Hi, I'm running netbsd-7 code on my new Lenovo T430 laptop. I'm using code from November 27 at the moment, with the DRM/KMS kernel, and there are a few glitches:
1) Sometimes the rendering of images e.g. in a web browser (firefox) is mangled / "interlaced" (not sure how to best describe it). Sometimes causing a re-paint fixes the glitch, sometimes it doesn't (by the looks of it). 2) Sometimes X11 appears to hang, and I get these messages in my kernel message buffer: drm: stuck on blitter ring drm: GPU HANG: ecode 2:0x87d0fff5, reason: Ring hung, action: reset drm: GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. drm: Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel drm: drm/i915 developers can then reassign to the right component if it's not a kernel issue. drm: The gpu crash dump is required to analyze gpu hangs, so please always attach it. drm: GPU crash dump saved to /sys/class/drm/card0/error i915drmkms0: interrupting at ioapic0 pin 16 (pci0@pci:0000:00:02.0) drm: Enabling RC6 states: RC6 on, RC6p on, RC6pp off (There's no GPU crash dump that I can find anywhere...) The hardware is probed by the kernel as: i915drmkms0 at pci0 dev 2 function 0: Intel Ivy Bridge Integrated Graphics Device (rev. 0x09) drm: Memory usable by graphics device = 2048M drm: Supports vblank timestamp caching Rev 2 (21.10.2013). drm: Driver supports precise vblank timestamp query. i915drmkms0: interrupting at ioapic0 pin 16 (i915) drm: GMBUS [i915 gmbus dpb] timed out, falling back to bit banging on pin 5 intelfb0 at i915drmkms0 i915drmkms0: info: registered panic notifier intelfb0: framebuffer at 0xffff800118fe6000, size 1600x900, depth 32, stride 6400 wsdisplay0 at intelfb0 kbdmux 1: console (default, vt100 emulation), using wskbd0 wsmux1: connecting to wsdisplay0 and pcictl says: 000:02:0: Intel Ivy Bridge Integrated Graphics Device (VGA display, revision 0x09) or 000:02:0: 0x01668086 (0x03000009) I'm about to update to newer netbsd-7 code (just updated my source tree), unless someone tells me "no-no, don't do that".
