Hi,
"CONFIG_BRIDGE_DVFS" hasn't been verified since it requires the latest
PM patches. I will wait for the new pm-* branch.
The changes against the previous are:
Ramesh Gupta (1):
BRIDGE Power Management cleanup
Tony Lindgren (1):
DSPBRIDGE: Flush posted write when acking mailbox irq
TI's dspbridge patchset has been rebased on the latest l-o just for
its easy intergration. Most of the patches just came from o-z(Thanks
TI dspbridge team!) and I just collected them. The latest one is:
http://4869037.web.fc2.com/tidspbridge-20081107.tgz
So steps are:
$ git clone http://www.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git
$ cd linux-omap-2.6
$ wget http://4869037.web.fc2.com/tidspbridge-<date>.tgz
$ tar xvzf tidspbridge-<date>.tgz
$ git am *.patch
$ make <your omap3 board>_defconfig
$ make menuconfig # add the following options in the menuconfig
...
CONFIG_FB_OMAP_CONSISTENT_DMA_SIZE=14
...
#
# CBUS support
#
# CONFIG_CBUS is not set
CONFIG_MPU_BRIDGE=m
# CONFIG_BRIDGE_DVFS is not set
CONFIG_BRIDGE_DEBUG=y
...
You can get bridge sample binaries as below:
https://omapzoom.org/gf/download/frsrelease/132/632/dspbridge_binaries.tar.bz2
And extract it somewhere on target rootfs. After kernel booted up:
$ depmod -a
$ modprobe bridgedriver base_img=ddspbase_tiomap3430.dof64P
$ <Thy some sample applications>
If I missed something here, please let me know.
