2011-07-28[media] DocBook: Use base64 for gif/png filesMauro Carvalho Chehab27-17/+2166
The patch utility doesn't work with non-binary files. This causes some tools to break, like generating tarball targets and the scripts that generate diff patches at http://www.kernel.org/pub/linux/kernel/v2.6/. So, let's convert all binaries to ascii using base64, and add a logic at Makefile to convert them back into binaries at runtime.

2011-07-28[media] DocBook/video.xml: Document the remaining data structuresMauro Carvalho Chehab1-2/+45

2011-07-28[media] DocBook/Makefile: Remove osd.h headerMauro Carvalho Chehab2-19/+0
The av7110 uses an OSD API. Such API is not documented at all. Also, the osd.h API uses camelCase and some other weird stuff. Also, dvb-core doesn't recognize it. I don't see any good reason why we should document it. It seems better to just let it as-is. If ever needed, it is probably better to write a different API for dvb-core.

2011-07-28[media] DocBook/net.xml: Synchronize Network data structureMauro Carvalho Chehab2-1/+19
There's no documentation at all for the DVB net API. Still, better to remove a few warnings about the missing symbols. So, add the net data structure inside the net.xml. Now, only the ioctl documentation is missed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-07-28[media] Docbook/ca.xml: match section ID's with the reference linksMauro Carvalho Chehab2-48/+47
Make sure that both ca.h.xml and ca.xml will match the same names for the sections/links. This way, it is now possible to identify API spec gaps: Error: no ID for constraint linkend: ca-pid.

2011-07-28[media] DocBook: Document AUDIO_CONTINUE ioctlMauro Carvalho Chehab1-0/+57

2011-07-28[media] DocBook/dvbproperty.xml: Document the terrestrial delivery systemsMauro Carvalho Chehab1-65/+103

2011-07-28[media] DocBook: Move all media docbook stuff into its own directoryMauro Carvalho Chehab166-720/+275
This patch addresses several issues pointed by Randy Dunlap <rdunlap@xenotime.net> at changeset ece722c: - In the generated index.html file, "media" is listed first, but it should be listed in alphabetical order, not first. - The generated files are (hidden) in .tmpmedia/ - The link from the top-level index.html file to "media" is to media/index.html, but the file is actually in .tmpmedia/media/index.html - Please build docs with and without using "O=builddir" and test that. - Would it be possible for media to have its own Makefile instead of merging into this one? Due to the way cleandocs target works, I had to rename the media DocBook to media_api, otherwise cleandocs would remove the /media directory.

Multiple attempts to dynamically reallocate pci resources have unfortunately lead to regressions.

2011-07-08FS-Cache: Add a helper to bulk uncache pages on an inodeDavid Howells1-0/+16
Add an FS-Cache helper to bulk uncache pages on an inode. This will only work for the circumstance where the pages in the cache correspond 1:1 with the pages attached to an inode's page cache. This is required for CIFS and NFS: When disabling inode cookie, we were returning the cookie and setting cifsi->fscache to NULL but failed to invalidate any previously mapped pages. This resulted in "Bad page state" errors and manifested in other kind of errors when running fsstress. Fix it by uncaching mapped pages when we disable the inode cookie. This patch should fix the following oops and "Bad page state" errors seen during fsstress testing. ------------[ cut here ]------------ kernel BUG at fs/cachefiles/namei.c:201! invalid opcode: 0000 [#1] SMP Pid: 5, comm: kworker/u:0 Not tainted 2.6.38.7-30.fc15.x86_64 #1 Bochs Bochs RIP: 0010: cachefiles_walk_to_object+0x436/0x745 [cachefiles] RSP: 0018:ffff88002ce6dd00 EFLAGS: 00010282 RAX: ffff88002ef165f0 RBX: ffff88001811f500 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 0000000000000100 RDI: 0000000000000282 RBP: ffff88002ce6dda0 R08: 0000000000000100 R09: ffffffff81b3a300 R10: 0000ffff00066c0a R11: 0000000000000003 R12: ffff88002ae54840 R13: ffff88002ae54840 R14: ffff880029c29c00 R15: ffff88001811f4b0 FS: 00007f394dd32720(0000) GS:ffff88002ef00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 00007fffcb62ddf8 CR3: 000000001825f000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process kworker/u:0 (pid: 5, threadinfo ffff88002ce6c000, task ffff88002ce55cc0) Stack: 0000000000000246 ffff88002ce55cc0 ffff88002ce6dd58 ffff88001815dc00 ffff8800185246c0 ffff88001811f618 ffff880029c29d18 ffff88001811f380 ffff88002ce6dd50 ffffffff814757e4 ffff88002ce6dda0 ffffffff8106ac56 Call Trace: cachefiles_lookup_object+0x78/0xd4 [cachefiles] fscache_lookup_object+0x131/0x16d [fscache] fscache_object_work_func+0x1bc/0x669 [fscache] process_one_work+0x186/0x298 worker_thread+0xda/0x15d kthread+0x84/0x8c kernel_thread_helper+0x4/0x10 RIP cachefiles_walk_to_object+0x436/0x745 [cachefiles] ---[ end trace 1d481c9af1804caa ]--- I tested the uncaching by the following means: (1) Create a big file on my NFS server (104857600 bytes).

Radio devices have weird side-effects when used with combined TV/radio tuners and the V4L2 spec is ambiguous on how it should work.
