I usually test using gnome desktop in the VM, and in this case vaddr is not set, and calling vmap() is needed. (and I don't get the warning, I will check why). >> >> We actually should reject all BOs that don't have bo->base.vaddr set at >> the panic time.

In the panic handler, no other tasks can run in parallel. Also the buffer object is the one currently displayed, so it can't be in the middle of a free/resize or move operation. So I think it's safe to call vmap() from the panic handler. > > Think ideally we need to have a pre-allocated and pre-mapped BO.

WDYT? > This means a full framebuffer will be allocated only for the panic use case. For GPU with a small amount of VRAM, it's not possible. But virtio-gpu is a bit special as it uses system RAM, so it might be less problematic to do that. An alternate solution would be to make sure the framebuffer is vmapped (at least if it's shmem) so the panic handler won't need to call vmap().

No. I intend vbuf_resource_flush to point to a different vbuf than vbuf_dumb_bo. I allocate 2 vbufs in virtio_gpu_plane_init() so that vbuf_dumb_bo points to the first vbuf and vbuf_resource_flush points to the second one. > Won't be using kmem_cache_zalloc(vgdev->vbufs, GFP_ATOMIC) to > dynamically allocate both buffers make everything cleaner? > > ... > > -#define MAX_INLINE_CMD_SIZE 96 > > -#define MAX_INLINE_RESP_SIZE 24 > > -#define VBUFFER_SIZE (sizeof(struct virtio_gpu_vbuffer) \ > > - + MAX_INLINE_CMD_SIZE \ > > - + MAX_INLINE_RESP_SIZE)... > Yes, it is feasible.

Mass-change the DRM framework code to pass const argument to that callback. The series has been compile-tested with defconfig for x86-64, arm and arm64. Note: yes, I understand that this change might be hard to review and merge. The only viable option that I foresee is to add new callback, having the const argument and migrate drivers into using it one by one.
