2020-07-07drm/i915/gt: Pin the rings before marking activeChris Wilson
On eviction, we acquire the vm->mutex and then wait on the vma->active. Therefore when binding and pinning the vma, we must follow the same sequence, lock/pin the vma then mark it active. Otherwise, we mark the vma as active, then wait for the vm->mutex, and meanwhile the evictor holding the mutex waits upon us to complete our activity.

2020-07-07ionic: centralize queue reset codeShannon Nelson
The queue reset pattern is used in a couple different places, only slightly different from each other, and could cause issues if one gets changed and the other didn't. This puts them together so that only one version is needed, yet each can have slighty different effects by passing in a pointer to a work function to do whatever configuration twiddling is needed in the middle of the reset. This specifically addresses issues seen where under loops of changing ring size or queue count parameters we could occasionally bump into the netdev watchdog. v2: added more commit message commentary Fixes: 4d03e00a2140 ("ionic: Add initial ethtool support") Signed-off-by: Shannon Nelson <snelson@pensando.io> Acked-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2020-07-07net: qed: fix buffer overflow on ethtool -dAlexander Lobakin
When generating debug dump, driver firstly collects all data in binary form, and then performs per-feature formatting to human-readable if it is supported. For ethtool -d, this is roughly incorrect for two reasons. First of all, drivers should always provide only original raw dumps to Ethtool without any changes. The second, and more critical, is that Ethtool's output buffer size is strictly determined by ethtool_ops::get_regs_len(), and all data *must* fit in it. The current version of driver always returns the size of raw data, but the size of the formatted buffer exceeds it in most cases. This leads to out-of-bound writes and memory corruption. Address both issues by adding an option to return original, non-formatted debug data, and using it for Ethtool case. v2: - Expand commit message to make it more clear; - No functional changes.

2020-07-07net: ethernet: fec: prevent tx starvation under high rx loadTobias Waldekranz
In the ISR, we poll the event register for the queues in need of service and then enter polled mode. After this point, the event register will never be read again until we exit polled mode. In a scenario where a UDP flow is routed back out through the same interface, i.e. "router-on-a-stick" we'll typically only see an rx queue event initially. Once we start to process the incoming flow we'll be locked polled mode, but we'll never clean the tx rings since that event is never caught. Eventually the netdev watchdog will trip, causing all buffers to be dropped and then the process starts over again. Rework the NAPI poll to keep trying to consome the entire budget as long as new events are coming in, making sure to service all rx/tx queues, in priority order, on each pass.

2020-07-07dm: do not use waitqueue for request-based DMMing Lei
Given request-based DM now uses blk-mq's blk_mq_queue_inflight() to determine if outstanding IO has completed (and DM has no control over the blk-mq state machine used to track outstanding IO) it is unsafe to wakeup waiter (dm_wait_for_completion) before blk-mq has cleared a request's state bits (e.g. MQ_RQ_IN_FLIGHT or MQ_RQ_COMPLETE). As such dm_wait_for_completion() could be left to wait indefinitely if no other requests complete.

This patch fixes a bug which does not let FAN mode to be changed from sysfs(pwm1_enable). i.e pwm1_enable can not be set to 3, it will always remain at 0. This is caused because the device driver handles the result of "read_u8_from_i2c(client, REG_FAN_CONF1, &conf_reg)" incorrectly. The driver thinks an error has occurred if the (result != 0).

2020-07-07drm/ast: Keep cursor HW BOs mappedThomas Zimmermann
Updating the image in a cursor's HW BO requires a mapping of the BO's buffer in the kernel's address space. Cursor image updates can happen frequently and create CPU overhead. As cursor HW BOs are small and never move, they are now map exactly once during the initialization and the mapping is used throughout the driver's lifetime. This change also removes a possible source of failures from ast_cursor_show(). As the helper does not establish mappings, it cannot fail.

2020-07-07drm/vc4: txp: Turn the TXP into a CRTC of its ownMaxime Ripard
The TXP so far has been leveraging the PixelValve infrastructure in the driver, that was really two things: the interaction with DRM's CRTC concept, the setup of the underlying pixelvalve and the setup of the shared HVS, the pixelvalve part being irrelevant to the TXP since it accesses the HVS directly. Now that we have a clear separation between the three parts, we can represent the TXP as a CRTC of its own, leveraging the common CRTC and HVS code, but leaving aside the pixelvalve setup.

2020-07-07drm/vc4: crtc: Only access the PixelValve registers if we have toMaxime Ripard
The CRTC hooks are called both for the TXP and the pixelvalve, yet some will read / write the registers as if the device was a pixelvalve, which won't really work. Let's make sure we only access those registers if we are running on a PixelValve.

2020-07-07drm/vc4: crtc: Split CRTC data in twoMaxime Ripard
The vc4_crtc_data structure is currently storing data related to both the general CRTC information needed by the rest of the vc4 driver (like HVS output and available FIFOs) and some related to the pixelvalve attached to that CRTC. Let's split this into two structures so that we can reuse the CRTC part into the TXP later on.

2020-07-07drm/vc4: crtc: Move HVS setup code to the HVS driverMaxime Ripard
The CRTC in vc4 is backed by two devices, the HVS that does the composition and the PixelValve that does the timing generation. The writeback is kind of a special case since it doesn't have an associated pixelvalve but goes straight from the HVS to the TXP. Therefore, it makes sense to move out the HVS setup code into helpers so that we can also reuse them from the TXP driver.
