* gpu: nvgpu: Remove Pascal replayable fault supportTerje Bergstrom2018-07-09

* gpu: nvgpu: pmu: Fix pmu_state state updateDeepak Bhosale2018-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Commit c61e21c868246faf7a9ffc812590941fc362af17 fixed race codition in PMU state transition. - The race condition is such that PMU response(intr callback for messages) can run faster than kthread posting commands to PMU and thus PMU message callback may skip important pmu state change. - Commit c61e21c868246faf7a9ffc812590941fc362af17 introduced a fix where PMU state change was only updated from callback while other places can only update pmu_state variable - However, this commit introduced a regression as follows: - When PMU state is PMU_STATE_INIT_RECEIVED, we loop over every engine supported by GPU --> If state = PMU_STATE_INIT_RECEIVED, change the state to PMU_STATE_ELPG_BOOTING and init ELPG else If state != PMU_STATE_INIT_RECEIVED throw an error saying "PMU INIT not received" - Now, if GPU supports multiple engines, first engine will check that pmu_state is PMU_STATE_INIT_RECEIVED and change it to PMU_STATE_ELPG_BOOTING However, from second engine onwards, since state is already changed to PMU_STATE_ELPG_BOOTING, all engines except first engine start throwing error "PMU INIT not received" - This patch fixes the issue by changing pmu state from PMU_STATE_INIT_RECEIVED to PMU_STATE_ELPG_BOOTING only once.

* gpu: nvgpu: use devm variants to ioremapNitin Kumbhar2018-07-06
| | | | | | | | | | | | | | | | | | | | | | While removing nvgpu driver, devm mapped reg mappings are released on driver_unregister. For iGPU, these regs are explicitly unmapped with iounmap(). This results in "Trying to vfree() nonexistent vm area" warnings on driver removal. Address this by using devm* variants to map all IO regions of both iGPU and dGPU and let the driver unregister release these mappings. Also, lock out GPU regs in driver removal path.

This could lead to lower than expected effective frequency. Fixed the logic to adjust to nearest V/f point.
