| * efi: ia64: disable the capsule loaderArd Biesheuvel2020-12-142-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | EFI capsule loading is a feature that was introduced into EFI long after its initial introduction on Itanium, and it is highly unlikely that IA64 systems are receiving firmware updates in the first place, let alone using EFI capsules. So let's disable capsule support altogether on IA64. This fixes a build error on IA64 due to a recent change that added an unconditional include of asm/efi.h, which IA64 does not provide. While at it, tweak the make rules a bit so that the EFI capsule component that is always builtin (even if the EFI capsule loader itself is built as a module) is omitted for all architectures if the module is not enabled in the build.

| * efi: stub: get rid of efi_get_max_fdt_addr()Ard Biesheuvel2020-12-093-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | Now that ARM started following the example of arm64 and RISC-V, and no longer imposes any restrictions on the placement of the FDT in memory at boot, we no longer need per-arch implementations of efi_get_max_fdt_addr() to factor out the differences. So get rid of it. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Atish Patra <atish.patra@wdc.com> Link: https://lore.kernel.org/r/20201029134901.9773-1-ardb@kernel.org
| * efi/efi_test: read RuntimeServicesSupportedHeinrich Schuchardt2020-12-092-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the UEFI 2.8A specification the UEFI enabled firmware provides a configuration table EFI_RT_PROPERTIES_TABLE which indicates which runtime services are enabled. The EFI stub reads this table and saves the value of the field RuntimeServicesSupported internally. The Firmware Test Suite requires the value to determine if UEFI runtime services are correctly implemented. With this patch an IOCTL call is provided to read the value of the field RuntimeServicesSupported, e.g. #define EFI_RUNTIME_GET_SUPPORTED_MASK \ _IOR('p', 0x0C, unsigned int) unsigned int mask; fd = open("/dev/efi_test", O_RDWR); ret = ioctl(fd, EFI_RUNTIME_GET_SUPPORTED_MASK, &mask); Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Link: https://lore.kernel.org/r/20201127192051.1430-1-xypron.glpk@gmx.de Acked-by: Colin Ian King <colin.king@canonical.com> Acked-by: Ivan Hu <ivan.hu@canonical.com> Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
| * efi: capsule: clean scatter-gather entries from the D-cacheArd Biesheuvel2020-12-091-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | Scatter-gather lists passed to UpdateCapsule() should be cleaned from the D-cache to ensure that they are visible to the CPU after a warm reboot before the MMU is enabled. On ARM and arm64 systems, this implies a D-cache clean by virtual address to the point of coherency. However, due to the fact that the firmware itself is not able to map physical addresses back to virtual addresses when running under the OS, this must be done by the caller.

| * efi: capsule: use atomic kmap for transient sglist mappingsArd Biesheuvel2020-12-071-2/+2
| | | | | | | | | | | | | | | | | | Don't use the heavy-weight kmap() API to create short-lived mappings of the scatter-gather list entries that are released as soon as the entries are written. Instead, use kmap_atomic(), which is more suited to this purpose. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
| * efi: x86/xen: switch to efi_get_secureboot_mode helperArd Biesheuvel2020-11-171-3/+0

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Generalize the efi_get_secureboot() function so not only efistub but also other subsystems can use it. Note that the MokSbState handling is not factored out: the variable is boot time only, and so it cannot be parameterized as easily. Also, the IMA code will switch to this version in a future patch, and it does not incorporate the MokSbState exception in the first place. Note that the new efi_get_secureboot_mode() helper treats any failures to read SetupMode as setup mode being disabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | EFI_GENERIC_STUB_INITRD_CMDLINE_LOADER is deprecated, so it should not be enabled by default. In light of commit 4da0b2b7e67524cc ("efi/libstub: Re-enable command line initrd loading for x86"), keep the default for X86.

| * efi/x86: Only copy the compressed kernel image in efi_relocate_kernel()Arvind Sankar2020-10-261-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The image_size argument to efi_relocate_kernel() is currently specified as init_size, but this is unnecessarily large. The compressed kernel is much smaller, in fact, its image only extends up to the start of _bss, since at this point, the .bss section is still uninitialized. Depending on compression level, this can reduce the amount of data copied by 4-5x.

For this we export the following functions: - imx_dsp_request_channel, gets a channel with a given index - imx_dsp_free_channel, frees a channel with a given index Notice that we still request channels at probe to support devices that do not have PM callbacks implemented. More explanations about why requesting a channel has an effect on power savings: - requesting an mailbox channel will call mailbox's startup function. - startup function calls pm_runtime_get_sync which increments device usage count and will keep the device active. Specifically, mailbox clock will be always ON when a mailbox channel is requested.
