Subject: [Intel-gfx] [PATCH v3 0/2] DGFX mmap with rpm
Date: Fri, 9 Sep 2022 16:54:17 +0530 [thread overview]
Message-ID: <20220909112419.26901-1-anshuman.gupta@intel.com> (raw)
As per PCIe Spec Section 5.3.1.4.1
When pcie function is in d3hot state,
Configuration and Message requests are the only TLPs accepted by a
Function in the D3hot state. All other received Requests must be
handled as Unsupported Requests, and all received Completions
may optionally be handled as Unexpected Completions.
Therefore when gfx endpoint function is in d3 state, all pcie iomem
transaction requires to transition the pcie function in D0 state.
Implementation of handling i915_gem_object_pin_map will be handled in
different series.
