firmware: SDEI: Allow sdei initialization without ACPI_APEI_GHES

2025-06-19T13:28:08+00:00

[ Upstream commit 59529bbe642de4eb2191a541d9b4bae7eb73862e ] SDEI usually initialize with the ACPI table, but on platforms where ACPI is not used, the SDEI feature can still be used to handle specific firmware calls or other customized purposes. Therefore, it is not necessary for ARM_SDE_INTERFACE to depend on ACPI_APEI_GHES. In commit dc4e8c07e9e2 ("ACPI: APEI: explicit init of HEST and GHES in acpi_init()"), to make APEI ready earlier, sdei_init was moved into acpi_ghes_init instead of being a standalone initcall, adding ACPI_APEI_GHES dependency to ARM_SDE_INTERFACE. This restricts the flexibility and usability of SDEI. This patch corrects the dependency in Kconfig and splits sdei_init() into two separate functions: sdei_init() and acpi_sdei_init(). sdei_init() will be called by arch_initcall and will only initialize the platform driver, while acpi_sdei_init() will initialize the device from acpi_ghes_init() when ACPI is ready. This allows the initialization of SDEI without ACPI_APEI_GHES enabled.

video: Add helpers for decoding screen_info

2024-08-11T10:47:15+00:00

[ Upstream commit 75fa9b7e375e35739663cde0252d31e586c6314a ] The plain values as stored in struct screen_info need to be decoded before being used. Add helpers that decode the type of video output and the framebuffer I/O aperture. Old or non-x86 systems may not set the type of video directly, but only indicate the presence by storing 0x01 in orig_video_isVGA. The decoding logic in screen_info_video_type() takes this into account. It then follows similar code in vgacon's vgacon_startup() to detect the video type from the given values. A call to screen_info_resources() returns all known resources of the given screen_info. The resources' values have been taken from existing code in vgacon and vga16fb. These drivers can later be converted to use the new interfaces. v2: * return ssize_t from screen_info_resources() * don't call __screen_info_has_lfb() unnecessarily Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20240212090736.11464-2-tzimmermann@suse.de Stable-dep-of: c2bc958b2b03 ("fbdev: vesafb: Detect VGA compatibility from screen info's VESA attributes") Signed-off-by: Sasha Levin

firmware: mediatek: Add adsp ipc protocol interface

2022-05-16T11:58:11+00:00

Some of mediatek processors contain the Tensilica HiFix DSP for audio processing. The communication between Host CPU and DSP firmware is taking place using a shared memory area for message passing. ADSP IPC protocol offers (send/recv) interfaces using mediatek-mailbox APIs. We use two mbox channels to implement a request-reply protocol.

sysfb: Enable boot time VESA graphic mode selection

2022-03-04T19:55:33+00:00

Since switch to simplefb/simpledrm VESA graphic mode selection with vga= kernel parameter is no longer available with legacy BIOS. The x86 realmode boot code enables the VESA graphic modes when option FB_BOOT_VESA_SUPPORT is enabled. This option is selected by vesafb but not simplefb/simpledrm. To enable use of VESA modes with simplefb in legacy BIOS boot mode drop dependency of BOOT_VESA_SUPPORT on FB, also drop the FB_ prefix. Select the option from sysfb rather than the drivers that depend on it. The BOOT_VESA_SUPPORT is not specific to framebuffer but rather to x86 platform, move it from fbdev to x86 Kconfig.

ACPI: APEI: explicit init of HEST and GHES in apci_init()

2022-03-03T19:24:22+00:00

From commit e147133a42cb ("ACPI / APEI: Make hest.c manage the estatus memory pool") was merged, ghes_init() relies on acpi_hest_init() to manage the estatus memory pool. On the other hand, ghes_init() relies on sdei_init() to detect the SDEI version and (un)register events. The dependencies are as follows: ghes_init() => acpi_hest_init() => acpi_bus_init() => acpi_init() ghes_init() => sdei_init() HEST is not PCI-specific and initcall ordering is implicit and not well-defined within a level. Based on above, remove acpi_hest_init() from acpi_pci_root_init() and convert ghes_init() and sdei_init() from initcalls to explicit calls in the following order: acpi_hest_init() ghes_init() sdei_init() Signed-off-by: Shuai Xue Signed-off-by: Rafael J.
