Thanks Peng. > > From: Peng Fan <peng.fan@xxxxxxx> > > V4: > Based on Bjorn's comments on V2-2 > Move the rproc_has_feature/rproc_set_feature to remoteproc_internal.h > and Keep rproc_features still in remoteproc.h, because we use > RPROC_MAX_FEATURES to declare bitmap. > Update commit log for patch 2/2, and add comments > > V3: > Resend the wrong labeled patchset > https://patchwork.kernel.org/project/linux-remoteproc/list/?series=621311 > > Write a cover-letter > To i.MX8QM/QXP, they have a M4 core self-recovery capability without > Linux loading firmware. The self recovery is done by SCU(System Control > Unit). Current remoteproc framework only support Linux help recovery > remote processor(stop, loading firmware, start). This patchset is support > remote processor self recovery(attach recovery). > > In order to avoid introducing a new variable(bool support_self_recovery), > patch 1 introduce a new function, rproc_has_feature to make code easy to > extend, cleaner, such as we could move "bool has_iommu" to > rproc_has_feature(rproc, RPROC_FEAT_IOMMU). > > Patch 2 is introduce a new function rproc_attach_recovery for self recovery, > the original logic move to rproc_firmware_recovery meaning needs linux to > help recovery. > > V2-version 2: > https://patchwork.kernel.org/project/linux-remoteproc/list/?series=621311 > Introduce rproc_has_feature > > V2-version 1: > > https://patchwork.kernel.org/project/linux-remoteproc/patch/20220126085 > 120.3397450-1-peng.fan@xxxxxxxxxxx/ > Nothing change in V2. > Only move this patch out from > https://patchwork.kernel.org/project/linux-remoteproc/list/?series=604364 > > > > Peng Fan (2): > remoteproc: introduce rproc features > remoteproc: support attach recovery after rproc crash > > drivers/remoteproc/remoteproc_core.c | 67 > +++++++++++++++++------- > drivers/remoteproc/remoteproc_internal.h | 10 ++++ > include/linux/remoteproc.h | 7 +++ > 3 files changed, 65 insertions(+), 19 deletions(-) > > -- > 2.25.1
