2020-05-12remoteproc: qcom_q6v5_mss: Drop accesses to MPSS PERPH register spaceSibi Sankar1-84/+18
7C retail devices using MSA based boot will result in a fuse combination which will prevent accesses to MSS PERPH register space where the mpss clocks and halt-nav reside. So drop all accesses to the MPSS PERPH register space. Issuing HALT NAV request and turning on the mss clocks as part of SSR will no longer be required since the modem firmware will have the necessary fixes to ensure that there are no pending NAV DMA transactions.

2020-04-20remoteproc: Use a local copy for the name fieldSuman Anna1-1/+5
The current name field used in the remoteproc structure is simply a pointer to a name field supplied during the rproc_alloc() call. The pointer passed in by remoteproc drivers during registration is typically a dev_name pointer, but it is possible that the pointer will no longer remain valid if the devices themselves were created at runtime like in the case of of_platform_populate(), and were deleted upon any failures within the respective remoteproc driver probe function. So, allocate and maintain a local copy for this name field to keep it agnostic of the logic used in the remoteproc drivers.

Current implementation of the sysmon driver does not support adding notifications for other remoteproc events - prepare, start, unprepare. Clients on the remoteproc side might be interested in knowing when a remoteproc boots up. This change adds the ability to send the notification type along with the name. For example, audio DSP is interested in knowing when modem has crashed so that it can perform cleanup and wait for modem to boot up before it starts processing data again.

2020-04-19remoteproc: Fix IDR initialisation in rproc_alloc()Alex Elder1-2/+1
If ida_simple_get() returns an error when called in rproc_alloc(), put_device() is called to clean things up. By this time the rproc device type has been assigned, with rproc_type_release() as the release function. The first thing rproc_type_release() does is call: idr_destroy(&rproc->notifyids); But at the time the ida_simple_get() call is made, the notifyids field in the remoteproc structure has not been initialized. I'm not actually sure this case causes an observable problem, but it's incorrect. Fix this by initializing the notifyids field before calling ida_simple_get() in rproc_alloc().

There are many places where all basic VMA access flags (read, write, exec) are initialized or checked against as a group. One such example is during page fault. Existing vma_is_accessible() wrapper already creates the notion of VMA accessibility as a group access permissions. Hence lets just create VM_ACCESS_FLAGS (VM_READ|VM_WRITE|VM_EXEC) which will not only reduce code duplication but also extend the VMA accessibility concept in general.
