Our vGPU doesn't have a device ROM, we need follow the PCI spec to report this info to drivers. Otherwise, we would see below errors. Inspecting possible rom at 0xfe049000 (vd=8086:1912 bdf=00:10.0) qemu-system-x86_64: vfio-pci: Cannot read device rom at 00000000-0000-0000-0000-000000000001 Device option ROM contents are probably invalid (check dmesg). Skip option ROM probe with rombar=0, or load from file with romfile=No option rom signature (got 4860) I will also send a improvement patch to PCI subsystem related to PCI ROM. But no idea to omit below error, since no pattern to detect vbios shadow without touch its content. 0000:00:10.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0x0000 Signed-off-by: NChangbin Du <changbin.du@intel.com> Signed-off-by: NZhenyu Wang <zhenyuw@linux.intel.com>

This new debugfs entry is used to figure out which registers of vGPU is different to host. It is a useful tool for new platform enabling and debugging. When read this entry, all the diff mmio are recognized and sorted by mmio offset. Besides, the bit positions of different value are listed in 'Diff' column.

The engine provides a mirror of the CSB and CSB write pointer in the HWSP. Read these status from virtual HWSP in VM can reduce CPU utilization while applications have much more short GPU workloads. Here we update the corresponding data in virtual HWSP as it in virtual MMIO. Before read these status from HWSP in GVT-g VM, please ensure the host support it by checking the BIT(3) of caps in PVINFO. Virtual HWSP only support GEN8+ platform, since the HWSP MMIO may change follow the platform update, please add the corresponding MMIO emulation when enable new platforms in GVT-g. v3 : Add address audit in HWSP address update. v4 : Separate this patch with enalbe virtual HWSP in VM. Use intel_gvt_render_mmio_to_ring_id() to determine ring_id by offset. v5 : Remove unnessary check about Gen8, GVT-g only support Gen8+.

We need debugfs entry to expose some debug information of gvt and vGPUs. The first tool will be added is mmio-diff, which help to find the difference values of host and vGPU mmio. It's useful for platform enabling. This patch just add a basic debugfs infrastructure, each vGPU has its own sub-folder.

Generally, there are 3 types of errors during command scan: a) some commands might be unknown with EBADRQC; b) some cmd access invalid address with EFAULT; c) some unexpected force nonpriv cmd with EPERM. later the healthy state can be judged through the return error. v2: - remove some internal i915 errors rating. (Zhenyu) v3: - the healthy state is judged through the internal defined return error. (Zhenyu) - force non priv cmd error can be ignored.

Theoretically, the largest bulk of commands in the ring buffer of an engine might be the first submission, which usually contains a lot of commands to initialize the HW. After removing the initial allocation of the ring scan buffer and let krealloc() do everything we need, we still have a big chance to get the buffer of suitable size in the first submission.
