Subject: [PATCH v7 0/2] Add ThunderX2 SoC Performance Monitoring Unit driver
Date: Thu, 25 Oct 2018 05:59:15 +0000	[thread overview]
Message-ID: <20181025055833.28471-1-ganapatrao.kulkarni@cavium.com> (raw)

This patchset adds PMU driver for Cavium's ThunderX2 SoC UNCORE devices.
The SoC has PMU support in L3 cache controller (L3C) and in the
DDR4 Memory Controller (DMC).

v7:
	Incorporated review comments [3].
	Modified driver as loadable module.
	Updated Documentation with Event description.
	Removed per-channel(no SMC calls) sampling implementation(
	Since DMC and L3C channels are interleave, we have decided to
	sample channel zero and prorate it to account for a Device).

v6:
	Rebased to 4.18-rc1
	Updated with comments from John Garry[3]

v5:

v4:
	Incorporated review comments from Mark Rutland[1]

[2] https://lkml.org/lkml/2018/4/26/376

v3:

v2:
	Rebased to 4.12-rc1
	Removed Arch VULCAN dependency.
	Update SMC call parameters as per latest firmware.

v1:
	Initial patch
