2017-01-06drm/sti: do not post HQVDP command if no updateFabien DESSENNE1-0/+15
Do not process update requests with unmodified parameters. Since the HQVDP command queue is limited to 2, we shall take care of not posting unneeded commands, which would abusively fill the command queue leading to frame update skip. This typically happens when the driver is called with legacy (non-atomic) IOCTL : in that case atomic_update() is called multiple times with the same parameters.

2017-01-06drm/sti: allow audio playback on HDMI even if disabled.Arnaud Pouliquen1-104/+101
This fix allows to play audio while HDMI is disconnected. When HDMI is disable, audio configuration is stored and samples are dropped (by HDMI IP). When HDMI is enabled, audio HDMI configuration is applied and samples are outputted on HDMI wire. Signed-off-by: Arnaud Pouliquen <[email protected]> Acked-by: Vincent Abriou <[email protected]>

2017-01-06drm: allow to use mmuless SoCBenjamin Gaignard4-2/+101
Some SoC without MMU have display driver where a drm/kms driver could be implemented. Before doing such kind of thing drm/kms must allow to use mmuless devices. This patch propose to remove MMU configuration flag and add a cma helper function to help implementing mmuless display driver version 4: - add documentation about drm_gem_cma_get_unmapped_area() - stub it MMU case Signed-off-by: Benjamin Gaignard <[email protected]> [danvet: Use recommended struct member references in kernel-doc.] Signed-off-by: Daniel Vetter <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected]

The following commit: 8196dab4fc15 ("x86/cpu: Get rid of compute_unit_id") ... broke the initial strategy for Bulldozer-based cores' topology, where we consider each thread of a compute unit a standalone core and not a HT or SMT thread. Revert to the firmware-supplied core_id numbering and do not make them thread siblings as we don't consider them for such even if they technically are, more or less.

2017-01-06thermal: core: move tz->device.groups cleanup to thermal_releaseJacob von Chorus1-5/+5
The device_unregister call in thermal_zone_device_unregister causes the thermal_zone_device structure to be freed before the call to free the dynamically allocated attribute groups. This leads to a kernel panic. Furthermore, the 4 calls to free the trip point attribute structures occur before the call to unregister the device, leading to a kernel panic when sysfs attempts to access the attributes to remove them. Here is an example of a kernel panic when the cpu thermal zones are removed upon cpu offline: BUG: unable to handle kernel NULL pointer dereference at (null) IP: strlen+0x0/0x20 <snip> Call Trace: ? kernfs_name_hash+0x17/0x80 kernfs_find_ns+0x3f/0xd0 kernfs_remove_by_name_ns+0x36/0xa0 remove_files.isra.1+0x36/0x70 sysfs_remove_group+0x44/0x90 sysfs_remove_groups+0x2e/0x50 device_remove_attrs+0x5e/0x90 device_del+0x1ea/0x350 device_unregister+0x1a/0x60 thermal_zone_device_unregister+0x1f2/0x210 pkg_thermal_cpu_offline+0x14f/0x1a0 [x86_pkg_temp_thermal] ? kzalloc.constprop.2+0x10/0x10 [x86_pkg_temp_thermal] cpuhp_invoke_callback+0x8d/0x3f0 cpuhp_down_callbacks+0x42/0x80 cpuhp_thread_fun+0x8b/0xf0 smpboot_thread_fn+0x110/0x160 kthread+0x101/0x140 ? sort_range+0x30/0x30 ? kthread_park+0x90/0x90 ret_from_fork+0x25/0x30 This patch moves the kfree calls to clean up the dynamic attributes to the thermal_class's thermal_zone_device release function.

2017-01-05md/r5cache: assign conf->log before r5l_load_log()Song Liu1-1/+3
r5l_load_log() calls functions that requires a proper conf->log, for example, r5c_is_writeback(). Therefore, we should set conf->log before calling r5l_load_log(). If r5l_load_log() fails, conf->log is set back to NULL. Signed-off-by: Song Liu <[email protected]> Signed-off-by: Shaohua Li <[email protected]>
2017-01-05md/r5cache: simplify handling of sh->log_start in recoverySong Liu1-15/+12
We only need to update sh->log_start at the end of recovery, which is r5c_recovery_rewrite_data_only_stripes(), so it is not necessary to set it before that. In this patch, log_start is removed from r5c_recovery_alloc_stripe(). After updating all sh->log_start, rewrite_data_only_stripes() also updates log->next_checkpoints to the last sh->log_start.
