Variant of drm_gem_create_mmap_offset() which doesn't make the assumption that virtual size and physical size (obj->size) are the same. This is needed in omapdrm to deal with tiled buffers. And lets us get rid of a duplicated and slightly modified version of drm_gem_create_mmap_offset() in omapdrm.

And simplify how we hold a ref+pin to what is being scanned out by using fb refcnt'ing. The previous logic pre-dated fb refcnt, and as a result was less straightforward than it could have been. By holding a ref to the fb, we don't have to care about how many plane's there are and holding a ref to each color plane's bo.

Again only used by a tests in libdrm and by dristat. Nowadays we have much better tracing tools to get detailed insights into what a drm driver is doing. And for a simple "does it work" kind of question that these stats could answer we have plenty of dmesg debug log spew. So I don't see any use for this stat gathering complexity at all. To be able to gradually drop things start with ripping out the interfaces to it, here the ioctl. To prevent dristat from eating its own stack garbage we can't use the drm_noop ioctl though, since we need to clear the return data with a memset.

We not only have debugfs files to do pretty much the equivalent of lsof, we also have an ioctl. Not that compared to lsof this dumps a wee bit more information, but we can still get at that from debugfs easily. I've dug around in mesa, libdrm and ddx histories and the only users seem to be drm/tests/dristat.c and drm/tests/getclients.c. The later is a testcase for the ioctl itself since up to commit b018fcda Author: Eric Anholt <eric@anholt.net> Date: Thu Nov 22 18:46:54 2007 +1000 drm: Make DRM_IOCTL_GET_CLIENT return EINVAL when it can't find client #idx there was actually no way at all for userspace to enumerate all clients since the kernel just wouldn't tell it when to stop. Which completely broke it's only user, dristat -c. So obviously that ioctl wasn't much use for debugging. Hence I don't see any point in keeping support for a tool which was pretty obviously never really used, and while we have good replacements in the form of equivalent debugfs files. Still, to keep dristat -c from looping forever again stop it early by returning an unconditional -EINVAL. Also add a comment in the code about why. v2: Slightly less hollowed-out implementation. libva uses GET_CLIENTS to figure out whether the fd it has is already authenticated or not. So we need to keep that part of things working. Simplest way is to just return one entry to keep va_drm_is_authenticated in libva/va/drm/va_drm_auth.c working. This is exercised by igt/drm_get_client_auth which contains a copypasta of the libva auth check code.

They're only used by the agpgart support code in drm_agpgart.c, not by any drivers. I think long-term we should create a drm_internal.h include file with all the various functions only used by the drm core and not exported to drivers, and remove them from drmP.h. Oh, and someone should kill that upper-case P sometimes ;-) But that's all stuff for future patch bombs.

So I've stumbled over drm_fasync and wondered what it does. Digging that up is quite a story. First I've had to read up on what this does and ended up being rather bewildered why peopled loved signals so much back in the days that they've created SIGIO just for that ... Then I wondered how this ever works, and what that strange "No-op." comment right above it should mean. After all calling the core fasync helper is pretty obviously not a noop. After reading through the kernels FASYNC implementation I've noticed that signals are only sent out to the processes attached with FASYNC by calling kill_fasync. No merged drm driver has ever done that. After more digging I've found out that the only driver that ever used this is the so called GAMMA driver. I've frankly never heard of such a gpu brand ever before. Now FASYNC seems to not have been the only bad thing with that driver, since Dave Airlie removed it from the drm driver with prejudice: commit 1430163b4bbf7b00367ea1066c1c5fe85dbeefed Author: Dave Airlie <airlied@linux.ie> Date: Sun Aug 29 12:04:35 2004 +0000 Drop GAMMA DRM from a great height ... Long story short, the drm fasync support seems to be doing absolutely nothing. And the only user of it was never merged into the upstream kernel. And we don't need any fops->fasync callback since the fcntl implementation in the kernel already implements the noop case correctly. So stop this particular cargo-cult and rip it all out. v2: Kill drm_fasync assignments in rcar (newly added) and imx drivers (somehow I've missed that one in staging). Also drop the reference in the drm DocBook. ARM compile-fail reported by Rob Clark. v3: Move the removal of dev->buf_asnyc assignment in drm_setup to this patch here. v4: Actually git add ... tsk.

So after a lot of digging around in git histories it looks like this has only ever be used by dri1 render clients. Hence we can fully disable the entire thing for modesetting drivers and so greatly reduce the attack surface for potential exploits (or at least tools like trinity ...). Also add the drm_legacy prefix for functions which are called from common code. To further reduce the impact on common code also extract all the ctx release handling into a function (instead of only releasing individual handles) and make ctxbitmap_cleanup return void - it can never fail.

Now only legacy ums drivers have the DRIVER_HAVE_DMA driver feature flag set, so strictly speaking the modesetting check is redundant.

When switching between various drivers for this device, it's possible that some critical registers are left containing values which affect the device operation. One such case encountered is the VIP output mux register. This defaults to 0x24 on powerup, but other drivers may set this to 0x12. This results in incorrect colours. Fix this by ensuring that the register is always set to the power on default setting.
