[PATCH 0/4] drm: Finally retire struct drm_format_name_buf

This is a cleanup patchset to remove drm_format_name_buf et al. There are two instances in drivers that need to be replaced with the %4cc printk format modifier. Patch 3 was left over back from an earlier patchset. [1] Patch 4 removes struct drm_format_name_buf. I built-tested with drm-tip. The pa

[PATCH 3/4] drm: Remove drm_get_format_name()

From: Sakari Ailus The %p4cc printk format modifier was recently added to print fourcc codes, replacing drm_get_format_name(). The function is no longer needed, so remove it. Signed-off-by: Sakari Ailus Reviewed-by: Petr Mladek Reviewed-by: Andy Shevchenko --- drivers/gpu/drm/drm_fourcc.c |

Introduce an RFC 4122 compliant UUID for the GPUs derived from the unique GPU serial number (from Vega10) on gpus. Where this serial number is not available, use a compliant random UUID. For virtualization, the unique ID is passed by the host driver in the PF2VF structure. Signed-off-by: Jiawei G

RE: [PATCH 2/2] drm/amdgpu/pm: add new fields for Navi1x

[AMD Public Use] Metrics table carries dynamic state information of the ASIC. There are other pp_* nodes which carry static information about min/max and levels supported and that is a one-time query. Why there is a need to put everything in metrics data? Thanks, Lijo -Original Message---

Re: [PATCH] drm/amdgpu: optimize to drop preamble IB for old GPUs

Well NAK, as discussed checking the global flag is more flexible since it will still enable the preamble drop when gfxoff is disabled. Christian. Am 17.05.21 um 06:39 schrieb Jiansong Chen: The optimization is safe for old GPUs and can help performance. Signed-off-by: Jiansong Chen Change-Id

RE: [PATCH] drm/amdgpu: optimize to drop preamble IB for old GPUs

[AMD Official Use Only] Doesn't current solution always enable the optimization in a safe and more clear way? 1. for gfx8/9/10 we use load_ce_ram in context_control to control the optimization. 2. for gfx6/7, we directly drop the preamble ib. Regards, Jiansong -Original Message- From:
