Unsigned PD can be enabled using userspace API: https://git.codelinaro.org/linaro/qcomlt/fastrpc/-/blob/master/src/fastrpc_apps_user.c?ref_type=heads#L1173 Changes in v2: - Added separate patch to add newlines in dev_err. - Added a bug fix in fastrpc capability function. - Added a new patch to save and restore interrupted context. - Fixed config dependency for PDR support. Changes in v3: - Dropped interrupted context patch. - Splitted few of the bug fix patches. - Added Fixes tag wherever applicable. - Updated proper commit message for few of the patches. Changes in v4: - Dropped untrusted process and system unsigned PD patches. - Updated proper commit message for few of the patches. - Splitted patches in more meaningful way. - Added helped functions for fastrpc_req_mmap.
