- dce-os-worker.c/.h module exposes functionality which allows
DCE KMD clients to wait/signal events.
- The current abstraction of this module has following drawbacks
which this change attempts to address:
* Name: dce-os-worker is a misnomer
- Rename to dce-wait-cond.c/.h and make it a dce-kmd core file.
- Rename functions accordingly.
* dce-os-worker module initializes data structures from tegra_dce
which makes it ineligible for re-use.
- dce-client-ipc can re-use this module as it uses exact
same functionality.
- But this module is tied with DCE-KMD core such that it has
functions that operate on fixed known inputs.
- dce_os_work_cond_sw_resource_init/deinit()
Inits/Deinits most but not all condition var resources
from tegra_dce. Eg. dce-client-ipc resources
are not initialized.
- Move this function to new core file:dce-waiters.c
- All other functions require msg_id as input and can only
operate on DCE_WAIT* resources making it ineligible
to be used by other clients like dce-client-ipc.
- Refactor these fucntions to operate on
individual wait conditions so that all DCE-KMD
core modules can reuse them.
- Additionally, this change will also remove unused functions
and macros from dce-os-cond.c/.h
- dce-client-ipc will also switch to use dce-wait-cond interface
for client ipc waits.
- Make dce-os-cond.h a common file and move OS specific impl
to dce-os-cond-internal.h
