Summary: [r300] lock Xserver by moving window
Product: DRI
Version: DRI CVS
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: General
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
I am able to lock Xserver on r300 and current Mesa in few easy steps:
1) start my application
2) move window application with mouse
3) quit the application
Application renders one frame - few textured rectangles, then waits for key.
If I disable rendering or if I won't move window with mouse - application
closes correctly.
I was able to use gdb from second machine.
First, Xserver (I needed to use ctrl+c):
#0 0xb7f91410 in __kernel_vsyscall ()
#1 0xb7e30179 in ioctl () from /lib/libc.so.6
#2 0xb7befa55 in drmGetLock () from /usr/lib/libdrm.so.2
#3 0xb7f8287f in DRILock () from /usr/lib/xorg/modules/extensions//libdri.so
#4 0xb7f828fa in DRIDoWakeupHandler ()

#7 0x0819a114 in WaitForSomething ()
#8 0x08086621 in Dispatch ()
#9 0x0806e579 in main ()
Then top of my application backtrace:
