[Bug 105218] Regresion in 847d0a393d7f0f967f39302900d5330f32b804c8

https://bugs.freedesktop.org/show_bug.cgi?id=105218 Bug ID: 105218 Summary: Regresion in 847d0a393d7f0f967f39302900d5330f32b804c8 Product: Mesa Version: git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: blocker Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel(a)lists.freedesktop.org Reporter: dark_sylinc(a)yahoo.com.ar QA Contact: dri-devel(a)lists.freedesktop.org Our Terrain sample from Ogre 2.1 uses a compute shader to generate the shadows of the terrain, and later uses a special vs & ps to render the terrain. What's special about that sample over the rest (that run fine) are: 1. The compute shader that generates the shadows (https://bitbucket.org/sinbad/ogre/src/09181053ca69f4760b655c2eed5b5ca7d62fd…). The heigthmap is in format R16_UNORM, the generated shadows texture is in RGB10A2 2. A PS that generates the normals (https://bitbucket.org/sinbad/ogre/src/09181053ca69f4760b655c2eed5b5ca7d62fd…). The normals' texture are in RGB10A2 3. The VS has no vertex buffer bound, but rather relies on gl_VertexID and integer ops (https://bitbucket.org/sinbad/ogre/src/09181053ca69f4760b655c2eed5b5ca7d62fd…) and reads the heightmap. After commit 847d0a393d7f0f967f39302900d5330f32b804c8 and at least until latest from today, running this sample causes an entire system freeze: Mouse cursor is the only thing that responds. Keyboard does not respond, hard resetting is the only way and tends to corrupt files in the drive (This was painful to bisect). Before this commit the sample behaves as expected. My GPU is a Radeon RX 560 2GB I can provide a binary with the failing sample, or instructions on how to build from source (https://ogrecave.github.io/ogre/api/2.1/SettingUpOgreLinux.html). Whatever you need. I'm flagging this as blocker because of the security implications of freezing the entire system with ease.

[PATCH] drm/msm/dsi: Fix Clang enum-conversion warning in dsi_get_cmd_fmt
by Nathan Chancellor 01 Apr '18

01 Apr '18

Clang warns this value doesn't match what the function's return type is and it's right. This appears to be a copy paste error from dsi_get_vid_fmt. ../drivers/gpu/drm/msm/dsi/dsi_host.c:743:35: warning: implicit conversion from enumeration type 'enum dsi_vid_dst_format' to different enumeration type 'enum dsi_cmd_dst_format' [-Wenum-conversion] case MIPI_DSI_FMT_RGB666: return VID_DST_FORMAT_RGB666; ~~~~~~ ^~~~~~~~~~~~~~~~~~~~~ Fixes: a689554ba6ed ("drm/msm: Initial add DSI connector support") Signed-off-by: Nathan Chancellor <natechancellor(a)gmail.com> --- drivers/gpu/drm/msm/dsi/dsi_host.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/msm/dsi/dsi_host.c b/drivers/gpu/drm/msm/dsi/dsi_host.c index 0f7324a686ca..d729b2b4b66d 100644 --- a/drivers/gpu/drm/msm/dsi/dsi_host.c +++ b/drivers/gpu/drm/msm/dsi/dsi_host.c @@ -740,7 +740,7 @@ static inline enum dsi_cmd_dst_format dsi_get_cmd_fmt( switch (mipi_fmt) { case MIPI_DSI_FMT_RGB888: return CMD_DST_FORMAT_RGB888; case MIPI_DSI_FMT_RGB666_PACKED: - case MIPI_DSI_FMT_RGB666: return VID_DST_FORMAT_RGB666; + case MIPI_DSI_FMT_RGB666: return CMD_DST_FORMAT_RGB666; case MIPI_DSI_FMT_RGB565: return CMD_DST_FORMAT_RGB565; default: return CMD_DST_FORMAT_RGB888; } -- 2.16.3
