Sample Code
|
||||
-----------
|
||||
Sample code for testing error injection can be found here:
|
||||
https://cgit.freedesktop.org/mesa/drm/tree/tests/amdgpu/ras_tests.c
|
||||
|
||||
This is part of the libdrm amdgpu unit tests which cover several areas of the GPU.
|
||||
There are four sets of tests:
|
||||
|
||||
RAS Basic Test
|
||||
|
||||
The test verifies the RAS feature enabled status and makes sure the necessary sysfs and debugfs files
|
||||
are present.
|
||||
|
||||
RAS Query Test
|
||||
|
||||
This test checks the RAS availability and enablement status for each supported IP block as well as
|
||||
the error counts.
|
||||
|
||||
RAS Inject Test
|
||||
|
||||
This test injects errors for each IP.
|
||||
|
||||
RAS Disable Test
|
||||
|
||||
This test tests disabling of RAS features for each IP block.
|
||||

Sample Code
|
||||
===========
|
||||
Sample code for testing error injection can be found here:
|
||||
https://cgit.freedesktop.org/mesa/drm/tree/tests/amdgpu/ras_tests.c
|
||||
|
||||
This is part of the libdrm amdgpu unit tests which cover several areas of the GPU.
|
||||
There are four sets of tests:
|
||||
|
||||
RAS Basic Test
|
||||
|
||||
The test verifies the RAS feature enabled status and makes sure the necessary sysfs and debugfs files
|
||||
are present.
|
||||
|
||||
RAS Query Test
|
||||
|
||||
This test checks the RAS availability and enablement status for each supported IP block as well as
|
||||
the error counts.
|
||||
|
||||
RAS Inject Test
|
||||
|
||||
This test injects errors for each IP.
|
||||
|
||||
RAS Disable Test
|
||||
|
||||
This test tests disabling of RAS features for each IP block.
