ACPICA: Fix GCC 12 dangling-pointer warning

2023-07-10T13:21:03+00:00

ACPICA commit aea0a5cfce262ce2ab16fd96d87c12cf5e756380 We're storing a persistent pointer to an ephemeral local variable which technically is a dangling pointer and the compiler is correct. However, since we never indirect the pointer, this is a safe operation and we can suppress the warning. Also, some C run-times (like MUSL) aren't including indirectly so we must include it explicitly or we won't have the type definition for uintptr_t. Fixes issue #867.

ACPICA: Avoid undefined behavior: member access within null pointer

ACPICA: Use uintptr_t and offsetof() in Linux kernel builds

2022-01-25T17:41:23+00:00

To avoid "performing pointer subtraction with a null pointer has undefined behavior" compiler warnings, use uintptr_t and offsetof() that are always available during Linux kernel builds to define acpi_uintptr_t and the ACPI_TO_INTEGER() and ACPI_OFFSET() macros. Based on earlier proposal from Arnd Bergmann. Link: https://lore.kernel.org/linux-acpi/20210927121338.938994-1-arnd@kernel.org Signed-off-by: Rafael J. Wysocki Reviewed-by: Arnd Bergmann

ACPI: OSL: Make ACPICA use logical addresses of GPE blocks

2020-09-11T14:45:00+00:00

Define ACPI_GPE_USE_LOGICAL_ADDRESSES in aclinux.h and modify acpi_os_initialize() to store the logical addresses of the FADT GPE blocks 0 and 1 in acpi_gbl_xgpe0_block_logical_address and acpi_gbl_xgpe1_block_logical_address, respectively, so as to allow ACPICA to use them for accessing GPE registers in system memory, instead of using their physical addresses and looking up the corresponding logical addresses on every access attempt, which is inefficient.
