Re: [Qemu-devel] [PATCH RFC V4 0/4] Implement GIC-500 from GICv3 family for arm64

2015-09-24 Thread Pavel Fedin
Hello! Nice to see things moving on. I am waiting for PULL to be applied to master, and after this i'll be able to proceed with other things, including live migration. As part of it, i already rewrote state structure using bitops, so that it's free of CPU number restrictions. Would be nice if

[Qemu-devel] [PATCH RFC V4 0/4] Implement GIC-500 from GICv3 family for arm64

2015-09-17 Thread Shlomo Pongratz
From: Shlomo Pongratz This patch is a first step toward 128 cores support for arm64. At first only 64 cores are supported. This is because largest integer type has the size of 64 bits and modifying essential data structures in order to support 128 cores will require the usage of bitops. Things
