* drm: remove symlinks from build, use Kbuild files for lib buildBen Skeggs2015-01-191-142/+0
| | | | | | | | | | | | | | | | | The DRM build used a separate, symlinked, source tree out of a desire to avoid Kbuild/autotools' object files conflicting. Not only is this very annoying to maintain, but it's made worse by having two entirely separate source file lists to maintain too. Fixes both these issues by ditching automake (it doesn't approve of the kernel's Kbuild syntax) in favour of custom makefiles that can build libnvif.so from the Kbuild files. Like the previous commit, this will never show up in the kernel tree (it has its own version). Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* core: rework event interfaceBen Skeggs2014-08-101-0/+1
| | | | | | | | | | | | | | | This is a lot of prep-work for being able to send event notifications back to userspace. Events now contain data, rather than a "something just happened" signal. Handler data is now embedded into a containing structure, rather than being kmalloc()'d, and can optionally have the notify routine handled in a workqueue. Various races between suspend/unload with display HPD/DP IRQ handlers automagically solved as a result. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* disp/nv50-: move DP link training to core and train from supervisorBen Skeggs2013-02-201-11/+1
| | | | | | | | | | | | | | | We need to be able to do link training for PIOR-connected ANX9805 from the third supervisor handler (due to script ordering in the bios, can't have the "user" call train because some settings are overwritten from the modesetting bios scripts). This moves link training for SOR-connected DP encoders to the second supervisor interrupt, *before* we call the modesetting scripts (yes, different ordering from PIOR is necessary). This is useful since we should now be able to remove some hacks to workaround races between the supervisor and link training paths. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* initial import of nouveau kernel module core, some simple tools, and drmBen Skeggs2013-01-091-0/+109
Ignore (or, if you're really keen, fix) any of the horrors that are part of the emulate-linux-on-libpciaccess (lib/) layer. When I started down this path I was only aiming to prototype the reworked driver core, and never actually intended on going quite this far with things, but it turns out that being able to develop and test the nouveau core from userspace is *very* useful. This tree is based on the code available as of Linux 3.8-rc2. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
