Subject: [PATCH v9 0/5] Add driver for GSC controller
Date: Thu, 17 Feb 2022 17:22:43 +0200 [thread overview]
Message-ID: <20220217152248.1016134-1-alexander.usyskin@intel.com> (raw)
GSC is a graphics system controller, it provides
a chassis controller for graphics discrete cards.
There are two MEI interfaces in GSC: HECI1 and HECI2.
This series includes instantiation of the auxiliary devices for HECI2
and mei-gsc auxiliary device driver that binds to the auxiliary device.
The prinicpal user of this interface is the
Intel Graphics System Controller Firmware Update Library (IGSC FU)
(https://github.com/intel/igsc)
In v2 the platform device was replaced by the auxiliary device.
v3 is the rebase over drm-tip to make public CI running.
In v4 the not needed debug prints and empty line were removed,
'select' were replaced by 'depends on' in MEI Kconfig,
the new include file now listed in the MAINTATINERS file.
V5, rebase and add Greg KH Reviewed-by
V6, rebase and drop redundant assignments found by the kernel test robot.
V7, add Greg KH Reviewed-by to the individual patches
V8, address Tvrtko comments for i915
V9, rebase and address more Tvrtko comments, use drm error printing
