| * virtio: allow drivers to request IRQ affinity when creating VQsChristoph Hellwig2017-02-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a struct irq_affinity pointer to the find_vqs methods, which if set is used to tell the PCI layer to create the MSI-X vectors for our I/O virtqueues with the proper affinity from the start. Compared to after the fact affinity hints this gives us an instantly working setup and allows to allocate the irq descritors node-local and avoid interconnect traffic. Last but not least this will allow blk-mq queues are created based on the interrupt affinity for storage drivers.

* | remoteproc: qcom: mdt_loader: Use signed type for offsetBjorn Andersson2017-02-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the transition from using rproc_da_to_va(), the type of the load offset became unsigned. This causes the subsequent check to let negative values less than p_memsz + mem_size through and we write outside of the buffer. Change the type back to a signed value to catch this.

| | | | | | | | | | | | | | | | | | | | | | | | The rproc_add_virtio_devices() requests firmware asynchronously and triggers boot if the auto_boot flag is set. However, this asynchronous call seems to be redundant for non auto-boot scenario since the rproc_boot() would call request_firmware() anyways.

* | remoteproc: Drop firmware_loading_completeSarangdhar Joshi2017-01-301-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | firmware_loading_complete is used to synchronize operations on rproc while asynchronous firmware loading is in progress. However, rproc_boot() no longer waits on firmware_loading_complete. Hence drop this completion variable altogether and handle the race between rproc_del() and rproc_boot() using new state RPROC_DELETED. The request_firmware_nowait() will hold the reference to rproc device by using a get_device()/put_device(), so the rproc struct will remain valid even when we return from rproc_del() before the asynchronous call to rproc_fw_config_virtio() completes.

It introduces a regression when following sequence is executed: rproc_boot --> rproc_shutdown --> rproc_boot Second rproc_boot call crashes on register_virtio_device as device is already existing. Issue is previous vdev is never released when rproc is stop because associated refcount is too high. kref_get introduces is not needed as kref_init already initializes krefcount to 1 because it considers associated variable as used. This introduces a misalignment between kref_get and kref_put calls.

* remoteproc: Add support for xo clockSarangdhar Joshi2016-11-171-1/+29
| | | | | | | | | | Add xo clock support required to boot up Qualcomm ADSP processor. The ADSP remoteproc driver keeps xo clock enabled until the driver receives "handover" irq, in order to allow ADSP processor to vote for xo clock with rpm.

| | | | | | | | | | | | | | The newly added driver tries to 'select' a symbol that it has an implicit dependency on, which confuses Kconfig: subsection "Kconfig recursive dependency limitations" drivers/remoteproc/Kconfig:3: symbol REMOTEPROC is selected by QCOM_ADSP_PIL As REMOTEPROC is itself user-visible, we clearly should not select it from a driver, removing the line fixes the problem.

| * remoteproc: Update Kconfig setup to 'depends on REMOTEPROC'Peter Griffin2016-10-181-8/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make REMOTEPROC core a selectable kconfig option, and update remoteproc client drivers to 'depends on' the core. This avoids some nasty Kconfig recursive dependency issues. Also when using menuconfig client drivers will be hidden until the core has been enabled. Documentation/kbuild/kconfig-language.txt: Note: select should be used with care. select will force a symbol to a value without visiting the dependencies. By abusing select you are able to select a symbol FOO even if FOO depends on BAR that is not set. In general use select only for non-visible symbols (no prompts anywhere) and for symbols with no dependencies. That will limit the usefulness but on the other hand avoid the illegal configurations all over.

| * remoteproc: st_slim_rproc: add a slimcore rproc driverPeter Griffin2016-10-183-2/+370
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | slim core is used as a basis for many IPs in the STi chipsets such as fdma and demux. To avoid duplicating the elf loading code in each device driver a slim rproc driver has been created. This driver is designed to be used by other device drivers such as fdma, or demux whose IP is based around a slim core. The device driver can call slim_rproc_alloc() to allocate a slim rproc and slim_rproc_put() when finished. This driver takes care of ioremapping the slim registers (dmem, imem, slimcore, peripherals), whose offsets and sizes can change between IP's. It also obtains and enables any clocks used by the device. This approach avoids having a double mapping of the registers as slim_rproc does not register its own platform device. It also maps well to device tree abstraction as it allows us to have one dt node for the whole device. All of the generic rproc elf loading code can be reused, and we provide start() stop() hooks to start and stop the slim core once the firmware has been loaded. This has been tested successfully with fdma driver. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Signed-off-by: Vinod Koul <vinod.koul@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tie between the main WCNSS driver and the IRIS driver causes a circular dependency between the two modules. Neither part makes sense to have on their own so lets merge them into one module. For the sake of picking up the clock and regulator resources described in the iris of_node we need an associated struct device. But, to keep the size of the patch down we continue to represent the IRIS part as its own platform_driver, within the same module, rather than setting up a dummy device.

* | remoteproc: Merge table_ptr and cached_table pointersBjorn Andersson2016-11-151-16/+10
| | | | | | | | | | | | | | | | | | | | | | | | As all vdev resources are allocated before we boot the remote processor we no longer need to support modifying the resource table while the remote is running. This saves us from the table_ptr dance, but more importantly allow the remote processor to enable security lock down of the loaded table memory region.
