* | | drivers: GICv3: Add mb() after the read of the IAR1_EL1 and other registersAbhimanyu Kapur2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per the GICv3 architecture spec section "Observability of GIC Register Accsses", architecture execution of the "DSB" gurantees that last interrupt identifier read from ICC_IAR{0,1}_EL1 is observable by the top-level Distributor and by accesses from any processor to the top-level Distributor. Same comment goes for the ICC_PMR_EL1 and ICC_SGI1R_EL1 too.

* | | arm: traps: emulate a MRCC instruction reading CNTPCT registerSe Wang (Patrick) Oh2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A user space application is planned to support feature for synchronized timestamp among debug packets across peripherals. As part of the feature, it is responsible for providing physical timer count value to user space. If memory mapped timer is used in ARM arch, Usersapce can't read the physical timer count directly with a MRCC ASM instruction. So Kernel traps the instruction and returns the physical timer count.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Existing PSCI implementation supports platform coordinated means of low power modes where cluster low power modes are aggregated at the platform level. Adding support for OS initiated scheme, where is OS is responsible for selecting cluster low power modes based on last man determination. With OS initiated scheme, the OS can make better cluster decisions based on wakeup times of CPUs within a cluster. To this effect, in OS initiated schemes, the composite state ID is computed by the idle driver before calling into the cpu_suspend API. The PSCI driver is modified to use the composite ID to distinguish between retention and non-retention states.

* | | cpu_pm: Add level to the cluster pm notificationMurali Nalajala2016-03-22

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver change in commit 96f92e28e035 ("usb: dwc3-msm: Use hs phy and ss phy irq as wake up source") favored using hs_phy_irq over pwr_event_irq to wake up USB out of suspend.

We want to optimize such as to have as much direct mapped memory as possible since there is penalty for mapping/unmapping highmem. Now, we may have an image that is expected to have a lifetime of the entire system and is reserved in physical region that would be part of direct mapped lowmem. The physical memory which is thus reserved is never used by Linux. This means that even though the system is not actually accessing the virtual memory corresponding to the reserved physical memory, we are still losing that portion of direct mapped lowmem space. So by allowing lowmem to be non contiguous we can give this unused virtual address space of reserved region back for use in vmalloc.
