I am trying to set up VirtualGL + TurboVNC on Arch with the Plasma KDE desktop. The host is itself a VM using an passed through Intel P4600 IGD. I believe that the passthrough itself is successful as I see GL performance when running a desktop on display :0.
I am using glmark2 to check what is happening. As a measure, I get a score of around 2000 on the host, and 300 when using llvmpipe and similar when using vglrun. vglrun glinfo is reporting that its using the Intel Mesa driver (vs llvmpipe), so the set up at least looks okay, but it seems that vglrun is still using software rendering. Passing +v +tr to vglrun in both cases shows me the traces at the end of this post, which aligns with what I am seeing (highlighted yellow). I've also highlighted green some other lines which confuse me. I read this <https://sourceforge.net/p/virtualgl/mailman/message/31296895/> that indicated that Mesa isn't supported and in the docs that Arch's VirtiualGL package might be broken. I do not know if these apply here (or are still valid). Also when trying to accelerate the whole DE using exec vglrun plasmastart-x11 in my xstartup.turbovnc, I seem to get a broken desktop. I am not sure if this is related to the above but have mentioned it at as another data point (if its unrelated then tips to fix would be appreciated!). Thanks, vglrun traces: ==== on host ==== [VGL] NOTICE: Added /usr/lib to LD_LIBRARY_PATH [VGL] Shared memory segment ID for vglconfig: 131106 [VGL] VirtualGL v2.6.3 64-bit (Build 20200214) [VGL 0x92aa5780] XOpenDisplay (name=NULL dpy=0x557453a35740(:0) ) 0.335932 ms [VGL] dlopen (filename=libGL.so flag=4098[VGL] NOTICE: Replacing dlopen("libGL.so") with dlopen("libvglfaker.so") retval=0x7f2c935804f0) [VGL] Opening connection to 3D X server :0 [VGL] dlopen (filename=libGLX_mesa.so.0 flag=1 retval=0x557453a53170) [VGL] dlopen (filename=libGLX_mesa.so.0 flag=258 retval=0x557453a53170) [VGL] dlopen (filename=/usr/lib/dri/tls/i965_dri.so flag=258 retval=0x00000000) [VGL] dlopen (filename=/usr/lib/dri/i965_dri.so flag=258 retval=0x557453a69340) [VGL 0x92aa5780] glXGetProcAddressARB ((char *)procName=glXSwapIntervalEXT [INTERPOSED]) 0.005960 ms [VGL 0x92aa5780] glXChooseFBConfig (dpy=0x557453a35740(:0) screen=0 attrib_list=[0x8012=0x0001 0x8010=0x0001 0x8011=0x0001 0x0022=0x8002 0x0008=0x0001 0x0009=0x0001 0x000a=0x0001 0x000b=0x0001 0x000c=0x0001 0x000d=0x0000 0x0002=0x0001 0x0005=0x0001 ] glxattribs=[0x8010=0x0001 0x000c=0x0001 0x000d=0x0000 0x0002=0x0001 0x0005=0x0001 0x0008=0x0001 0x0009=0x0001 0x000a=0x0001 0x000b=0x0001 0x8011=0x0001 0x0022=0x8002 ] [VGL] dlopen (filename=libGLX_mesa.so.0 flag=258 retval=0x557453a53170) [VGL] dlopen (filename=/usr/lib/dri/tls/i965_dri.so flag=258 retval=0x00000000) [VGL] dlopen (filename=/usr/lib/dri/i965_dri.so flag=258 retval=0x557453a69340) configs[0]=0x557453b9a040(0x67) configs[1]=0x557453b9a7c0(0x6f) configs[2]=0x557453b9af40(0x77) configs[3]=0x557453b9b300(0x7b) configs[4]=0x557453b9bc60(0x85) configs[5]=0x557453b9c3e0(0x8d) configs[6]=0x557453b9bd50(0x86) configs[7]=0x557453b9c4d0(0x8e) configs[8]=0x557453b9b030(0x78) configs[9]=0x557453b9b3f0(0x7c) configs[10]=0x557453b9fa40(0xc7) configs[11]=0x557453b9fe00(0xcb) configs[12]=0x557453b9ffe0(0xcd) configs[13]=0x557453ba00d0(0xce) *nelements=14 ) 6.473064 ms [VGL 0x92aa5780] glXGetFBConfigAttrib (dpy=0x557453a35740(:0) config=0x557453b9a040(0x67) attribute=2(0x2) *value=32(0x20) ) 0.008106 ms ==== on tvnc ==== [VGL] NOTICE: Added /usr/lib to LD_LIBRARY_PATH [VGL] Shared memory segment ID for vglconfig: 131076 [VGL] VirtualGL v2.6.3 64-bit (Build 20200214) [VGL 0x9f624780] XOpenDisplay (name=NULL dpy=0x555b28562740(:1) ) 2.894163 ms [VGL] dlopen (filename=libGL.so flag=4098[VGL] NOTICE: Replacing dlopen("libGL.so") with dlopen("libvglfaker.so") retval=0x7f90a00ff4f0) [VGL] Opening connection to 3D X server :0 [VGL] dlopen (filename=libGLX_mesa.so.0 flag=1 retval=0x555b28583a20) [VGL] dlopen (filename=libGLX_mesa.so.0 flag=258 retval=0x555b28583a20) [VGL] dlopen (filename=/usr/lib/dri/tls/i965_dri.so flag=258 retval=0x00000000) [VGL] dlopen (filename=/usr/lib/dri/i965_dri.so flag=258 retval=0x555b285964a0) [VGL 0x9f624780] glXGetProcAddressARB ((char *)procName=glXSwapIntervalEXT [INTERPOSED]) 0.045061 ms [VGL 0x9f624780] glXChooseFBConfig (dpy=0x555b28562740(:1) screen=0 attrib_list=[0x8012=0x0001 0x8010=0x0001 0x8011=0x0001 0x0022=0x8002 0x0008=0x0001 0x0009=0x0001 0x000a=0x0001 0x000b=0x0001 0x000c=0x0001 0x000d=0x0000 0x0002=0x0001 0x0005=0x0001 ] glxattribs=[0x8010=0x0001 0x000c=0x0001 0x000d=0x0000 0x0002=0x0001 0x0005=0x0001 0x0008=0x0001 0x0009=0x0001 0x000a=0x0001 0x000b=0x0001 0x8011=0x0001 0x0022=0x8002 ] [VGL] dlopen (filename=libGLX_mesa.so.0 flag=258 retval=0x555b28583a20) [VGL] dlopen (filename=/usr/lib/dri/tls/swrast_dri.so flag=258 retval=0x00000000) [VGL] dlopen (filename=/usr/lib/dri/swrast_dri.so flag=258 retval=0x555b28705370) configs[0]=0x555b286c7170(0x67) configs[1]=0x555b286c78f0(0x6f) configs[2]=0x555b286c8070(0x77) configs[3]=0x555b286c8430(0x7b) configs[4]=0x555b286c8d90(0x85) configs[5]=0x555b286c9510(0x8d) configs[6]=0x555b286c8e80(0x86) configs[7]=0x555b286c9600(0x8e) configs[8]=0x555b286c8160(0x78) configs[9]=0x555b286c8520(0x7c) configs[10]=0x555b286ccb70(0xc7) configs[11]=0x555b286ccf30(0xcb) configs[12]=0x555b286cd110(0xcd) configs[13]=0x555b286cd200(0xce) *nelements=14 ) 44.402122 ms [VGL 0x9f624780] glXGetFBConfigAttrib (dpy=0x555b28562740(:1) config=0x555b286c7170(0x67) attribute=2(0x2) *value=32(0x20) ) 0.003815 ms -- You received this message because you are subscribed to the Google Groups "VirtualGL User Discussion/Support" group.
