2025-04-10platform/x86/amd/pmf: Propagate PMF-TA return codesShyam Sundar S K
[ Upstream commit 9ba93cb8212d62bccd8b41b8adb6656abf37280a ] In the amd_pmf_invoke_cmd_init() function within the PMF driver ensure that the actual result from the PMF-TA is returned rather than a generic EIO. This change allows for proper handling of errors originating from the PMF-TA.

2025-01-17platform/x86: intel/pmc: Fix ioremap() of bad addressDavid E. Box
[ Upstream commit 1d7461d0c8330689117286169106af6531a747ed ] In pmc_core_ssram_get_pmc(), the physical addresses for hidden SSRAM devices are retrieved from the MMIO region of the primary SSRAM device. If additional devices are not present, the address returned is zero. Currently, the code does not check for this condition, resulting in ioremap() incorrectly attempting to map address 0. Add a check for a zero address and return 0 if no additional devices are found, as it is not an error for the device to be absent.

commit 032fe9b0516702599c2dd990a4703f783d5716b8 upstream. The HP OMEN 8 (2022), corresponding to a board ID of 8A15, supports OMEN thermal profile and requires the timed profile quirk. Upon adding this ID to both the omen_thermal_profile_boards and omen_timed_thermal_profile_boards, significant bump in performance can be observed. For instance, SilverBench (https://silver.urih.com/) results improved from ~56,000 to ~69,000, as a result of higher power draws (and thus core frequencies) whilst under load: Package Power: - Before the patch: ~65W (dropping to about 55W under sustained load). - After the patch: ~115W (dropping to about 105W under sustained load). Core Power: - Before: ~60W (ditto above). - After: ~108W (ditto above). Add 8A15 to omen_thermal_profile_boards and omen_timed_thermal_profile_boards to improve performance.

2024-12-27p2sb: Do not scan and remove the P2SB device when it is unhiddenShin'ichiro Kawasaki
[ Upstream commit 360c400d0f568636c1b98d1d5f9f49aa3d420c70 ] When drivers access P2SB device resources, it calls p2sb_bar(). Before the commit 5913320eb0b3 ("platform/x86: p2sb: Allow p2sb_bar() calls during PCI device probe"), p2sb_bar() obtained the resources and then called pci_stop_and_remove_bus_device() for clean up. Then the P2SB device disappeared. The commit 5913320eb0b3 introduced the P2SB device resource cache feature in the boot process. During the resource cache, pci_stop_and_remove_bus_device() is called for the P2SB device, then the P2SB device disappears regardless of whether p2sb_bar() is called or not. Such P2SB device disappearance caused a confusion [1]. To avoid the confusion, avoid the pci_stop_and_remove_bus_device() call when the BIOS does not hide the P2SB device. For that purpose, cache the P2SB device resources only if the BIOS hides the P2SB device. Call p2sb_scan_and_cache() only if p2sb_hidden_by_bios is true. This allows removing two branches from p2sb_scan_and_cache(). When p2sb_bar() is called, get the resources from the cache if the P2SB device is hidden. Otherwise, read the resources from the unhidden P2SB device.
