The old table is most definitely wrong. All applications and all drivers that I have ever tested follow the corrected table. Furthermore, that's what all applications expect as well. Any drivers that do not follow the corrected table are broken and should be fixed. This patch drops the old table and replaces it with the corrected table. This should prevent a lot of confusion.

Updates for the "Tuners and Modulators", "Video Standards" and "Digital Video (DV) Timings" sections. Besides lots of trivial little fixes the main changes are: - Remove two footnotes from "Video Standards": the first is a discussion of alternative methods of setting standards, which is pretty pointless since the standards API is effectively frozen anyway, and the second points to 'rationale' that makes little or no sense to me. - Clarify a few things in the "Digital Video (DV) Timings" section. It was awkwardly formatted as well: there used to be a list with multiple bullets that has been reduced to a single item, so drop the list and rewrite that text.

There are already video output drivers that allow STREAMON without any buffers queued, and with the change in vb2 there are now more drivers like that. So saying "The ioctl will succeed only when at least one output buffer is in the incoming queue." isn't true. Just drop the word 'only'. We cannot say that it will also work if no output buffers are queued as long as not all drivers are converted to vb2.

With the previous changes, sysfs regular file code is ready to handle bin files too. This patch makes bin files share the regular file path. * sysfs_create/remove_bin_file() are moved to fs/sysfs/file.c. * sysfs_init_inode() is updated to use the new sysfs_bin_operations instead of bin_fops for bin files. * fs/sysfs/bin.c and the related pieces are removed. This patch shouldn't introduce any behavior difference to bin file accesses. Overall, this unification reduces the amount of duplicate logic, makes behaviors more consistent and paves the road for building simpler and more versatile interface which will allow other subsystems to make use of sysfs for their pseudo filesystems. v2: Stale fs/sysfs/bin.c reference dropped from Documentation/DocBook/filesystems.tmpl.

NAND_BBT_SCANEMPTY is a strange, badly-supported option with omap as its single remaining user. NAND_BBT_SCANEMPTY was likely used by accident in omap2[1]. And anyway, omap2 doesn't scan the chip for bad blocks (courtesy of NAND_SKIP_BBTSCAN), and so its use of this option is irrelevant. This patch drops the NAND_BBT_SCANEMPTY option.

由 David Herrmann 提交于
Render nodes provide an API for userspace to use non-privileged GPU commands without any running DRM-Master. It is useful for offscreen rendering, GPGPU clients, and normal render clients which do not perform modesetting. Compared to legacy clients, render clients no longer need any authentication to perform client ioctls. Instead, user-space controls render/client access to GPUs via filesystem access-modes on the render-node. Once a render-node was opened, a client has full access to the client/render operations on the GPU. However, no modesetting or ioctls that affect global state are allowed on render nodes. To prevent privilege-escalation, drivers must explicitly state that they support render nodes. They must mark their render-only ioctls as DRM_RENDER_ALLOW so render clients can use them. Furthermore, they must support clients without any attached master. If filesystem access-modes are not enough for fine-grained access control to render nodes (very unlikely, considering the versaitlity of FS-ACLs), you may still fall-back to fd-passing from server to client (which allows arbitrary access-control). However, note that revoking access is currently impossible and unlikely to get implemented. Note: Render clients no longer have any associated DRM-Master as they are supposed to be independent of any server state. DRM core highly depends on file_priv->master to be non-NULL for modesetting/ctx/etc. commands. Therefore, drivers must be very careful to not require DRM-Master if they support DRIVER_RENDER. So far render-nodes are protected by "drm_rnodes". As long as this module-parameter is not set to 1, a driver will not create render nodes. This allows us to experiment with the API a bit before we stabilize it. v2: drop insecure GEM_FLINK to force use of dmabuf Signed-off-by: NDavid Herrmann <dh.herrmann@gmail.com> Signed-off-by: NDave Airlie <airlied@redhat.com>

It has way too much potential for driver writers to do stupid things like delayed hw setup because the load sequence is somehow racy (e.g. the imx driver in staging). So don't call it for modesetting drivers, which reduces the complexity of the drm core -> driver interface a notch. v2: Don't forget to update DocBook. v3: Go with Laurent's slightly more elaborate proposal for the DocBook update. Add a few words on top of his diff to elaborate a bit on what KMS drivers should and shouldn't do in lastclose. There was already a paragraph present talking about restoring properties, I've simply extended that one.

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.
