By default/after a system reboot<br> the GMUX connect the AMD GPU to the available displays. Consequently, the<br> hybrid setup should not cause any additional issues. For example, the Intel GPU<br> seems to be not powered, because it is not even enumerated.<br> <br> lspci tells me:<br> > 01:00.0 VGA compatible controller: Advanced Micro Devices,<br> > Inc.

Baffin [Radeon RX 460]<br> <br> The amdgpu driver in linux-4.9-rc6 (+ polaris11 firmware from<br> the firmware-amd-graphics Debian package) detects the card, but the system<br> crashes in the later stages of probing/initializing the driver (see attached<br> dmesg_gpuamd2.txt).<br> <br> Indeed it seems that there is a divison by zero encountered in:<br> drivers/gpu/drm/amd/powerplay/smumgr/polaris10_smc.c:1918<br> <br> > t_diff1 = hwmgr->thermal_controller.advanceFanControlParameters.usTMed -<br> > hwmgr->thermal_controller.advanceFanControlParameters.usTMin;<br> > t_diff2 = hwmgr->thermal_controller.advanceFanControlParameters.usTHigh -<br> > hwmgr->thermal_controller.advanceFanControlParameters.usTMed;<br> .<br> .<br> > slope1 = (uint16_t)((50 + ((16 * duty100 * pwm_diff1) / t_diff1)) / 100);<br> > slope2 = (uint16_t)((50 + ((16 * duty100 * pwm_diff2) / t_diff2)) / 100);<br> <br> t_diff1 and t_diff2 are zero; probably because active cooling by fans<br> is realized<br> quite differently in this embedded/laptop version of the graphics card.<br> <br> When commenting this simply out, the driver loads and I can run an X<br> server .. for a while; even glxgears as well as glxinfo seem to run fine.<br> However after some time or possibly after certain actions (e.g., on one occasion<br> when I set a terminal window to full-screen) the screen blanks out and the<br> system becomes sometimes completely unresponsive.<br> <br> On one of the more partial system crashes I could still read dmesg<br> (see attached<br> dmesg_gpuamd3.txt also detailing the log messages before):<br> > [ 273.877708]<br> > failed to send message 5e ret is 0<br> > [ 286.343630]<br> > failed to send message 5e ret is 0<br> > [ 906.960345] amdgpu 0000:01:00.0: GPU fault detected: 146 0x04121014<br> > [ 906.960348] amdgpu 0000:01:00.0:<br> > VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x0010CE82<br> > [ 906.960349] amdgpu 0000:01:00.0:<br> > VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0D010014<br> > [ 906.960350] VM fault (0x14, vmid 6) at page 1101442, write from<br> > 'CB3' (0x43423300) (16)<br> <br> Again, any help/advice/pointers highly appreciated!<br> <br> Greetings,<br> Bernhard<br> <br> [1] <a href="http://www.amd.com/en-us/press-releases/Pages/radeon-pro-400-2016oct27.aspx" id="LPlnk475851" previewremoved="true"> http://www.amd.com/en-us/press-releases/Pages/radeon-pro-400-2016oct27.aspx</a> <div id="LPBorder_GT_14801185288400.7274598424829852" style="margin-bottom: 20px; overflow: auto; width: 100%; text-indent: 0px;"> <table id="LPContainer_14801185288360.03182244988533389" cellspacing="0" style="width: 90%; background-color: rgb(255, 255, 255); position: relative; overflow: auto; padding-top: 20px; padding-bottom: 20px; margin-top: 20px; border-top: 1px dotted rgb(200, 200, 200); border-bottom: 1px dotted rgb(200, 200, 200);"> <tbody> <tr valign="top" style="border-spacing: 0px;"> <td id="ImageCell_14801185288370.7028237433065467" colspan="1" style="width: 250px; position: relative; display: table-cell; padding-right: 20px;"> <div id="LPImageContainer_14801185288370.5936617779712585" style="background-color: rgb(255, 255, 255); height: 31px; position: relative; margin: auto; display: table; width: 132px;"> <a id="LPImageAnchor_14801185288380.5263715534287636" href="http://www.amd.com/en-us/press-releases/Pages/radeon-pro-400-2016oct27.aspx" target="_blank" style="display: table-cell; text-align: center;"><img aria-label="Preview image with link selected.
