[Qemu-devel] [PATCH 0/4] target-arm: Implement support for generic timer

From: Peter Maydell
Subject: [Qemu-devel] [PATCH 0/4] target-arm: Implement support for generic timers
Date: Tue, 30 Jul 2013 18:55:29 +0100

This patch series implements support for the 'generic timers',
which are a set of timers defined in the ARM Architecture Reference
Manual and implemented by the Cortex-A15. We've got away without
these up til now because Linux will generally fall back on whatever
random timer is present on the devboard if it can't find the
on-CPU timers, but this is less than ideal. (Among other things,
the proposed mach-virt should just use the generic timers so it
doesn't have to provide an sp804 timer.)

Peter Maydell (4):
  target-arm: Allow raw_read() and raw_write() to handle 64 bit regs
  target-arm: Support coprocessor registers which do I/O
  target-arm: Implement the generic timer
  hw/cpu/a15mpcore: Wire generic timer outputs to GIC inputs
