kernel panic messages
Hi, I try to using gpu hardware accelerate to play video from mplayer
(vdpau+uvd) . The machine architecture is sparc64,video card is radeon
HD7450,OS version is redhat7,kernel version is 3.10.0, mplayer version is
1.1-21,mesa version is 9.2.5-6. But everything is ok on X86 platforms, all
versions are the same.
The kernel panic occured when radeon call radeon_cs_ioctl to receive
the command stream from libdrm interface. and then radeon_cs_ib_chunk() call
radeon_uvd_cs_parse to parse the command.
First I thought this error maybe occured in a permanent position and
maybe the ioctl data or size mismatch between user space and kernel space ，I
set 1 to /sys/module/drm/para... to open drm debug switch , after I catch the
messages, the panic occur everywhere .the error context maybe after
RADEON_GEM_WAIT_IDLE? after RADEON_GEM_CREATE and so forth. so is not the data
stream error during ioctl.
And I check the changelog from 3.10 to 3.15, no patch about this.
Other, I run rpm -e mesa-vdpau-drivers to uninstall the devices driver
from mesa ,the mplayer can play video stably using cpu , when I install this
package,the blue screen is come out . and I must run mplayer -vo x11 to solve
the blue screen problem.
Because I am not clearly about the framework of the mesa-vdpau-driver
and uvd. Can anyone help me ? Thks
the error messages is below:
