2020-07-01	drm/amdkfd: Support debugger in Navi1x trap handler	Jay Cornwall
	- Preserve scalar GPRs ttmp[4:11] and ttmp13 - Add single step exception during context save workaround - Remove incorrect PC adjustment during context save Signed-off-by: Jay Cornwall <jay.cornwall@amd.com> Reviewed-by: Yong Zhao <Yong.Zhao@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2020-07-01	drm/amdkfd: Support newer assemblers in gfx10 trap handler	Jay Cornwall
	The contents of macros are parsed by the assembler before conditions have been tested. This causes assembly errors when using IP-specific instructions in the IP-unified trap handler. Add a preprocessing step to filter IP-specific code. Also guard a Navi1x-specific instruction (no effect on Sienna_Cichlid).

2019-09-16	drm/amdkfd: Swap trap temporary registers in gfx10 trap handler	Jay Cornwall
	ttmp[4:5] hold information useful to the debugger. Use ttmp[14:15] instead, aligning implementation with gfx9 trap handler. Signed-off-by: Jay Cornwall <jay.cornwall@amd.com> Reviewed-by: shaoyun liu <Shaoyun.liu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
