SYSLINK: ipu-pm ported changes specific for 2.6.38 vanilla l-o kernel.

2011-04-07T07:43:54+00:00

This patch adds vanilla l-o 2.6.38 specific changes. The patch might get redundant once the OMAP_PM specific changes/ baseport changes go in. Check the return value of kfifo_out ti avoid a warning Do not use any constraint req/rel since the fwk is not ready yet.

syslink: ipu_pm: hack to sofreset iss & fdif After an iommufault iss and fdif need to be reset for the proper reuse of both. The proper api to call is _softreset() but for that sysc struct in hwmod needs to be enabled but that part is not ready. This is hack until the proper fix is done in sysc and the proper api can be used to softreset.

SYSLINK: Use unlocked_ioctl instead of ioctl

2011-04-07T07:43:50+00:00

This patch uses unlocked_ioctl instead of ioctl in all SysLink drivers. The support for ioctl was removed since BKL is not to be used anymore. Signed-off-by: Subramaniam C.A

SYSLINK: Migrate build changes for adding iommu-debug and enable hibernation

2011-04-07T07:43:48+00:00

syslink: ipu_pm: fix ret in idle path after recovery

2011-04-07T07:43:47+00:00

After recovery the mechanism to release all the resources and constraints was not taking in to consideration the IPU that is created behind the scenes to handle the sys and app constraints and as a consequence all the constraints attached to it were not released leading to not hit retention in idle path. That IPU behind scenes is a special rcb slot that only has constraints; the fix is taking care of this case and releases only the constraints. If the IPU is explicitly requested then it will be consider as a normal resource.

omap:iodmm-make dma call for flushing configurable

2011-04-07T07:43:39+00:00

Use dma calls for cache flushing under a configurable flag. Use this option until Multimedia integration issues are sorted out. Signed-off-by: Hari Kanigeri

syslink: ipu_pm: fix wdt and add resource cleanup

2011-04-07T07:43:24+00:00

wdt notification event was not being sent to the deh because if there are resources in use by IPU the assumption was that it is in a good state (not hanging) and the timer was being reloaded without catching the issue. This fix is avoiding that scenario adding an event PM_ALIVE, sent by ipu, that indicates there are resources in use but ipu wont hibernate, and the timer needs to be reloaded in kernel for hib_time seconds again. Also resources clean up is now done when the wd issue is catched. Change-Id: I34304763ce50ac51595a9a6b7c9305d95174f8f8 Signed-off-by: Miguel Vadillo Signed-off-by: Juan Gutierrez

syslink:ipu_pm: Modifications for timer setup for WDT

2011-04-07T07:43:23+00:00

Modified to configure timer 3 that is used to trigger hibernation and it is also used as watch dog timer. Since both ducati cores can go to retention together and if one core is not responding both need to be reset, we only use 1 timer [Hari K] The free irq while freeing checks the dev_id as the token with the dev_id that it was registered earlier. To avoid the race condition as when the remote proc frees the dmtimer handle save the handle in ipu_pm to use it as a token when passing to free_irq A cleaner solution should be investigated for watchdog timer Change-Id: I15d3c0182d84861819cc36abf1f78cbc1674375f Signed-off-by: Shahid Akhtar

SYSLINK: ipc - ipc recovery related patches

2011-04-07T07:43:13+00:00

SYSLINK: ipc - move check for in recovery state per ipc submodule With this approach, now each submodule can allow which ioctl can go through when the IPC is in recovery state. It is done by exporting a new function in ipc.

This also includes the changes to export ipc_recovery_schedule function. This function should be called by error handlers such as sys error and watchdog error.
