS.
After the basic initialization of the hardware has been performed, any desired “payload” can be started by coreboot.
See https://www.coreboot.org/Payloads for a list of supported payloads.
coreboot supports a wide range of chipsets, devices, and mainboards.
For details please consult:
ANY_TOOLCHAIN Kconfig option if you’re feeling lucky (no support in this case).Optional:
make menuconfig and make nconfig)Please consult https://www.coreboot.org/Build_HOWTO for details.
If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU.
Please see https://www.coreboot.org/QEMU for details.
Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website:
