2025-05-04x86/boot/sev: Support memory acceptance in the EFI stub under SVSMArd Biesheuvel
Commit: d54d610243a4 ("x86/boot/sev: Avoid shared GHCB page for early memory acceptance") provided a fix for SEV-SNP memory acceptance from the EFI stub when running at VMPL #0. However, that fix was insufficient for SVSM SEV-SNP guests running at VMPL >0, as those rely on a SVSM calling area, which is a shared buffer whose address is programmed into a SEV-SNP MSR, and the SEV init code that sets up this calling area executes much later during the boot. Given that booting via the EFI stub at VMPL >0 implies that the firmware has configured this calling area already, reuse it for performing memory acceptance in the EFI stub.

2025-05-02irqchip/qcom-mpm: Prevent crash when trying to handle non-wake GPIOsStephan Gerhold
On Qualcomm chipsets not all GPIOs are wakeup capable. Those GPIOs do not have a corresponding MPM pin and should not be handled inside the MPM driver. The IRQ domain hierarchy is always applied, so it's required to explicitly disconnect the hierarchy for those. The pinctrl-msm driver marks these with GPIO_NO_WAKE_IRQ. qcom-pdc has a check for this, but irq-qcom-mpm is currently missing the check. This is causing crashes when setting up interrupts for non-wake GPIOs: root@rb1:~# gpiomon -c gpiochip1 10 irq: IRQ159: trimming hierarchy from :soc@0:interrupt-controller@f200000-1 Unable to handle kernel paging request at virtual address ffff8000a1dc3820 Hardware name: Qualcomm Technologies, Inc.

2025-05-02drm/i915/hdcp: switch the HDCP GSC message interface from u8* to void*Jani Nikula
The in/out buffers are just opaque data, and don't need to be considered u8*. Switching to void* lets us drop a ton of unnecessary casts.

2025-05-02drm/i915/hdcp: pass the context to the HDCP GSC message interfaceJani Nikula
The opaque HDCP GSC context nicely abstracts the differences between drivers. Pass that instead of struct drm_i915_private or struct xe_device to intel_hdcp_gsc_msg_send(). We can store the driver specific data in the context. This lets us drop the dependency on i915_drv.h from intel_hdcp_gsc_message.c.

2025-05-02drm/i915/hdcp: deduplicate and refactor HDCP GSC ops initializationJani Nikula
The gsc_hdcp_ops is duplicated and initialized exactly the same way in two different places (for i915 and xe), and requires forward declarations for all the hooks. Deduplicate, and make the functions static. There are slight differences in the i915 and xe implementations of intel_hdcp_gsc_init() and intel_hdcp_gsc_fini(). Take the best of both, and improve. We need to expose intel_hdcp_gsc_hdcp2_init() and intel_hdcp_gsc_free_message() for this, and create the latter for xe.

2025-05-02drm/i915/error: drop dmesg suggestion to file bugs on GPU hangsJani Nikula
We haven't updated the DRIVER_TIMESTAMP since commit 3570bd989acc ("drm/i915: Update DRIVER_DATE to 20230929") 1½ years ago. Before then, the previous update was commit 139caf7ca286 ("drm/i915: Update DRIVER_DATE to 20201103") 4+ years ago. The DRIVER_DATE has also been removed altogether. We've used the DRIVER_TIMESTAMP to log suggestions to file bugs on GPU hangs when they happen on a driver less than six months old. Combined with the sporadic DRIVER_TIMESTAMP updates, we really haven't logged the suggestions for years. Just stop logging the suggestion to file bugs altogether, and remove DRIVER_TIMESTAMP. This doesn't really change anything wrt to logging GPU errors or how we handle bugs. And effectively we already stopped logging the message a year ago when we stopped updating DRIVER_TIMESTAMP. Instead, add an unconditional message about the GPU error state location.
