* | | | iommu: Add DOMAIN_ATTR_PT_BASE_ADDR domain attributeMitchel Humpherys2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This attribute can be used to get the base address of the page tables for the given domain. This can be useful for some drivers that switch page tables around out-of-band (for example, per-process page tables managed by the GPU).

* | | | iommu: Add iommu_map_sg() functionOlav Haugan2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mapping and unmapping are more often than not in the critical path. map_sg allows IOMMU driver implementations to optimize the process of mapping buffers into the IOMMU page tables. Instead of mapping a buffer one page at a time and requiring potentially expensive TLB operations for each page, this function allows the driver to map all pages in one go and defer TLB maintenance until after all pages have been mapped. Additionally, the mapping operation would be faster in general since clients does not have to keep calling map API over and over again for each physically contiguous chunk of memory that needs to be mapped to a virtually contiguous region.

* | | | iommu/arm-smmu: add .domain_{set,get}_attr for coherent walk controlMitchel Humpherys2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under certain conditions coherent hardware translation table walks can result in degraded performance. Add a new domain attribute to disable/enable this feature in generic code along with the domain attribute setter and getter to handle it in the ARM SMMU driver.

Compiler inserts code that perform certain kinds of checks before operations that could cause UB. If check fails (i.e. UB detected) __ubsan_handle_* function called to print error message. So the most of the work is done by compiler. This patch just implements ubsan handlers printing errors. GCC has this capability since 4.9.x [1] (see -fsanitize=undefined option and its suboptions). However GCC 5.x has more checkers implemented [2]. Article [3] has a bit more details about UBSAN in the GCC.

Send notifications with level information that allows the registered drivers to easily determine the cluster level that is going in/out of power collapse. There is an issue with this implementation. GIC driver saves and restores the distributed registers as part of cluster notifications. On newer platforms there are multiple cluster levels are defined (e.g l2, cci etc). These cluster level notofications can happen independently. On MSM platforms GIC is still active while the cluster sleeps in idle, causing the GIC state to be overwritten with an incorrect previous state of the interrupts. This leads to a system hang. Do not save and restore on any L2 and higher cache coherency level sleep entry and exit.

Upon bus suspend, suspend interrupt kicks in otg state machine which moves device state to OTG_STATE_B_SUSPENDED from OTG_STATE_B_PERIPHERAL and decrements pm usage count. Upon cable unplug additional decrement of pm usage count is prevented. This state also takes care the handling of cable unplug followed by bus suspend interrupt. - Host initiated resume after bus suspend: Being in OTG_STATE_B_SUSPENDED after bus suspend, upon host initiated resume, wakeup interrupt kicks in otg state machine which moves device to OTG_STATE_B_PERIPHERAL state by incrementing pm usage count. - PC reboot with cable plugged in: After PC shutdown device goes to OTG_STATE_B_SUSPENDED state. After PC start power event irq thread kicks in otg state machine to move device to OTG_STATE_B_PERIPHERAL state and increments pm usage count. - Composition switch after bus suspend: dwc3_gadget_pullup() kicks in otg state machine to move device state from OTG_STATE_B_SUSPENDED to OTG_STATE_B_PERIPHERAL and increments pm usage count to prevent runtime suspend during device enumeration. Also, remove pm_runtime_set_active() which sets the PM runtime stauts as active to avoid pm_runtime_get_sync() failures which explicitly checks for runtime pm status. For example, if status is active, pm_runtime_get_sync() will just increments the counter without actually resuming the device.
