2013-08-30OMAPDSS: rename omap_dss_device's 'device' field to 'dst'Tomi Valkeinen
In the old panel device model we had omap_dss_output entities, representing the encoders in the DSS block. This entity had "device" field, which pointed to the panel that was using the omap_dss_output. With the new panel device model, the omap_dss_output is integrated into omap_dss_device, which now represents a "display entity". Thus the "device" field, now in omap_dss_device, points to the next entity in the display entity-chain. This patch renames the "device" field to "dst", which much better tells what the field points to. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Reviewed-by: Archit Taneja <archit@ti.com>
2013-08-30OMAPDSS: rename omap_dss_device's 'output' to 'src'Tomi Valkeinen
In the old panel device model we had "outputs", which were the encoders inside OMAP DSS block, and panel devices (omap_dss_device). The panel devices had a reference to the source of the video data, i.e. reference to an "output", in a field named "output". That was somewhat confusing even in the old panel device model, but even more so with the panel device model where we can have longer chains of display entities. This patch renames the "output" field to "src", which much better tells what the field points to. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Reviewed-by: Archit Taneja <archit@ti.com>

2013-08-29drivers:net: Convert dma_alloc_coherent(...__GFP_ZERO) to dma_zalloc_coherentJoe Perches
__GFP_ZERO is an uncommon flag and perhaps is better not used. static inline dma_zalloc_coherent exists so convert the uses of dma_alloc_coherent with __GFP_ZERO to the more common kernel style with zalloc. Remove memset from the static inline dma_zalloc_coherent and add just one use of __GFP_ZERO instead. Trivially reduces the size of the existing uses of dma_zalloc_coherent.

2013-08-29pkt_sched: fq: Fair Queue packet schedulerEric Dumazet
- Uses perfect flow match (not stochastic hash like SFQ/FQ_codel) - Uses the new_flow/old_flow separation from FQ_codel - New flows get an initial credit allowing IW10 without added delay. - Special FIFO queue for high prio packets (no need for PRIO + FQ) - Uses a hash table of RB trees to locate the flows at enqueue() time - Smart on demand gc (at enqueue() time, RB tree lookup evicts old unused flows) - Dynamic memory allocations. - Designed to allow millions of concurrent flows per Qdisc. - Small memory footprint : ~8K per Qdisc, and 104 bytes per flow. - Single high resolution timer for throttled flows (if any). - One RB tree to link throttled flows. - Ability to have a max rate per flow. We might add a socket option to add per socket limitation. Attempts have been made to add TCP pacing in TCP stack, but this seems to add complex code to an already complex stack. TCP pacing is welcomed for flows having idle times, as the cwnd permits TCP stack to queue a possibly large number of packets. This removes the 'slow start after idle' choice, hitting badly large BDP flows, and applications delivering chunks of data as video streams. Nicely spaced packets : Here interface is 10Gbit, but flow bottleneck is ~20Mbit cwin is big, yet FQ avoids the typical bursts generated by TCP (as in netperf TCP_RR -- -r 100000,100000) 15:01:23.545279 IP A > B: . 78193:81089(2896) ack 65248 win 3125 <nop,nop,timestamp 1115 11597805> 15:01:23.545394 IP B > A: . ack 81089 win 3668 <nop,nop,timestamp 11597985 1115> 15:01:23.546488 IP A > B: . 81089:83985(2896) ack 65248 win 3125 <nop,nop,timestamp 1115 11597805> 15:01:23.546565 IP B > A: . ack 83985 win 3668 <nop,nop,timestamp 11597986 1115> 15:01:23.547713 IP A > B: . 83985:86881(2896) ack 65248 win 3125 <nop,nop,timestamp 1115 11597805> 15:01:23.547778 IP B > A: . ack 86881 win 3668 <nop,nop,timestamp 11597987 1115> 15:01:23.548911 IP A > B: . 86881:89777(2896) ack 65248 win 3125 <nop,nop,timestamp 1115 11597805> 15:01:23.548949 IP B > A: . ack 89777 win 3668 <nop,nop,timestamp 11597988 1115> 15:01:23.550116 IP A > B: . 89777:92673(2896) ack 65248 win 3125 <nop,nop,timestamp 1115 11597805> 15:01:23.550182 IP B > A: . ack 92673 win 3668 <nop,nop,timestamp 11597989 1115> 15:01:23.551333 IP A > B: . 92673:95569(2896) ack 65248 win 3125 <nop,nop,timestamp 1115 11597805> 15:01:23.551406 IP B > A: . ack 95569 win 3668 <nop,nop,timestamp 11597991 1115> 15:01:23.552539 IP A > B: . 95569:98465(2896) ack 65248 win 3125 <nop,nop,timestamp 1115 11597805> 15:01:23.552576 IP B > A: . ack 98465 win 3668 <nop,nop,timestamp 11597992 1115> 15:01:23.553756 IP A > B: . 98465:99913(1448) ack 65248 win 3125 <nop,nop,timestamp 1115 11597805> 15:01:23.554138 IP A > B: P 99913:100001(88) ack 65248 win 3125 <nop,nop,timestamp 1115 11597805> 15:01:23.554204 IP B > A: . ack 100001 win 3668 <nop,nop,timestamp 11597993 1115> 15:01:23.554234 IP B > A: . 65248:68144(2896) ack 100001 win 3668 <nop,nop,timestamp 11597993 1115> 15:01:23.555620 IP B > A: . 68144:71040(2896) ack 100001 win 3668 <nop,nop,timestamp 11597993 1115> 15:01:23.557005 IP B > A: . 71040:73936(2896) ack 100001 win 3668 <nop,nop,timestamp 11597993 1115> 15:01:23.558390 IP B > A: . 73936:76832(2896) ack 100001 win 3668 <nop,nop,timestamp 11597993 1115> 15:01:23.559773 IP B > A: . 76832:79728(2896) ack 100001 win 3668 <nop,nop,timestamp 11597993 1115> 15:01:23.561158 IP B > A: . 79728:82624(2896) ack 100001 win 3668 <nop,nop,timestamp 11597994 1115> 15:01:23.562543 IP B > A: . 82624:85520(2896) ack 100001 win 3668 <nop,nop,timestamp 11597994 1115> 15:01:23.563928 IP B > A: . 85520:88416(2896) ack 100001 win 3668 <nop,nop,timestamp 11597994 1115> 15:01:23.565313 IP B > A: . 88416:91312(2896) ack 100001 win 3668 <nop,nop,timestamp 11597994 1115> 15:01:23.566698 IP B > A: . 91312:94208(2896) ack 100001 win 3668 <nop,nop,timestamp 11597994 1115> 15:01:23.568083 IP B > A: . 94208:97104(2896) ack 100001 win 3668 <nop,nop,timestamp 11597994 1115> 15:01:23.569467 IP B > A: . 97104:100000(2896) ack 100001 win 3668 <nop,nop,timestamp 11597994 1115> 15:01:23.570852 IP B > A: . 100000:102896(2896) ack 100001 win 3668 <nop,nop,timestamp 11597994 1115> 15:01:23.572237 IP B > A: . 102896:105792(2896) ack 100001 win 3668 <nop,nop,timestamp 11597994 1115> 15:01:23.573639 IP B > A: . 105792:108688(2896) ack 100001 win 3668 <nop,nop,timestamp 11597994 1115> 15:01:23.575024 IP B > A: . 108688:111584(2896) ack 100001 win 3668 <nop,nop,timestamp 11597994 1115> 15:01:23.576408 IP B > A: . 111584:114480(2896) ack 100001 win 3668 <nop,nop,timestamp 11597994 1115> 15:01:23.577793 IP B > A: . 114480:117376(2896) ack 100001 win 3668 <nop,nop,timestamp 11597994 1115> TCP timestamps show that most packets from B were queued in the same ms timeframe (TSval 1159799{3,4}), but FQ managed to send them right in time to avoid a big burst.

2013-08-30ARM: shmobile: r8a7779: Update early timer initialisation orderSimon Horman
a894fcc2d01a89e6fe3da0845a4d80a5312e1124 ("ARM: smp_twd: Divorce smp_twd from local timer API") altered twd_local_timer_common_register() so that it may make use of late_timer_init. This is problematic on marzen with Magnus's recent patch "ARM: shmobile: marzen: Switch to DT_MACHINE_START" which switches marzen around to enable USE_OF and thus shmobile_timer_init(), which is registered as late_time_init by shmobile_earlytimer_init() stops being a no-op. As a work-around I have updated r8a7779_earlytimer_init() so that shmobile_earlytimer_init() is called after r8a7779_register_twd(). Or in other words, the shmobile_earlytimer_init() setting of late_time_init overwrites that of twd_local_timer_common_register().

git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup Pull cgroup fix from Tejun Heo: "During the percpu reference counting update which was merged during v3.11-rc1, the cgroup destruction path was updated so that a cgroup in the process of dying may linger on the children list, which was necessary as the cgroup should still be included in child/descendant iteration while percpu ref is being killed. Unfortunately, I forgot to update cgroup destruction path accordingly and cgroup destruction may fail spuriously with -EBUSY due to lingering dying children even when there's no live child left - e.g. "rmdir parent/child parent" will usually fail. This can be easily fixed by iterating through the children list to verify that there's no live child left. While this is very late in the release cycle, this bug is very visible to userland and I believe the fix is relatively safe.

It's very late in the cycle but this definitely is a -stable material. The problem is that workqueue worker tasks may process unlimited number of work items back-to-back without every yielding inbetween. This usually isn't noticeable but a work item which re-queues itself waiting for someone else to do something can deadlock with stop_machine. stop_machine will ensure nothing else happens on all other cpus and the requeueing work item will reqeueue itself indefinitely without ever yielding and thus preventing the CPU from entering stop_machine. Kudos to Jamie Liu for spotting and diagnosing the problem.

2013-08-30drm: implement experimental render nodesDavid Herrmann
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: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
