2022-10-05remoteproc: virtio: Fix warning on bindings by removing the of_match_tableArnaud Pouliquen1-7/+1
The checkpatch tool complains that "virtio,rproc" is not documented. But it is not possible to probe the device "rproc-virtio" by declaring it in the device tree. So documenting it in the bindings does not make sense. This commit solves the checkpatch warning by suppressing the useless of_match_table.

2022-09-28remoteproc: Support attach recovery after rproc crashPeng Fan1-19/+43
Current logic only support main processor to stop/start the remote processor after crash. However to SoC, such as i.MX8QM/QXP, the remote processor could do attach recovery after crash and trigger watchdog to reboot itself. It does not need main processor to load image, or stop/start remote processor. Introduce two functions: rproc_attach_recovery, rproc_boot_recovery for the two cases. Boot recovery is as before, let main processor to help recovery, while attach recovery is to recover itself without help. To attach recovery, we only do detach and attach.

2022-09-21remoteproc: virtio: Create platform device for the remoteproc_virtioArnaud Pouliquen3-77/+80
Define a platform driver to manage the remoteproc virtio device as a platform devices. The platform device allows to pass rproc_vdev_data platform data to specify properties that are stored in the rproc_vdev structure. Such approach will allow to preserve legacy remoteproc virtio device creation but also to probe the device using device tree mechanism. remoteproc_virtio.c update: - Add rproc_virtio_driver platform driver. The probe ops replaces the rproc_rvdev_add_device function. - All reference to the rvdev->dev has been updated to rvdev-pdev->dev. - rproc_rvdev_release is removed as associated to the rvdev device. - The use of rvdev->kref counter is replaced by get/put_device on the remoteproc virtio platform device. - The vdev device no longer increments rproc device counter. increment/decrement is done in rproc_virtio_probe/rproc_virtio_remove function in charge of the vrings allocation/free. remoteproc_core.c update: Migrate from the rvdev device to the rvdev platform device. From this patch, when a vdev resource is found in the resource table the remoteproc core register a platform device.

2022-08-11virtio: find_vqs() add arg sizesXuan Zhuo1-0/+1
find_vqs() adds a new parameter sizes to specify the size of each vq vring. NULL as sizes means that all queues in find_vqs() use the maximum size. A value in the array is 0, which means that the corresponding queue uses the maximum size. In the split scenario, the meaning of size is the largest size, because it may be limited by memory, the virtio core will try a smaller size. And the size is power of 2.

When a new remoteproc boots up, send the sysmon state notification of only running remoteprocs. Sending state of remoteprocs booting up in parallel can cause a race between SSR clients of the remoteproc that is booting up and the sysmon notification for the same remoteproc, resulting in an inconsistency between which state the remoteproc that is booting up in parallel. For example - if remoteproc A and B crash one after the other, after remoteproc A boots up, if the remoteproc A tries to get the state of remoteproc B before the sysmon subdevice for B is invoked but after the ssr subdevice of B has been invoked, clients on remoteproc A might get confused when the sysmon notification indicates a different state.

2022-07-18remoteproc: qcom_q6v5_mss: map/unmap metadata region before/after useSibi Sankar1-6/+32
The application processor accessing the dynamically assigned metadata region after assigning it to the remote Q6 would lead to an XPU violation. Fix this by un-mapping the metadata region post firmware header copy. The metadata region is freed only after the modem Q6 is done with fw header authentication.

2022-07-04remoteproc: mediatek: Enable cache for mt8186 SCPAllen-KH Cheng1-1/+9
This patch is for enabling cache in SCP. There is not enough space on the SRAM of SCP. We need to run programs in DRAM. The DRAM power and latency is much larger than SRAM, so cache is used to mitigate the negative effects for performance. We set SCP registers for cache size before loading SCP FW. (8KB+8KB) and also adjust ipi_buf_offset in SRAM from 0x7bdb0 to 0x3bdb0 for enabling cache.

There is no mutex protection of these state checking for 'stop' and 'detach' which can't guarantee there is no another instance is trying to do same operation. Consider two instances case: Instance1: echo stop > /sys/class/remoteproc/remoteproc0/state Instance2: echo stop > /sys/class/remoteproc/remoteproc0/state The issue is that the instance2 case may success, Or it may fail with -EINVAL, which is uncertain. So move this state checking in rproc_cdev_write() and state_store() for 'stop', 'detach' operation to 'rproc_shutdown' , 'rproc_detach' function under the mutex protection.
