Hi All, The following is a revised version of the series that adds the IPC-only mode support for the TI K3 R5F and DSP (C66x and C71x) remoteprocs covering AM65x, J721E, J7200 and AM64x SoCs. Patches are on top of 5.14-rc1 (the other dependent patches from v1 made it into 5.14-rc1). Please see the v1 cover-letter [1] for the design details of the 'IPC-only' mode functionality. The following are the main changes from v1, please see the individual patches for the exact deltas: - The first patch in v1 "remoteproc: Introduce rproc_detach_device() wrapper" is dropped - Removed the addition of the rproc state flag 'detach_on_shutdown' and the 'ipc-only' state flag in each of the remoteproc drivers - IPC-only mode and remoteproc mode are supported by registering only the appropriate rproc ops. The following is a summary of patches in v2: - Patch 1 enhances the remoteproc core to restrict stop on early-booted remoteprocs. - Patches 2 and 4 refactor the mailbox request code out of start in the K3 R5F and DSP remoteproc drivers for reuse in the new attach callbacks. - Patch 3 adds the IPC-only mode support for R5F. - Patch 5 adds the IPC-only mode support for both K3 C66x and C71x DSPs. I have re-verified the different combinations on J721E, J7200 and AM65x SoCs. AM64x currently lacks early-boot support, but the logic is ready for Single-CPU and Split modes that are specific to AM64x SoCs. regards Suman [1] https://patchwork.kernel.org/project/linux-remoteproc/cover/20210522000309.26134-1-s-anna@xxxxxx/ Suman Anna (5): remoteproc: Add support for detach-only during shutdown remoteproc: k3-r5: Refactor mbox request code in start remoteproc: k3-r5: Add support for IPC-only mode for all R5Fs remoteproc: k3-dsp: Refactor mbox request code in start remoteproc: k3-dsp: Add support for IPC-only mode for all K3 DSPs drivers/remoteproc/remoteproc_cdev.c | 7 + drivers/remoteproc/remoteproc_core.c | 5 +- drivers/remoteproc/remoteproc_sysfs.c | 6 + drivers/remoteproc/ti_k3_dsp_remoteproc.c | 197 ++++++++++++---- drivers/remoteproc/ti_k3_r5_remoteproc.c | 265 +++++++++++++++++++--- 5 files changed, 407 insertions(+), 73 deletions(-) -- 2.32.0
