| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The memory attributes attached to memory regions depend on architecture specific mappings. For some memory regions, the attributes specified by firmware (eg uncached) are not sufficient to determine how a memory region should be mapped by an OS (for instance a region that is define as uncached in firmware can be mapped as Normal or Device memory on arm64) and therefore the OS must be given control on how to map the region to match the expected mapping behaviour (eg if a mapping is requested with memory semantics, it must allow unaligned accesses). Rework acpi_os_map_memory() and acpi_os_ioremap() back-end to split them into two separate code paths: acpi_os_memmap() -> memory semantics acpi_os_ioremap() -> MMIO semantics The split allows the architectural implementation back-ends to detect the default memory attributes required by the mapping in question (ie the mapping API defines the semantics memory vs MMIO) and map the memory accordingly.

* ACPI: fix NULL pointer dereferenceLinus Torvalds2021-07-241-1/+2
| | | | | | | | | | | | | | | | | Commit 71f642833284 ("ACPI: utils: Fix reference counting in for_each_acpi_dev_match()") started doing "acpi_dev_put()" on a pointer that was possibly NULL. That fails miserably, because that helper inline function is not set up to handle that case. Just make acpi_dev_put() silently accept a NULL pointer, rather than calling down to put_device() with an invalid offset off that NULL pointer.

| | | | | | | | | | | | | | Currently it's possible to iterate over the dangling pointer in case the device suddenly disappears. This may happen becase callers put it at the end of a loop.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ACPICA commit b5e6bcf69dbb9877481992d5ce86008cfb94f5b8 SVKL (Storage Volume Key Location Table) is used by BIOS/Firmware to share storage volume encryption key's with OS. It will be used by userspace to decrypt and mount encrypted drives. So add SVKL table signature and add it to known signatures array support SVKL. You can find details about the SVKL table in TDX specfication titled "Guest-Host-Communication Interface (GHCI) for Intel Trust Domain Extensions (Intel® TDX)", sec 4.4 and in ACPI specification r6.4, sec 5.2.6.

Special configuration (either kernel command line or sysfs-based) is needed to see the messages printed by them and the format of those messages is also special and convoluted. For this reason, replace all of the ACPI_DEBUG_PRINT() and ACPI_EXCEPTION() instances in the ACPI processor driver with corresponding dev_*(), acpi_handle_*() and pr_*() calls depending on the context in which they appear. Also drop the ACPI_PROCESSOR_COMPONENT definition that is not going to be necessary any more. Signed-off-by: Rafael J.
