Bug ID: 102204 Summary: GLideN64 very slow on oland/radeonsi Product: Mesa Version: 17.1 Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: aaronbpaden@gmail.com QA Contact: dri-devel@lists.freedesktop.org

I'm using: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland PRO [Radeon R7 240/340] Mesa: 17.1.6 Linux: 4.12.6

This is somewhat related to #98724.

I decided to give GLideN64 another try since it now works with Rogue Squadron, but I've found that while it does render (I wouldn't say that #98724 has been fixed. I just think that GLideN64/GLupeN64 no longer use glDrawElementsIndirect) it's still unplayably slow. The Windows drivers do work fine on the same hardware.

For this test, I was using the prebuilt and configured version found here: https://m64p.github.io/ the executable is mupen64plus-gui. Because of #97226 it has to be launched from the terminal.

The download link doesn't work with HTTPS Everywhere for some reason. Source is here: https://github.com/m64p/mupen64plus-GLideN64

Upgraded Kernel, xserver-xorg, Mesa, etc.

The problem disappears with "LIBGL_ALWAYS_SOFTWARE=1" and in more older versions of GLideN64 disappears with "MESA_EXTENSION_OVERRIDE=-GL_ARB_buffer_storage"

--- Comment #4 from H4nN1baL reizemberk@gmail.com --- This problem is currently "solved" on the GLide64 side. But it reveals a serious problem with GL_ARB_buffer_storage extension. GL_UNSIGNED_BYTE with GL_ARB_buffer_storage extension it's extremely slow. GL_UNSIGNED_SHORT with GL_ARB_buffer_storage extension is a little better but is still slow. GL_UNSIGNED_BYTE without GL_ARB_buffer_storage is faster, but not work at full speed. GL_UNSIGNED_SHORT without GL_ARB_buffer_storage works perfect.

The dangerous combination is GL_UNSIGNED_SHORT with GL_ARB_buffer_storage extension, that may end up destroying the hardware under the right conditions.

I quote myself:

Sorry for the delay, but I had a "technical mishap" ...my video card is DEAD, stone-dead. I am responsible for my unwise BIOS configuration (GART error reporting = Enabled + PCIE Spread Spectrum = Auto) and "pushing stress" on GPU to render at non-standard resolutions (monitor 1080p to 120Hz (max 144Hz), mupen64plus windowed to 1400x1050) using a buggy extension like some kind of "steeplechase generator" for benchmarking. Well, I reaped what I sowed.

This problem persist even on amdgpu (MSI Radeon RX 560 AERO ITX 4G OC). The problem not exist using nouveau (Gigabyte NVIDIA GeForce 210 GPU - GV-N210D3-1GI).
