2018-12-20media: cx23885: only reset DMA on problematic CPUsmedia/v4.20-6Brad Love2-2/+55
It is reported that commit 95f408bbc4e4 ("media: cx23885: Ryzen DMA related RiSC engine stall fixes") caused regresssions with other CPUs. Ensure that the quirk will be applied only for the CPUs that are known to cause problems. A module option is added for explicit control of the behaviour.

Adding an extra MI_STORE_DWORD_IMM to the gpu relocation path for gen3 was good, but still not good enough. To survive 24+ hours under test we needed to perform not one, not two but three extra store-dw. Doing so for each GPU relocation was a little unsightly and since we need to worry about userspace hitting the same issues, we should apply the dummy store-dw into the EMIT_FLUSH.

2018-12-12drm/i915: Allocate a common scratch pageChris Wilson7-87/+75
Currently we allocate a scratch page for each engine, but since we only ever write into it for post-sync operations, it is not exposed to userspace nor do we care for coherency. As we then do not care about its contents, we can use one page for all, reducing our allocations and avoid complications by not assuming per-engine isolation. For later use, it simplifies engine initialisation (by removing the allocation that required struct_mutex!) and means that we can always rely on there being a scratch page. v2: Check that we allocated a large enough scratch for I830 w/a Fixes: 06e562e7f515 ("drm/i915/ringbuffer: Delay after EMIT_INVALIDATE for gen4/gen5") # v4.18.20 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=108850 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181204141522.13640-1-chris@chris-wilson.co.uk Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: <stable@vger.kernel.org> # v4.18.20+ (cherry picked from commit 5179749925933575a67f9d8f16d0cc204f98a29f) [Joonas: Use new function in gen9_init_indirectctx_bb too] Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
2018-12-12drm/i915/execlists: Apply a full mb before execution for BraswellChris Wilson1-1/+6
Braswell is really picky about having our writes posted to memory before we execute or else the GPU may see stale values. A wmb() is insufficient as it only ensures the writes are visible to other cores, we need a full mb() to ensure the writes are in memory and visible to the GPU. The most frequent failure in flushing before execution is that we see stale PTE values and execute the wrong pages.

2018-12-11dm thin: send event about thin-pool state change _after_ making itMike Snitzer1-33/+35
Sending a DM event before a thin-pool state change is about to happen is a bug. It wasn't realized until it became clear that userspace response to the event raced with the actual state change that the event was meant to notify about. Fix this by first updating internal thin-pool state to reflect what the DM event is being issued about. This fixes a long-standing racey/buggy userspace device-mapper-test-suite 'resize_io' test that would get an event but not find the state it was looking for -- so it would just go on to hang because no other events caused the test to reevaluate the thin-pool's state.

2018-12-11Revert "drm/rockchip: Allow driver to be shutdown on reboot/kexec"Brian Norris1-6/+0
This reverts commit 7f3ef5dedb146e3d5063b6845781ad1bb59b92b5. It causes new warnings [1] on shutdown when running the Google Kevin or Scarlet (RK3399) boards under Chrome OS. Presumably our usage of DRM is different than what Marc and Heiko test. We're looking at a different approach (e.g., [2]) to replace this, but IMO the revert should be taken first, as it already propagated to -stable.

Without this patch the thermal driver is broken on hi3660. The dual sensors support patchset was partially merged, unfortunately the dual thermal zones definition is not available in the DT yet, so when the driver tries to register all the sensors that fails. By reducing to 1 the number of sensors on the hi3660, we switch back to the previous functionnality.

Without this patch, the thermal driver on hi6220 and hi3660 is broken. That is due because part of the posted patchset was merged but a small change in the DT was dropped. The hi6220 and hi3660 do not have an interrupt name in the DT, so finding interrupt by name fails. Fix this by returning back to the platform_get_irq() function call.

2018-12-10backlight: pwm_bl: Fix brightness levels for non-DT case.Enric Balletbo i Serra1-6/+35
Commit '88ba95bedb79 ("backlight: pwm_bl: Compute brightness of LED linearly to human eye")' allows the possibility to compute a default brightness table when there isn't the brightness-levels property in the DT. Unfortunately the changes made broke the pwm backlight for the non-DT boards. Usually, the non-DT boards don't pass the brightness levels via platform data, instead, it sets the max_brightness in their platform data and the driver calculates the level without a table. The offending patch assumed that when there is no brightness levels table we should create one, but this is clearly wrong for the non-DT case. After this patch the code handles the DT and the non-DT case taking in consideration also if max_brightness is set or not.

2018-12-09bnxt_en: Fix _bnxt_get_max_rings() for 57500 chips.Michael Chan1-4/+12
The CP rings are accounted differently on the new 57500 chips. There must be enough CP rings for the sum of RX and TX rings on the new chips. The current logic may be over-estimating the RX and TX rings. The output parameter max_cp should be the maximum NQs capped by MSIX vectors available for networking in the context of 57500 chips. The existing code which uses CMPL rings capped by the MSIX vectors works most of the time but is not always correct. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.
