Hi all, I've figured that it's again time for a bit of (late) drm spring cleanup. This series here consists of a pile of "rip old stuff out" patches interleaved with "disable old cruft for kms drivers and hide it better". Comments, flames and review highly welcome. I'd be especially happy if the arm guys could check whether I haven't badly broken their drivers - compile-testing arm is a pita, so I haven't yet done that. There's a few driver-wide patches included, but the more invasive ones (i.e. changing more than the drm driver vtable) are split out per-driver for easier merging. If no one screams my plan is to rebase this pile on top of -rc1, give it some more testing (check arm, ugh) and then send a pull request to Dave. That should reduce interference with ongoing driver work as much as possible I hope. My drm cruft todo list still has a pile of ideas, but I've figured I need to stop now for 3.12. For those interested further cleanups could include: - setversion/set_busid: All drm core version 1.1 is legacy cruft, kms drivers should never run in this mode. We could clean up the setversion ioclt (and move the drm core version handling into a legacy function) and set up the bus id unconditionally at driver load time. - There's a few more legacy ioctls/subsystems that could be blocked out for kms drivers (but the required git history digging tends to be tedious). Also I think we could more aggressively move legacy cruft setup/teardown code out-of-line from the main code by extracting it into drm_legacy_ functions (like this series here already does for the context and dma stuff). - I think creating a drm_internal.h header for functions not exported to drivers would be useful. That way we could move all the legacy functions out of drmP.h (which are a lot of them), which should make it much clearer what the real drm driver interface actually is. - drm_os_linux.h should just die in fire. - There's a pile of needless indirection around our agp handling, we duplicate the agp core's CONFIG_AGP=n no-oping function handling in large parts, among other stuff. - The drm coherent dma alloc helpers could get ripped out, at least for kms drivers. For ums drivers there's some funny cases where this mapping is exchanged with userspace for e.g. register access. In a least one case (i810.ko) userspace even sets up that mapping, which allows it to crash the kernel at will (since those maps aren't refcounted). Maybe we need to shovel those interfaces into a drm_legacy.ko module to keep them around but make sure that no new driver even thinks about using them. - There's also the matter of the vblank support code, imo that should be split int a ums and a kms part. That'd would allow us to use struct drm_crtc * in interfaces and proper locking (by grabbing crtc->mutex to exclude races with dpms/modesets). If anyone wants to dig around in those areas please poke me.
