drm/amdgpu: add another ATPX quirk for TOPAZ

2018-07-18T13:48:22+00:00

Needs ATPX rather than _PR3. Bug: https://bugzilla.kernel.org/show_bug.cgi?id=200517 Reviewed-by: Junwei Zhang Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/amdgpu: Add amdgpu_atpx_get_dhandle()

2018-06-28T20:32:18+00:00

Since it seems that some vendors are storing the ATIF ACPI methods under the same handle that ATPX lives under instead of the device's own handle, we're going to need to be able to retrieve this handle later so we can probe for ATIF there.

Revert "drm/amdgpu: Add an ATPX quirk for hybrid laptop"

2018-06-01T14:45:19+00:00

This reverts commit 13b40935cf64f59b93cf1c716a2033488e5a228c. This was a workaround for a bug in the HDA driver that prevented the HDA audio chip from going into runtime pm which prevented the GPU from going into runtime pm.

drm/amdgpu: fix amdgpu_atpx_get_client_id()'s return type

2018-05-15T18:43:50+00:00

The method struct vga_switcheroo_handler::get_client_id() is defined as returning an 'enum vga_switcheroo_client_id' but the implementation in this driver, amdgpu_atpx_get_client_id(), returns an 'int'. Fix this by returning 'enum vga_switcheroo_client_id' in this driver too. Signed-off-by: Luc Van Oostenryck Signed-off-by: Alex Deucher

drm/amdgpu: fix check for port PM availability

2016-11-29T14:23:39+00:00

The ATPX method does not always exist on the dGPU, it may be located at the iGPU. The parent device of the iGPU is the root port for which bridge_d3 is false. This accidentally enables the legacy PM method which conflicts with port PM and prevented the dGPU from powering on.

drm/amdgpu: fix power state when port pm is unavailable

2016-11-23T18:57:14+00:00

When PCIe port PM is not enabled (system BIOS is pre-2015 or the pcie_port_pm=off parameter is set), legacy ATPX PM should still be marked as supported. Otherwise the GPU can fail to power on after runtime suspend. This affected a Dell Inspiron 5548. Ideally the BIOS date in the PCI core is lowered to 2013 (the first year where hybrid graphics platforms using power resources was introduced), but that seems more risky at this point and would not solve the pcie_port_pm=off issue.
