2021-10-20drm/i915: mark up internal objects with start_cpu_writeMatthew Auld
While the pages can't be swapped out, they can be discarded by the shrinker. Normally such objects are marked with __I915_MADV_PURGED, which can't be unset, and therefore requires a new object. For kernel internal objects this is not true, since the madv hint is reset for our special volatile objects, such that we can re-acquire new pages, if so desired, without needing a new object. As a result we should probably be paranoid here and put the object back into the CPU domain when discarding the pages, and also correctly set cache_dirty, if required.

On non-LLC platforms, force the flush-on-acquire if this is ever swapped-in. Our async flush path is not trust worthy enough yet(and happens in the wrong order), and with some tricks it's conceivable for userspace to change the cache-level to I915_CACHE_NONE after the pages are swapped-in, and since execbuf binds the object before doing the async flush, there is a potential race window.

2021-10-20media: allegro: add encoder buffer supportMichael Tretter
The encoder buffer serves as a cache for reference frames during the encoding process. The encoder buffer significantly reduces the bandwidth requirement for read accesses on the AXI ports of the VCU, but slightly reduces the quality of the encoded video. The encoder buffer must be configured as a whole during the firmware initialization and later explicitly enabled for every channel that shall use the encoder buffer. Prior to firmware version 2019.2, it was necessary to explicitly set the size of the encoder buffer for every channel. Since 2019.2 it is sufficient to enable the encoder buffer and leave the rest to the firmware. Therefore, only support the encoder buffer for firmware 2019.2 and later.

2021-10-20media: allegro: add pm_runtime supportMichael Tretter
The allegro driver must ensure that the mcu and core clocks are enabled and set to the expected clock rate before trying to load the firmware and to reset the MCU. Up until now, the driver assumed that the clocks are always enabled in the PL (programming logic), because the xlnx_vcu driver did not export the clocks to other drivers. This has changed and by explicitly enabling the clocks in the driver, this assumption can be dropped. It might even be possible to disable the clocks for the encoder if the encoder is not used. However, the behavior is not documented and it might be necessary to reinitialize the encoder after deactivating the clocks. Play it safe by sticking to the current behavior.

The VCU provides information about its configuration in a dedicated register space. These settings include, for example, the expected clock rates and the configuration of the encoder buffer. In the device tree, the settings are described by the "xlnx,vcu-settings" compatible. The settings are needed to correctly configure the clocks and the encoder buffer. Lookup the VCU settings in the device tree and make it accessible to the driver via a regmap.

2021-10-20media: allegro: fix module removal if initialization failedMichael Tretter
If the module probe finished, but the firmware initialization failed, removing the module must not revert the firmware initialization. Add a field to track the status of the firmware initialization and only roll it back, if the firmware was successfully initialized.

2021-10-20media: allegro: ignore interrupt if mailbox is not initializedMichael Tretter
The mailbox is initialized after the interrupt handler is installed. As the firmware is loaded and started even later, it should not happen that the interrupt occurs without the mailbox being initialized. As the Linux Driver Verification project (linuxtesting.org) keeps reporting this as an error, add a check to ignore interrupts before the mailbox is initialized to fix this potential null pointer dereference.

2021-10-20bcache: use bvec_kmap_local in bch_data_verifyChristoph Hellwig
Using local kmaps slightly reduces the chances to stray writes, and the bvec interface cleans up the code a little bit. Also switch from page_address to bvec_kmap_local for cbv to be on the safe side and to avoid pointlessly poking into bvec internals.
