RE: [PATCH v4 0/9] ARM: davinci: remoteproc support
I have uploaded the commits corresponding to this patch set to a public repo on GitHub, forked from Linus' v3.7-rc2 tag on his "linux" repo. These commits are on a branch named "davinci-remoteproc", here is the URL: https://github.com/RTivy/linux/tree/davinci-remoteproc This should make for an easier review of the changes.

Is there a sample application we could use to exercise the driver? Looks like we need some firmware to load on the DSP too.

RE: [PATCH v4 0/9] ARM: davinci: remoteproc support
Sekhar, At this point we have some examples/tests that exercise the davinci remoteproc framework using a socket layer that exists only in personal repos. Ohad created rpmsg-based socket support for the kernel using vrings, and along with SYS/BIOS-based content developed by my TI team and others, it allows a SysLink-like MessageQ implementation to be used between the DSP and Linux user apps. These apps consist of a Linux app communicating with the DSP firmware file loaded by remoteproc. They rely on the rpmsg-based socket support, so they're of no use without that. What I can do, for now, is provide a simple DSP firmware file that prints a "Hello, world" to a SYS/BIOS trace buffer that is known to remoteproc, and the remoteproc driver can be used to display the trace buffer contents through debugfs. However, this won't exercise the run-time component of davinci remoteproc (which is really just interrupt support between the DSP and ARM). I will do this and upload the firmware file and a README to my GitHub repo. I will provide just the firmware binary since the capability to build it from source relies on SYS/BIOS, TI IPC, and XDC packages/installations.
