2025-03-12drm/xe: Fix ring flush invalidationTvrtko Ursulin
Emit_flush_invalidate() is incorrectly marking the write to LRC_PPHWSP as a GGTT write and also writing an atypical ~0 dword as the payload. Fix it. While at it drop the unused flags argument.

2025-03-12drm/xe/rtp: Drop sentinels from arg to xe_rtp_process_to_sr()Lucas De Marchi
There's a mismatch on API: while xe_rtp_process_to_sr() processes entries until an entry without name, the active tracking with xe_rtp_process_ctx_enable_active_tracking() needs to use the number of elements. The number of elements is taken everywhere using ARRAY_SIZE(), but that will have one entry too many. This leads to the following warning, as reported by lkp: drivers/gpu/drm/xe/xe_tuning.c: In function 'xe_tuning_dump': >> include/drm/drm_print.h:228:31: warning: '%s' directive argument is null [-Wformat-overflow=] 228 | drm_printf((printer), "%.*s" fmt, (indent), "\t\t\t\t\tX", ##__VA_ARGS__) | ^~~~~~ drivers/gpu/drm/xe/xe_tuning.c:226:17: note: in expansion of macro 'drm_printf_indent' 226 | drm_printf_indent(p, 1, "%s\n", engine_tunings[idx].name); | ^~~~~~~~~~~~~~~~~ That's because it will still process the last entry when tracking the active tunings. The same issue exists in the WAs. Change xe_rtp_process_to_sr() to also take the number of elements so the empty entry can be removed and the warning should go away. Fixing on the active-tracking side would more fragile as the it would need a `- 1` everywhere and continue to use a different approach for number of elements. Aside from the warning, it's a non-issue as there would always be enough bits allocated and the last entry would never be active since xe_rtp_process_to_sr() stops on the sentinel.

2025-03-12drm/xe/guc_pc: Remove duplicated pc_start callRodrigo Vivi
xe_guc_pc_start() was getting called from both xe_uc_init_hw() and from xe_guc_start(). But both are called from do_gt_restart() and only xe_uc_init_hw() is called at initialization. So, let's remove the duplication in the regular gt_restart path. The only place where xe_guc_pc_start() won't get called now is on the gt_reset failure path. However, if gt_reset has failed, it is really unlikely that the PC start will work or is desired.

Physical address space is 48 bit on Loongson-3A5000 physical machine, however it is 47 bit for VM on Loongson-3A5000 system. Size of physical address space of VM is the same with the size of virtual user space (a half) of physical machine. Variable cpu_vabits represents user address space, kernel address space is not included (user space and kernel space are both a half of total). Here cpu_vabits, rather than cpu_vabits - 1, is to represent the size of guest physical address space. Also there is strict checking about page fault GPA address, inject error if it is larger than maximum GPA address of VM.

On host, the HW guest CSR registers are lost after suspend and resume operation. Since last_vcpu of boot CPU still records latest vCPU pointer so that the guest CSR register skips to reload when boot CPU resumes and vCPU is scheduled. Here last_vcpu is cleared so that guest CSR registers will reload from scheduled vCPU context after suspend and resume.

2025-03-08LoongArch: KVM: Add interrupt checking for AVECBibo Mao
There is a newly added macro INT_AVEC with CSR ESTAT register, which is bit 14 used for LoongArch AVEC support. AVEC interrupt status bit 14 is supported with macro CSR_ESTAT_IS, so here replace the hard-coded value 0x1fff with macro CSR_ESTAT_IS so that the AVEC interrupt status is also supported by KVM.

2025-03-08LoongArch: Use polling play_dead() when resuming from hibernationHuacai Chen
When CONFIG_RANDOM_KMALLOC_CACHES or other randomization infrastructrue enabled, the idle_task's stack may different between the booting kernel and target kernel. So when resuming from hibernation, an ACTION_BOOT_CPU IPI wakeup the idle instruction in arch_cpu_idle_dead() and jump to the interrupt handler. But since the stack pointer is changed, the interrupt handler cannot restore correct context. So rename the current arch_cpu_idle_dead() to idle_play_dead(), make it as the default version of play_dead(), and the new arch_cpu_idle_dead() call play_dead() directly. For hibernation, implement an arch-specific hibernate_resume_nonboot_cpu_disable() to use the polling version (idle instruction is replace by nop, and irq is disabled) of play_dead(), i.e. poll_play_dead(), to avoid IPI handler corrupting the idle_task's stack when resuming from hibernation. This solution is a little similar to commit 406f992e4a372dafbe3c ("x86 / hibernate: Use hlt_play_dead() when resuming from hibernation").
