linux-toradex.git/arch/sparc/kernel/hvcalls.S, branch v3.12.49 Linux kernel for Apalis and Colibri modules sparc64: T5 PMU 2014-10-31T14:10:17+00:00 bob picco bpicco@meloft.net 2014-09-16T14:09:06+00:00 666892deef1df8c41eddec4df90136fd368b97df commit 05aa1651e8b9ca078b1808a2fe7b50703353ec02 upstream. The T5 (niagara5) has different PCR related HV fast trap values and a new HV API Group. This patch utilizes these and shares when possible with niagara4. We use the same sparc_pmu niagara4_pmu. Should there be new effort to obtain the MCU perf statistics then this would have to be changed. Cc: sparclinux@vger.kernel.org Signed-off-by: Bob Picco <bob.picco@oracle.com> Signed-off-by: David S.

commit 05aa1651e8b9ca078b1808a2fe7b50703353ec02 upstream.

The T5 (niagara5) has different PCR related HV fast trap values and a new
HV API Group. This patch utilizes these and shares when possible with niagara4.

We use the same sparc_pmu niagara4_pmu. Should there be new effort to
obtain the MCU perf statistics then this would have to be changed.

sparc64: Add hypervisor interfaces for SPARC-T4 perf counter access. 2012-08-19T06:03:53+00:00 David S.

Therefore, access to them must go through a hypervisor interface. Signed-off-by: David S. Miller <davem@davemloft.net>

o Move all files from sparc64/kernel/ to sparc/kernel
  - rename as appropriate
o Update sparc/Makefile to the changes
o Update sparc/kernel/Makefile to include the sparc64 files

NOTE: This commit changes link order on sparc64!

Link order had to change for either of sparc32 and sparc64.
And assuming sparc64 see more testing than sparc32 change link
order on sparc64 where issues will be caught faster.
