* | msm: kgsl: Allow draw context to perform only replay on recoveryHareesh Gundu2017-04-23
|/ | | | | | | | | | | | | | | | | Robust context attempts to perform a rendering that takes too long whether due to an infinite loop in a shader or even just a rendering operation that takes too long on the given hardware. This type of attempts can result into GPU faults. Robust context expect driver to replay IB instead skip IB and if it fails on replay context has to be invalidated. KGSL_CONTEXT_INVALIDATE_ON_FAULT flag allows draw context to execute only replay policy on GPU fault recovery instead of going to default recovery policy. User space has to set this flag during the context creation. Change-Id: If42dc5afc7d5ed1226b73ae5abfa2648d7acf2c3 Signed-off-by: Hareesh Gundu <hareeshg@codeaurora.org>

| * msm: kgsl: Remove incorrect check to cap AB vote to IB voteDeepak Kumar2017-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For dual channel DDR, IB vote from client is half of actual IB vote as IB vote calculation on client side doesn't consider number of DDR channels. ICB driver takes care of multiplying the client IB vote with number of DDR channels. This change removes the AB capping check to avoid the scenarios where AB vote > actual IB vote/2 but gets capped to actual IB vote/2 because client side IB vote is half of actual IB vote. Removal of this check will not impact single channel DDR targets because of the way AB value is calculated. In case of honest BW voting, AB will always be less than IB as AB calculation doesn't consider RAM wait value. In case of unhonest vote, AB value is always caluclated as some percentage of IB vote and this percentage value is always <=100%.

* / msm: kgsl: Fix false timeout gpu faultsHareesh Gundu2017-02-15
|/ | | | | | | | | | | | | | | | | | | | Sometimes ringbuffer timer is not getting updated due to race with the preemption. This can cause dispatcher to detect false timeout gpu faults. Remove preempt state check in adreno_dispatch_process_drawqueue(), which will allow to update ringbuffer timeout value irrespective of the preemption state. If the preemption completes successfully, preemption logic updates timer for new_rb. We don’t need to care if it is not updated for prev_rb. If preemption in-progress timer will be updated for cur_rb in adreno_dispatch_process_drawqueue(). In both cases we are taking care to update ringbuffer timer. Hence we don’t need to check preemption state. CRs-Fixed: 1095344 Change-Id: I0e0ec655e2262c4f499748ce35a8d710ed15b5e3 Signed-off-by: Hareesh Gundu <hareeshg@codeaurora.org>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current irq handler clears the pending interrupt bits in interrupt status register before serving the interrupts. This leads to a race condition with the idle check which checks the interrupt status register to determine whether any interrupt is pending or not. As the interrupt status register is already cleared, idle check goes ahead and switch off the GPU clocks even when irq is yet to be served causing NOC errors. This change refcounts each irq handler call and uses this reference count to determine if any irq is still pending or not along with interrupt status register to avoid this race condition.
