Fails to lauch X on laptop with Ryzen 7 4700U
by Chris Chiu 03 Feb '20

03 Feb '20

We are working with new laptops that have the Ryzen 7 4700U. It fails to launch X so I can only access via the virtual terminal. I tried with the latest mainline kernel and kernel from https://cgit.freedesktop.org/~agd5f/linux but no luck. I also boot the kernel with parameter amdgpu.exp_hw_support=1, but the system freezes after loading amdgpu and I can't even switch to the virtual terminal. I post the bug description and related information on https://gitlab.freedesktop.org/drm/amd/issues/… [View More]

[PATCH] drm: Remove PageReserved manipulation from drm_pci_alloc
by Chris Wilson 02 Feb '20

02 Feb '20

drm_pci_alloc/drm_pci_free are very thin wrappers around the core dma facilities, and we have no special reason within the drm layer to behave differently. In particular, since commit de09d31dd38a50fdce106c15abd68432eebbd014 Author: Kirill A. Shutemov <kirill.shutemov(a)linux.intel.com> Date: Fri Jan 15 16:51:42 2016 -0800 page-flags: define PG_reserved behavior on compound pages As far as I can see there's no users of PG_reserved on compound pages. Let's use … [View More]PF_NO_COMPOUND here. it has been illegal to combine GFP_COMP with SetPageReserved, so lets stop doing both and leave the dma layer to its own devices.

[PATCH v2 00/18] In order to readout DP SDPs, refactors the handling of DP SDPs
by Gwan-gyeong Mun 02 Feb '20

02 Feb '20

In order to readout DP SDPs (Secondary Data Packet: DP HDR Metadata Infoframe SDP, DP VSC SDP), it refactors handling DP SDPs codes. It adds new compute routines for DP HDR Metadata Infoframe SDP and DP VSC SDP. And new writing routines of DP SDPs (Secondary Data Packet) that uses computed configs. New reading routines of DP SDPs are added for readout. It adds a logging function for DP VSC SDP. When receiving video it is very useful to be able to log DP VSC SDP. This greatly simplifies … [View More]
