Alright, I've found a Dell Latitude D620, which has a physical serial port and Intel 945 integrated graphics. The eglgears demo runs when built from Genode 14.05, and I can see from the console output that it's hardware accelerated. So that's great!
My guess is that the fastest way I can prototype separating the driver into its own address space is to modify the old linux_drivers code, rather than trying to port the modern Intel driver from a current Linux kernel release. But I'd prefer to work against Genode master, if that isn't too much work to throw at a prototype. What would it take to forward-port the old linux_drivers code from 2010 into dde_linux on current Genode master? (Or should I just build a throwaway demo against 14.05 to prove the concept, and help with porting the modern Intel driver later?) As one experiment in that direction, I tried running eglgears built from Genode 14.11, which I guess was the last release that had dde_kit. Even with the patch to not free a static array, it opens a blank window. The console output stops after these messages: [init -> launchpad -> init -> eglgears] native_probe* native_create_probe(EGLNativeDisplayType): not yet implemented dpy=0 [init -> launchpad -> init -> eglgears] native_probe_result native_get_probe_result(native_probe*): not yet implemented [init -> launchpad -> init -> nit_fb] using xywh=(300,300,576,408) On the 14.05 release, where the demo works, the output continues past that. It starts with: [init -> launchpad -> init -> nit_fb] using xywh=(300,100,576,408) refresh_rate=0 [init -> launchpad -> init -> eglgears] native_probe* native_create_probe(EGLNativeDisplayType): not yet implemented dpy=0 [init -> launchpad -> init -> eglgears] native_probe_result native_get_probe_result(native_probe*): not yet implemented [init -> launchpad -> init -> eglgears] I915_gpu_driver::I915_gpu_driver(): module_agp_intel_init returned 0, driver at 14e27a0 [init -> launchpad -> init -> eglgears] dev_info: Intel 945GM Chipset [init -> launchpad -> init -> eglgears] dev_info: detected 7932K stolen memory [init -> launchpad -> init -> eglgears] dev_info: AGP aperture is 256M @ 0xd0000000 [init -> launchpad -> init -> eglgears] I915_gpu_driver::I915_gpu_driver(): call drm_agp_init Plus another 20 lines or so. Any idea why it's failing?
