Fix built-in early-load Intel microcode alignment

2020-01-23T07:22:31Z

commit f5ae2ea6347a308cfe91f53b53682ce635497d0d upstream. Intel Software Developer's Manual, volume 3, chapter 9.11.6 says: "Note that the microcode update must be aligned on a 16-byte boundary and the size of the microcode update must be 1-KByte granular" When early-load Intel microcode is loaded from initramfs, userspace tool 'iucode_tool' has already 16-byte aligned those microcode bits in that initramfs image. Image that was created something like this: iucode_tool --write-earlyfw=FOO.cpio microcode-files... However, when early-load Intel microcode is loaded from built-in firmware BLOB using CONFIG_EXTRA_FIRMWARE= kernel config option, that 16-byte alignment is not guaranteed. Fix this by forcing all built-in firmware BLOBs to 16-byte alignment. [ If we end up having other firmware with much bigger alignment requirements, we might need to introduce some method for the firmware to specify it, this is the minimal "just increase the alignment a bit to account for this one special case" patch - Linus ] Signed-off-by: Jari Ruusu Cc: Borislav Petkov Cc: Fenghua Yu Cc: Luis Chamberlain Cc: stable@kernel.org Signed-off-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman

firmware_loader: Fix labels with comma for builtin firmware

2019-12-31T15:45:39Z

[ Upstream commit 553671b7685972ca671da5f71cf6414b54376e13 ] Some firmware images contain a comma, such as: EXTRA_FIRMWARE "brcm/brcmfmac4334-sdio.samsung,gt-s7710.txt" as Broadcom firmware simply tags the device tree compatible string at the end of the firmware parameter file. And the compatible string contains a comma. This doesn't play well with gas: drivers/base/firmware_loader/builtin/brcm/brcmfmac4334-sdio.samsung,gt-s7710.txt.gen.S: Assembler messages: drivers/base/firmware_loader/builtin/brcm/brcmfmac4334-sdio.samsung,gt-s7710.txt.gen.S:4: Error: bad instruction `_fw_brcm_brcmfmac4334_sdio_samsung,gt_s7710_txt_bin:' drivers/base/firmware_loader/builtin/brcm/brcmfmac4334-sdio.samsung,gt-s7710.txt.gen.S:9: Error: bad instruction `_fw_brcm_brcmfmac4334_sdio_samsung,gt_s7710_txt_name:' drivers/base/firmware_loader/builtin/brcm/brcmfmac4334-sdio.samsung,gt-s7710.txt.gen.S:15: Error: can't resolve `.rodata' {.rodata section} - `_fw_brcm_brcmfmac4334_sdio_samsung' {*UND* section} make[6]: *** [../scripts/Makefile.build:357: drivers/base/firmware_loader/builtin/brcm/brcmfmac4334-sdio.samsung,gt-s7710.txt.gen.o] Error 1 We need to get rid of the comma from the labels used by the assembly stub generator. Replacing a comma using GNU Make subst requires a helper variable.

drivers: base: firmware_loader: add proper SPDX identifiers on files that did not have them.

There were two files in the firmware_loader code that did not have SPDX identifiers on them, so fix that up. Cc: Luis Chamberlain Signed-off-by: Greg Kroah-Hartman

firmware_loader: move firmware/ to drivers/base/firmware_loader/builtin/

2019-01-22T09:23:18Z

Currently, the 'firmware' directory only contains a single Makefile to embed extra firmware into the kernel. Move it to the more relevant place. Signed-off-by: Masahiro Yamada Signed-off-by: Greg Kroah-Hartman
