At firmware build time, the resource table for the Xilinx zynqmp_r5 is set up with notifyid==0 for the rpmsg virtio device. The vrings are set up with notifyid==1 for vring0 and notifyid==2 for vring1. 2. When the firmware is loaded onto the R5 via the Linux remoteproc sysfs interface, the kernel remoteproc implementation ignores the notifyid values for the vrings, and reallocates them, changing the resource table. On the Xilinx configuration I tested on, this results in vring0 being allocated notifyid 0, and vring1 being allocated notifyid 1. 3. When the remote processor is started, it parses the resource table. When it gets to the virtio device, it calls handle_vdev_rsc(), which in turn calls remoteproc_allocate_id() with the vdev's notifyid of 0. This successfully returns 0. Then handle_vdev_rsc() goes through the vrings. On vring0, it calls remoteproc_allocate_id(), with notifyid set to 0, because Linux changed vring0.notifyid from 1 to 0 in (2) above. This results in remoteproc_allocate_id() returning RSC_NOTIFY_ID_ANY. This causes handle_vdev_rsc() to return -RPROC_ERR_RSC_TAB_NP after commit 03c80a1, which causes the firmware startup to fail. This appeared to work in previous versions, because remoteproc_allocate_id() returning RSC_NOTIFY_ID_ANY was effectively ignored, leaving the notifyid unchanged and allowing execution to continue.

Items for OpenAMP RP call

by ben levinsky

Hi All, I have 2 items for discussion for the community call tomorrow: For the Remoteproc-core API rproc_get_by_child I have a use case where I would like to call this on the current rproc->device. 2 things: 1. At https://github.com/torvalds/linux/blob/master/drivers/remoteproc/remoteproc… There may be a bug here in that if the device is copied, then device->type comparison will fail. Can we change this to “if (!strncmp(dev->type->name, (&rproc_type)->name, strlen((&rproc_type)->name)) ? That way even if the device is copied the check will work. 1. For the same API, is it Ok to extend the for loop so it supports search on the ‘current’ device passed in? That is change https://github.com/torvalds/linux/blob/master/drivers/remoteproc/remoteproc… “for (dev = dev->parent; dev; dev = dev->parent) {“ to “for (; dev; dev = dev->parent) {“ This way we can account for the current device having the rproc dev. The reasoning for why this arises is that I have a use case where a driver is trying to call rproc_boot() to establish an RPMsg connection. (1) comes up because a device structure is copied so the comparison will not work as currently constructed. (2) comes up in our use case because the rproc structure device in an internal driver doesn’t yet have a child to iterate up from. (2) is solved in our use case by starting at the current device.

Delaying Release of OpenAMP Library v2022.10

by Ed Mooring

Hi all, During the late stages of testing of the v2022.10 OpenAMP library, I ran across a failure that looks like there is an unexpected interaction between the library and the Linux remoteproc implementations. We have decided to delay the release until we understand the problem better. Regards, Ed M

In Some error cases the application can need to release it instead of sending it to the remote side. As the virtqueue is updated when the buffer it get, it is not possible to manage this use case at virtqueue level. This patchset implements the release based on a buffer recycler. The principle is to store the released buffer in a 'reclaimer' list. On next get pmsg_virtio_get_tx_buffer call the buffer is reused.

This was because the call to copy_from_shbuf() was now inlined by the optimizer and the compiler generated code that used 8-byte copies ("ldp x10, x11 [x4, #16]" followed by the corresponding store instruction). The bus error happened when the address in x4 (the index) was 4-byte aligned, but not 8-byte aligned. This would not be a problem with normal user-space memory, but the memory used for the shared buffer between the remote processor and Linux is mapped as device memory. On AArch64, device memory is strictly ordered and the alignment and width of accesses must match. Replace copy_from_shbuf() with a call to metal_io_block_read(), which is intended to do this sort of thing, and also makes this a better example of how to use OpenAMP. Return error only on a negative return value from copy_from_shbuf in rpmsg_endpoint_cb.
