H A D | intel_gvt.h | 5f60b12e Mon Oct 26 23:53:08 CDT 2020 Colin Xu <colin.xu@intel.com> drm/i915/gvt: Save/restore HW status to support GVT suspend/resume
This patch save/restore necessary GVT info during i915 suspend/resume so that GVT enabled QEMU VM can continue running.
Only GGTT and fence regs are saved/restored now. GVT will save GGTT entries on each host_entry update, restore the saved dirty entries and re-init fence regs in resume routine.
V2: - Change kzalloc/kfree to vzalloc/vfree since the space allocated from kmalloc may not enough for all saved GGTT entries. - Keep gvt suspend/resume wrapper in intel_gvt.h/intel_gvt.c and move the actual implementation to gvt.h/gvt.c. (zhenyu) - Check gvt config on and active with intel_gvt_active(). (zhenyu)
V3: (zhenyu) - Incorrect copy length. Should be num entries * entry size. - Use memcpy_toio()/memcpy_fromio() instead of memcpy for iomem. - Add F_PM_SAVE flags to indicate which MMIOs to save/restore for PM.
V4: Rebase.
V5: Fail intel_gvt_save_ggtt as -ENOMEM if fail to alloc memory to save ggtt. Free allocated ggtt_entries on failure.
V6: Save host entry to per-vGPU gtt.ggtt_mm on each host_entry update.
V7: Restore GGTT entry based on present bit. Split fence restore and mmio restore in different functions.
