Use storage_close() to free up the shadow buffers as well, to avoid any lingering allocations. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

We're not joining the start and stop threads, so create them in detached state to avoid having their resources lingering. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

According to valgrind the modalias read from the remoteproc device is not NUL-terminated, so do this to avoid reading in the weeds. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

2020-11-21rproc: Support -s for PAS based remoteproc as wellBjorn Andersson
The old mechanism searched for remoteproc instances from the qcom_q6v5_mss driver, but in modern platforms the MSA based remoteproc model has been replaced by the PAS based one. As such we use the common qcom_q6v5_pas driver - as with other subsystems. Use the modalias to find remoteproc drivers with the mpss-pas or mss-pil compatible to find these, and fall back to the old heuristics if this fails.

2020-11-20rmtfs: Exit even though there's no rprocfdBjorn Andersson
Attempting to shut down a system with rmtfs running without an associated remoteproc results in systemd waiting forever for the remoteproc code to never signal that it's done. Instead exit immediately when signalled, when there's no associated remoteproc. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

2020-09-28storage: Use -o option to override partition by-nameAmit Pundir
Instead of hardcoding BY_PARTLABEL_PATH for AOSP, reuse -o option as suggested by Bjorn to expand John's patch to find correct partition by-name on newer kernels (which is /dev/block/platform/soc*/*.*/by-name). For example: On db845c running v5.4+ kernel we run: rmtfs -o /dev/block/platform/soc@0/1d84000.ufshc/by-name -P -r -s Signed-off-by: Amit Pundir <amit.pundir@linaro.org> Signed-off-by: John Stultz <john.stultz@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

2019-07-28storage: Track opened files without backing storageBjorn Andersson
Upon populating the shadow_buf the no fd is associated with the rmtfd. Therefor the next open request will conclude that the rmtfd is available and use the same entry. Fix this by checking for both associated fd and shadow_buf in the open call.

2019-07-17storage: Support operating on raw partitionsBjorn Andersson
Most devices has partitions named modemst1, modemst2, fsg and fsc backing the rmtfs. Add a new argument '-P' to get the storage implementation to use these partitions directly instead of files. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2019-07-17storage: Allow read only backing storageBjorn Andersson
Add a new argument '-r' to prevent writes back to the backing storage. This is useful for experimenting with the remote storage, without having the files overwritten. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2019-07-17storage: Revise APIBjorn Andersson
Pass "struct rmtfd" instead of file descriptors in the interface. This cleans up the api a little bit, but more importantly allow us to associate additional things with the remote file descriptors. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2019-07-17storage: Rename caller to "remote fd"Bjorn Andersson
The caller (and caller_id) are really "remote file descriptors", so rename them based on this. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2019-07-17rmtfs: Use pread/pwrite for storageBjorn Andersson
Instead of relying on an initial lseek, use pread/pwrite. This creates a cleaner interface towards the storage.c implementation, allowing us to provide a memory-only implementation of the backing storage. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2018-12-19storage: Allow specifying the storage directoryEvan Green
Enable the specification of storage paths other than /boot, using a new -o command line argument. Getoptify the command line arguments for better processing.
2018-12-19rmtfs: Better support for EFS backed by filesEvan Green
Currently, in order to back the EFS storage with a regular file, those files have to be pre-allocated, and with their correct size. This is especially problematic when preparing a minimal FSG, since we do not know ahead of time what size to pre-allocate. Allow reads that go beyond the end of the backing storage to simply read zeroes. When a write comes in, the file will be automatically expanded to the correct size. (And should really only be written if a full sector was pulled out of the modem). For solutions that use partitions instead of files, this change should be a no-op.

2018-07-26rmtfs: remove unused cpu_to_le32 and le32_to_cpu functionsupstream/0.0+2g0d3c49ecBen Chan
This patch addresses the following compiler warnings on unused function: rmtfs.c:24:22: warning: unused function 'cpu_to_le32' [-Wunused-function] static inline __le32 cpu_to_le32(uint32_t x) { return htole32(x); } ^ rmtfs.c:25:24: warning: unused function 'le32_to_cpu' [-Wunused-function] static inline uint32_t le32_to_cpu(__le32 x) { return le32toh(x); } ^
2018-07-05rmtfs: fix the type of the phys_address argument of rmtfs_mem_ptr()Ben Chan
The 'phys_address' argument of rmtfs_mem_read() and rmtfs_mem_write() is an 'unsigned long' type value, which is then passed to the 'phys_address' argument of rmtfs_mem_ptr(), which is an 'unsigned int' type value. This patch fixes the mismatch. Signed-off-by: Ben Chan <benchan@chromium.org>
2018-07-05sharedmem: use 'unsigned long long' for memory region parsingBrian Norris
I see warnings like this: sharedmem.c:89:44: warning: incompatible pointer types passing 'uint64_t *' (aka 'unsigned long long *') to parameter of type 'unsigned long *' [-Wincompatible-pointer-types] Since 'unsigned long' might actually be smaller than 'uint64_t', we should really upgrade to 'unsigned long long' parsing. At the same time, the existing error handling was wrong: it should have been looking for ULONG_MAX (per the man page). Convert that to ULLONG_MAX to fix that bug while we're at it.
