[PATCH v2 1/2] x86/microcode/AMD: Fix __apply_microcode_amd()'s return value

by Boris Ostrovsky

When verify_sha256_digest() fails, __apply_microcode_amd() should propagate the failure by returning false (and not -1 which is promoted to true) Fixes: 50cef76d5cb0 ("x86/microcode/AMD: Load only SHA256-checksummed patches") Cc: stable(a)vger.kernel.org Signed-off-by: Boris Ostrovsky <boris.ostrovsky(a)oracle.com> --- arch/x86/kernel/cpu/microcode/amd.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/x86/kernel/cpu/microcode/amd.c b/arch/x86/kernel/cpu/microcode/amd.c index 138689b8e1d8..b61028cf5c8a 100644 --- a/arch/x86/kernel/cpu/microcode/amd.c +++ b/arch/x86/kernel/cpu/microcode/amd.c @@ -600,7 +600,7 @@ static bool __apply_microcode_amd(struct microcode_amd *mc, u32 *cur_rev, unsigned long p_addr = (unsigned long)&mc->hdr.data_code; if (!verify_sha256_digest(mc->hdr.patch_id, *cur_rev, (const u8 *)p_addr, psize)) - return -1; + return false; native_wrmsrl(MSR_AMD64_PATCH_LOADER, p_addr); -- 2.43.5

[PATCH v2 1/4] drm/cirrus-qemu: Fix pitch programming

by Thomas Zimmermann

Do not set CR1B[6] when programming the pitch. The bit effects VGA text mode and is not interpreted by qemu. [1] It has no affect on the scanline pitch. The scanline bit that is set into CR1B[6] belongs into CR13[7], which the driver sets up correctly. This bug goes back to the driver's initial commit.

[PATCH v1 1/1] mfd: rk8xx: Fix shutdown handler

by Sebastian Reichel

When I converted rk808 to device managed resources I converted the rk808 specific pm_power_off handler to devm_register_sys_off_handler() using SYS_OFF_MODE_POWER_OFF_PREPARE, which is allowed to sleep. I did this because the driver's poweroff function makes use of regmap and the backend of that might sleep. But the PMIC poweroff function will kill off the board power and the kernel does some extra steps after the prepare handler. Thus the prepare handler should not be used for the PMIC's poweroff routine. Instead the normal SYS_OFF_MODE_POWER_OFF phase should be used. The old pm_power_off method is also being called from there, so this would have been a cleaner conversion anyways. But it still makes sense to investigate the sleep handling and check if there are any issues. Apparently the Rockchip and Meson I2C drivers (the only platforms using the PMICs handled by this driver) both have support for atomic transfers and thus may be called from the proper poweroff context. Things are different on the SPI side. That is so far only used by rk806 and that one is only used by Rockchip RK3588. Unfortunately the Rockchip SPI driver does not support atomic transfers. That means using the normal POWER_OFF handler would introduce the following error splash during shutdown on all RK3588 boards currently supported upstream: [ 13.761353] ------------[ cut here ]------------ [ 13.761764] Voluntary context switch within RCU read-side critical section!

[PATCH V3] USB: OHCI: Add quirk for LS7A OHCI controller (rev 0x02)

by Huacai Chen

The OHCI controller (rev 0x02) under LS7A PCI host has a hardware flaw. MMIO register with offset 0x60/0x64 is treated as legacy PS2-compatible keyboard/mouse interface, which confuse the OHCI controller. Since OHCI only use a 4KB BAR resource indeed, the LS7A OHCI controller's 32KB BAR is wrapped around (the second 4KB BAR space is the same as the first 4KB internally). So we can add an 4KB offset (0x1000) to the OHCI registers (from the PCI BAR resource) as a quirk.

[PATCH] spi: fsl-qspi: use devm function instead of driver remove

by Han Xu

Driver use devm APIs to manage clk/irq/resources and register the spi controller, but the legacy remove function will be called first during device detach and trigger kernel panic. Drop the remove function and use devm_add_action_or_reset() for driver cleanup to ensure the release sequence.
