* usb: ehci: make HC see up-to-date qh/qtd descriptor ASAPMing Lei2012-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the helper of ehci_sync_mem to flush qtd/qh into memory immediately on some ARM, so that HC can see the up-to-date qtd/qh descriptor asap. This patch fixs one performance bug on ARM Cortex A9 dual core platform, which has been reported on quite a few ARM machines (OMAP4, Tegra 2, snowball...), see details from link of https://bugs.launchpad.net/bugs/709245. The patch has been tested ok on OMAP4 panda A1 board, and the performance of 'dd' over usb mass storage can be increased from 4~5MB/sec to 14~16MB/sec after applying this patch. SRU Justification: Impact: - without the patch, 'dd' over usb mass storage is about 4~5MB/sec. Fix: - After applying the patch, 'dd' over usb mass storage is about 14~16MB/sec.

* syslink: notify: process both cores ipc stack for each mailbox interruptSubin K G2012-08-17
| | | | | | | | | | | | | For each mailbox interrupt,process both cores(sysm3 and appm3) ipc stack. This is to fix the issue of message being dropped, when both cores tries to put the message at the same time. For example both sysm3 and appm3 are trying to write into MBX and appm3 sees that there is already a message pending by SYSM3.In this case appm3 will not interrupt A9.But A9 will only process sysm3 ipc stack.So to take care of this,process both cores ipc stack for each MBX interrupt.

* syslink: ipu_pm: fix ret in idle path after recoveryMiguel Vadillo2012-08-17
| | | | | | | | | | | | | | | | | | | 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.

* syslink: ipu_pm: fix wdt and add resource cleanupMiguel Vadillo2012-08-17
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | 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 <sakhtar@ti.com>

| | | | | | | | | | | | | | If the IPU subsystem has hibernated, there is no need to wake it up and forward suspend notifications.

Signed-off-by: Miguel Vadillo <vadillo@ti.com> syslink:ipu_pm: allow IPU hibernation -IPU self hibernation- After 5 seconds of inactivity ipu will send a notification to MPU indicating it can be turned off, mpu can proceed to turn off IPU just if there is no message (notify_send_event) going to IPU, in that case hibernation will be aborted. IPU is prepared to abort hibernation when a message arrives to its mbox. When mpu is hibernating IPU the iommu and mbox context will be saved and then rproc_sleep will be called to disable each core and also the associated gptimer, that is needed to allow retention. Whenever a message is sent to IPU the ipu_pm_restore will check and wake up IPU, if needed, restoring the iommu and mbox context and calling rproc_wake that will enable IPU and the associated gptimer again. -MPU hibernating IPU- Whenever the system suspend is sent to ipu_drv the suspend_drv will send a SUSPEND notification to IPU, it will send back an ack to MPU and then start the hibernation proccess by it self following the same scheme mentioned above but without waiting the 5 seconds, once ipu_drv receives the suspend ack it will call ipu_pm_save_ctx() in order to wait for IPU to be hibernated and in really idle then turn IPU off. This will work even if self hibernation in IPU is disable.

Signed-off-by: Miguel Vadillo <vadillo@ti.com> syslink: ipu_pm: add a core latency constraint when the ipu is running. Due to the enabling of C4 and C5 states IPU was being put in reset without allowing it to properly save the context leading to an invalid resume operation and an MMU fault by IPU side. Putting a latency constraint on IPU_CORE whenever IPU is up and running is avoiding this scenario. The constraint is released once the IPU has properly saved the context and requested again when resuming to avoid letting the ipu_core going to retention.

The notification mechanism for sending events to the host processor has been consolidated in a new module named Device Error Handler on the remote processor. The notification mechanism relies on a NotifyShm event to know about error events on the remote cores. The support has been built into the existing Devh module which registers a call back for the previously agreed event id to be used for error events. Upon receving an error event, the module will notify other kernel modules which have registered with it. It will also notify userspace applicatios through an agreed fd event. This support will be built in a following patch. For now, the module uses event id 4 to receive notify messages from remote processor. Enhacements that will follow include using a reserved event for sending notify messages. Initialize the Device Error Handler functionality in Devh. Devh registers a callback for NotifyShm event to be triggered when an error occurs on the remote core. Devh module has the support for receiving notifications from remote cores about irrecoverble errors. Userspace processes need to be notified for such events as well in order to do cleanup and recovery. Besides, such notifications can also be used to output valuable debug information about error scenarios.

Signed-off-by: Juan Gutierrez <jgutierrez@ti.com> SYSLINK: notify - reset notify registration chart correctly This patch fixes a minor bug in the notify driver unregistration process. The notify registration chart is an array and stores all the registered events in ascending order (dictates the notify event priorities). This array is compacted whenever an event is unregistered. The compaction is done shifting all the subsequent events to the left. Currently, the next element to the element being unregistered is not reset correctly, thereby leading to duplicate registrations in the array. This still leaves a valid duplicate event when that event is unregistered. This scenario happens when a lower event is unregistered while a higher event is also present.
