similar to: [PATCH v2 0/3] drm/nouveau: Add drm_panic support for nv50+

This series adds basic drm_panic support for nouveau. Patches 1 Add ABGR2101010 support in drm_panic. Patch 2 registers nouveau to drm_panic, and handle tiling. I've tested on a GTX1650 (Turing) and GF 8800 GT (Tesla), while running Gnome/Wayland desktop, and in VT. It should work on other nv50+ cards, but I didn't test them. To test it, you need to build your kernel with

The 'w' argument to NVCopyNV12ColorPlanes is used to index into the source image. line_len is rounded up to 8 on NV50+, so if the source image (+ left offset) is not rounded to 8, NVCopyNV12ColorPlanes could read past the end of the array and crash X. This change can cause the last few horizontal pixels of dst to not be initialized, but they should be truncated by the renderer anyways.

Many people using nv50+ hardware are aware of gpu lockups when a fifo closes under certain conditions. Based on a mmio-trace and some trail and error testing i've come up with a patch that improves the situation on my NV96. This patch needs testing on NV50+ hardware and regression testing on older hardware, since i did change some of the common codepaths. This is very much a work in progress,
