* drm-shim: silence warningsLionel Landwerlin2020-04-301-15/+28

* drm-shim: don't create a memfd per BOLionel Landwerlin2020-04-302-13/+30
| | | | | | | | | | | | | | Running shader-db on big servers with many cores, we're running out of file descriptors. Use a single 4Gb memfd instead and allocate from it using a VMA. v2: Align VMA allocation to 4096 (Eric) Signed-off-by: Lionel Landwerlin <[email protected]> Acked-by: Matt Turner <[email protected]> Reviewed-by: Eric Anholt <[email protected]> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/4594>

* drm-shim: Let the driver choose to overwrite the first render node.Eric Anholt2020-04-232-3/+7
| | | | | | | | | | | | | | When I was writing drm-shim, I was focused on the v3d kmsro case -- use my intel device as the kmsro display device and add on a simulator-based v3d device that we could render with. But for the noop backends we use for shader-db, it's a lot more useful to just overwrite the first render node in the system so that you don't have to pass a -d <how many render nodes I already have in my system> argument.

* drm-shim: stub libdrm's use of realpath()Lionel Landwerlin2020-04-031-0/+22
| | | | | | | | | | | libdrm started using realpath to get the type of bus associated with a given device. This stubs the very specific usage that prevents drm-shim's device from being listed.

* v3d: Introduce a DRM shim for calling out to the simulator.Eric Anholt2019-07-255-0/+1022
The goal is to enable testing of parts of drivers without depending on any particular kernel version or hardware being present. Simply set LD_PRELOAD=$PREFIX/lib/libv3d_drm_shim.so in your environment, and we'll fake a /dev/dri/renderD128 (or whatever the next available node is) using v3dv3. That node can then be used with the surfaceless or gbm EGL platforms. Acked-by: Iago Toral Quiroga <[email protected]>
