Hello! I'm writing to report a crash in the QXL / DRM code in the Linux kernel. I originally filed the issue on LaunchPad and more details can be found there, although I doubt whether these details are useful. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813620 I first experienced these issues with: * Ubuntu 18.04 (probably kernel 4.15.something) * Ubuntu 18.10 (kernel

Track which bo is used as primary surface. With that in place we don't need the primary_created flag any more, we can just check the primary bo pointer instead. Also verify we don't already have a primary surface in qxl_io_create_primary().

These days drm core checks function pointers everywhere before calling them. So we can drop a bunch of dummy functions now.

The shadow bo is used as qxl surface, so allocate it as QXL_GEM_DOMAIN_SURFACE. Should usually be allocated in PRIV ttm domain then, so this reduces VRAM memory pressure.

qdev->monitors_config->max_allowed is effectively set by the qxl.num_heads module parameter, stored in the qxl_num_crtc variable. Lets get rid of the indirection and use the variable qxl_num_crtc directly. The kernel doesn't need to dereference pointers each time it needs the value, and when reading the code you don't have to trace where and why

The qxl driver uses an empty implementation for its encoder. Replace the code with the generic simple encoder.

This explains it. thanks for looking into it, Gerd

When reading the monitor config fails, don't retry forever. If it fails ten times in a row just give up to avoid the driver hangs. Also add a small delay after each attempt, so the host has a chance to complete a partial update.
