Not sure what this hook is supposed to do. vmf->vma->vm_private_data should never be NULL, so the extra check in qxl_ttm_fault should have no effect. Drop it.

The ttm_mem_io_* functions are actually internal to TTM and shouldn't be used in a driver. Instead call the qxl_ttm_io_mem_reserve() function directly.

From: Colin Ian King <colin.king at canonical.com> Simply mmap'ing /dev/dri/card0 repeatedly will spam the kernel log with qxl_mmap information messages. The following example code illustrates this: int main(void) { int fd = open("/dev/dri/card0", O_RDONLY); if (fd == -1) err(1, "open failed"); for (;;) { void *m = mmap(NULL, 4096, PROT_READ, MAP_SHARED,

Three^W Two of the TTM drivers intercept the pagefault handler in a rather un-Linuxy and racy way. If they really must intercept the fault call (and it's not clear to me that they need to), I'd rather see them do it like this. The QXL driver seems least likely to need it; as the virtio driver has exactly the same code in it, only commented out. The radeon driver takes its own lock ...

This allows to drop qxl_mode_dumb_mmap() and qxl_bo_mmap_offset(), the default gem function works just fine.
