Subject: [Qemu-devel] [PATCH v3 0/3] mips: add Global Interrupt Controller
Date: Mon, 28 Mar 2016 19:35:49 -0700 [thread overview]
Message-ID: <1459218952-9408-1-git-send-email-yongbok.kim@imgtec.com> (raw)
This patchset implement MIPS Global Interrupt Controller.
The Global Interrupt Controller (GIC) is responsible for mapping each
internal and external interrupt to the correct location for servicing.
Limitation:
Level triggering only
GIC CounterHi not implemented (Countbits = 32bits)
DINT not implemented
Local WatchDog, Fast Debug Channel, Perf Counter not implemented
It is based on the earlier un-merged GIC implementation.

v3:
* rebased to top of CPS changes
* removed GCR from the patchset as CPS patchset includes it
* added checking boundaries
* fixed racy code (James)
* split gic interval timer into separate file hw/timer/mips_gictimer.c
* updated review comments (James, Leon)
* cosmetic changes
v2:
* added user mode section (James)
* moved mips_gic.c into hw/intc, mips_gcr.c into hw/misc (PeterM, PeterC)
* renamed obvious duplications (Leon)
* renamed gic_irqs into irq_state (Leon)
* removed pointer to gic IRQs from env (Leon)
* fixed loading target_ulong CMGCRBase (Leon)
* removed unimplemented registers (Leon)
* fixed writing to wedge register (Leon)
* removed magic numbers
* updated usage of map_vp to indicate not mapped
* cosmetic changes and other review comments
