Re: [Intel-gfx] i915.fastboot bug report - not working on coreboot
Hello (IIRC, there is no VBT or INT 10H support yet in coreboot native video init) Regarding EDID, it's handled from intel_gma_init in coreboot/src/northbridge/intel/i945/gma.c. The only thing I see that could be linked to a preferred mode is in decode_edid from coreboot/src/lib/edid.c : if (edid[0x18] 0x02) { printk(BIOS_SPEW, First detailed timing is preferred timing\n); has_preferred_timing = 1; } (...) /* detailed timings */ printk(BIOS_SPEW, Detailed timings\n); has_valid_detailed_blocks = detailed_block(out, edid + 0x36, 0); if (has_preferred_timing !did_detailed_timing) has_preferred_timing = 0; /* not really accurate... */ Maybe disabling has_preferred_timing if there are no did_detailed_timing is wrong? I'm sorry but my understanding of coreboot video initialization is too limited. Gluglug, could you suggest someone that could help on that issue? Addressing it will enable i915.fastboot support. Jesse, if meanwhile you can send me fastboot patch to handle that, I will be happy to test it and report the result. (At the moment, even if i915.fastboot fails as reported above, I get some blinking in Xorg, which is resolved after going back and forth to a text console) Thanks Charles On Thu, Oct 30, 2014 at 5:34 PM, Jesse Barnes jbar...@virtuousgeek.org wrote: On Thu, 23 Oct 2014 16:44:26 -0400 Charles Devereaux intel...@guylhem.net wrote: [0.529733] [drm:intel_set_config_compute_mode_changes], modes are different, full mode set [0.529736] [drm:drm_mode_debug_printmodeline], Modeline 0: 0 54167 1024 1048 1184 1344 768 771 777 806 0x0 0xa [0.529740] [drm:drm_mode_debug_printmodeline], Modeline 11:1024x768 60 65000 1024 1048 1184 1344 768 771 777 806 0x48 0xa This looks like the issue.

Coreboot is starting a grub2 payload, which is in the appropriate vesa mode, and has option set gfxpayload=keep to pass it to the kernel. The 3.14.16 kernel start in the appropriate vesa mode, but there is some flickering at one time, which indicates the drivers tries to reinitialize the video card, before returning to this same mode. The kernel arguments are: nohz=on nmi_watchdog=0 pcie_aspm=force i915.semaphores=1 i915.fastboot=1 i915.i915_enable_rc6=7 i915.i915_enable_fbc=1 i915.lvds_downclock=1 thinkpad_acpi.force_load=1 thinkpad_acpi.brightness_enable=0 snd-hda-intel.index=0 snd_hda_intel.power_save=10 snd_hda_intel.model=thinkpad snd-hda-intel.probe_mask=0x103 snd-pcsp.index=1 btusb.reset=1 quiet root=/dev/sda1 The kernel .config has: CONFIG_DRM_I915=y CONFIG_DRM_I915_KMS=y CONFIG_DRM_I915_FBDEV=y # CONFIG_DRM_I915_PRELIMINARY_HW_SUPPORT is not set # CONFIG_DRM_I915_UMS is not set Is it possible to enable some kind of debugging of i915.fastboot to see why exactly the video is reinitialized? I didn't see any module option to do that in drivers/gpu/drm/i915/i915_drv.c Here are the dmesg showing the time spent.
