[PATCH] drm/i915/skl+: Disable DC states on DSI ports

by Imre Deak

DC*co/5/6 is not supported on DSI ports active in video mode (Bspec 4234, 49193). On GLK for DSI command mode the "Enter/Exit Low Power Mode" sequence would need to be programmed around each frame update (Bspec 21356) and presumedly the same is required on BXT and SKL, even though it's not stated for those explicitly (BXT: Bspec 13756). The driver doesn't run these sequences, but command mode on BXT-GLK is not implemented either. On ICL+ for DSI command mode DC*co/DSI is supported by the HW (… [View More]Bspec 49195), but this is not implemented in the driver. Based on the above disable DC states while DSI ports are active.

Soon after, sev_es_validate_vmgexit() fetches the exit code again. Since the GHCB page is shared with the guest, the guest is able to quickly swap the values with another vCPU and hence bypass the validation. One vmexit code that can be rejected by sev_es_validate_vmgexit() is SVM_EXIT_VMGEXIT; if sev_handle_vmgexit() observes it in the second fetch, the call to svm_invoke_exit_handler() will invoke sev_handle_vmgexit() again recursively. To avoid the race, always fetch the GHCB data from the places where sev_es_sync_from_ghcb stores it. Exploiting recursions on linux kernel has been proven feasible in the past, but the impact is mitigated by stack guard pages (CONFIG_VMAP_STACK). Still, if an attacker manages to call the handler multiple times, they can theoretically trigger a stack overflow and cause a denial-of-service, or potentially guest-to-host escape in kernel configurations without stack guard pages. Note that winning the race reliably in every iteration is very tricky due to the very tight window of the fetches; depending on the compiler settings, they are often consecutive because of optimization and inlining. Tested by booting an SEV-ES RHEL9 guest.
