SUMMARY = "Qualcomm RTSS Mailbox Kernel Driver Module"
Comment thread
sargarram7 marked this conversation as resolved.
DESCRIPTION = "Dynamically Loadable Kernel Module (DLKM) for RTSS mailbox communication. \
Provides mailbox IPC communication between APSS and RTSS. \
NOTICE / LIMITATIONS: this driver is still being upstreamed and its uAPI \
(rtss_mailbox_uapi.h) is not yet frozen and may change before upstream \
acceptance - see rtss-mailbox-kmd's README for details."

SUMMARY = "Qualcomm RTSS Mailbox UAPI headers"
Comment thread
sargarram7 marked this conversation as resolved.
DESCRIPTION = "IOCTL/struct definitions shared between the RTSS mailbox kernel \
driver (rtss-mailbox-kmd) and userspace (rtss-mailbox-umd). Packaged \
standalone so userspace can build against the UAPI without depending on \
the kernel module recipe. \
NOTICE / LIMITATIONS: this uAPI is not yet frozen and may change before \
upstream acceptance - see rtss-mailbox-kmd's README for details."

Why do you need the headers outside of the DLKM? Please squash both recipes.

ci check layer was failing, so referred other dlkm uapi header install logic for umd,
after making split and removing dependency of umd on kmd ci check passed.
