2016-03-01ARM: DRA7: hwmod: Add data for eDMA tpcc, tptc0, tptc1Peter Ujfalusi1-0/+88
Add hwmod data for the eDMA blocks: - TPCC: Third-party channel controller - TPTC0: Third-party transfer controller 0 - TPTC1: Third-party transfer controller 1 The TPCC's clock gating status follows the status of its clock and power domain. This means that the hwmod code can not directly control the TPCC enable/disable status.

2016-02-29KVM: arm/arm64: timer: Add active state cachingMarc Zyngier1-0/+1
Programming the active state in the (re)distributor can be an expensive operation so it makes some sense to try and reduce the number of accesses as much as possible. So far, we program the active state on each VM entry, but there is some opportunity to do less. An obvious solution is to cache the active state in memory, and only program it in the HW when conditions change. But because the HW can also change things under our feet (the active state can transition from 1 to 0 when the guest does an EOI), some precautions have to be taken, which amount to only caching an "inactive" state, and always programing it otherwise. With this in place, we observe a reduction of around 700 cycles on a 2GHz GICv2 platform for a NULL hypercall.

2016-02-29arm/arm64: KVM: Handle out-of-RAM cache maintenance as a NOPMarc Zyngier2-0/+21
So far, our handling of cache maintenance by VA has been pretty simple: Either the access is in the guest RAM and generates a S2 fault, which results in the page being mapped RW, or we go down the io_mem_abort() path, and nuke the guest. The first one is fine, but the second one is extremely weird. Treating the CM as an I/O is wrong, and nothing in the ARM ARM indicates that we should generate a fault for something that cannot end-up in the cache anyway (even if the guest maps it, it will keep on faulting at stage-2 for emulation). So let's just skip this instruction, and let the guest get away with it. Reviewed-by: Christoffer Dall <[email protected]> Signed-off-by: Marc Zyngier <[email protected]>
