Here's an updated patch set for core DRM + i915 mode setting. I spent a good part of the day trying to reduce the size of the patches against the core, so things should be nearly reviewable now. I'm still tracking down the unload/load bug (was hoping the diff reduction + audit would magically fix it, but alas). This patchset sits on top of 2db46b5668dfed59acacd75dfc49ecf947ea5aeb from the anholt's drm-intel-next branch. It should work well enough to set an initial mode and let you play around with it if you do 'modprobe i915 modeset=1' to load it. Comments & review appreciated. Thanks, Jesse |

FYI, I updated the patchset today and fixed the load/unload crasher, so I'm moving on to the other tasks now (getting X solid, etc). Latest patches are at http://www.kernel.org/pub/linux/kernel/people/jbarnes/patches/kms-3. Thanks, Jesse |

This should probably go directly in i915_irq.c (would we ever not be interested in the hotplug interrupts, or be concerned about the rate they come in in that case?), or otherwise use the pipestat update function that we've got now. -- Eric Anholt er...@an... eri...@in... |

I think it creates a table that the userland module utilities can look at to see which drivers go with each device.

Hm, looks like lies. Fixed. Clearly we need the HWS page to be set up no matter what in the KMS case, which we do.

Here's an updated set that incorporates Eric's feedback, along with a few other fixes: - lastclose now correctly restores the mode (useful for if an application crashes or doesn't clean up after itself) - SysRq-g allows you to switch to the graphics console - X driver works again (had some merge errors in the master rework) - my test programs work again - Wayland and Eagle work on top of this code So please review. Rip it apart. Fix bugs. Add features. At some point this will be merged into drm-next and we can start piling stuff on top rather than relying on me to respin & rebase all the time. -- Jesse Barnes, Intel Open Source Technology Center Jesse Barnes (3): DRM: rework master design DRM: add mode setting support DRM: i915: add mode setting support drivers/gpu/drm/Kconfig | 11 + drivers/gpu/drm/Makefile | 3 +- drivers/gpu/drm/drm_auth.c | 29 +- drivers/gpu/drm/drm_bufs.c | 20 +- drivers/gpu/drm/drm_context.c | 10 +- drivers/gpu/drm/drm_crtc.c | 2500 ++++++++++++++++++++++++++++++++ drivers/gpu/drm/drm_crtc_helper.c | 822 +++++++++++ drivers/gpu/drm/drm_drv.c | 76 +- drivers/gpu/drm/drm_edid.c | 732 ++++++++++ drivers/gpu/drm/drm_fops.c | 223 ++-- drivers/gpu/drm/drm_ioctl.c | 57 +- drivers/gpu/drm/drm_irq.c | 64 +- drivers/gpu/drm/drm_lock.c | 42 +- drivers/gpu/drm/drm_mm.c | 1 + drivers/gpu/drm/drm_modes.c | 574 ++++++++ drivers/gpu/drm/drm_proc.c | 8 +- drivers/gpu/drm/drm_stub.c | 149 ++- drivers/gpu/drm/drm_sysfs.c | 329 +++++- drivers/gpu/drm/i915/Makefile | 17 +- drivers/gpu/drm/i915/dvo.h | 151 ++ drivers/gpu/drm/i915/dvo_ch7017.c | 454 ++++++ drivers/gpu/drm/i915/dvo_ch7xxx.c | 368 +++++ drivers/gpu/drm/i915/dvo_ivch.c | 442 ++++++ drivers/gpu/drm/i915/dvo_sil164.c | 302 ++++ drivers/gpu/drm/i915/dvo_tfp410.c | 335 +++++ drivers/gpu/drm/i915/i915_dma.c | 343 ++++- drivers/gpu/drm/i915/i915_drv.c | 35 + drivers/gpu/drm/i915/i915_drv.h | 53 +- drivers/gpu/drm/i915/i915_gem.c | 134 ++- drivers/gpu/drm/i915/i915_irq.c | 55 +- drivers/gpu/drm/i915/i915_mem.c | 3 +- drivers/gpu/drm/i915/intel_bios.c | 193 +++ drivers/gpu/drm/i915/intel_bios.h | 405 ++++++ drivers/gpu/drm/i915/intel_crt.c | 284 ++++ drivers/gpu/drm/i915/intel_display.c | 1621 +++++++++++++++++++++ drivers/gpu/drm/i915/intel_drv.h | 146 ++ drivers/gpu/drm/i915/intel_dvo.c | 501 +++++++ drivers/gpu/drm/i915/intel_fb.c | 927 ++++++++++++ drivers/gpu/drm/i915/intel_i2c.c | 184 +++ drivers/gpu/drm/i915/intel_lvds.c | 525 +++++++ drivers/gpu/drm/i915/intel_modes.c | 87 ++ drivers/gpu/drm/i915/intel_sdvo.c | 1127 ++++++++++++++ drivers/gpu/drm/i915/intel_sdvo_regs.h | 327 +++++ drivers/gpu/drm/i915/intel_tv.c | 1725 ++++++++++++++++++++++ drivers/gpu/drm/radeon/r300_cmdbuf.c | 11 +- drivers/gpu/drm/radeon/radeon_cp.c | 73 +- drivers/gpu/drm/radeon/radeon_drv.h | 14 +- drivers/gpu/drm/radeon/radeon_state.c | 166 ++- drivers/video/console/vgacon.c | 17 + include/drm/Kbuild | 2 +- include/drm/drm.h | 24 + include/drm/drmP.h | 87 +- include/drm/drm_crtc.h | 737 ++++++++++ include/drm/drm_crtc_helper.h | 121 ++ include/drm/drm_edid.h | 202 +++ include/drm/drm_mode.h | 278 ++++ include/drm/i915_drm.h | 2 +- include/linux/console.h | 4 + 58 files changed, 17679 insertions(+), 453 deletions(-) create mode 100644 drivers/gpu/drm/drm_crtc.c create mode 100644 drivers/gpu/drm/drm_crtc_helper.c create mode 100644 drivers/gpu/drm/drm_edid.c create mode 100644 drivers/gpu/drm/drm_modes.c create mode 100644 drivers/gpu/drm/i915/dvo.h create mode 100644 drivers/gpu/drm/i915/dvo_ch7017.c create mode 100644 drivers/gpu/drm/i915/dvo_ch7xxx.c create mode 100644 drivers/gpu/drm/i915/dvo_ivch.c create mode 100644 drivers/gpu/drm/i915/dvo_sil164.c create mode 100644 drivers/gpu/drm/i915/dvo_tfp410.c create mode 100644 drivers/gpu/drm/i915/intel_bios.c create mode 100644 drivers/gpu/drm/i915/intel_bios.h create mode 100644 drivers/gpu/drm/i915/intel_crt.c create mode 100644 drivers/gpu/drm/i915/intel_display.c create mode 100644 drivers/gpu/drm/i915/intel_drv.h create mode 100644 drivers/gpu/drm/i915/intel_dvo.c create mode 100644 drivers/gpu/drm/i915/intel_fb.c create mode 100644 drivers/gpu/drm/i915/intel_i2c.c create mode 100644 drivers/gpu/drm/i915/intel_lvds.c create mode 100644 drivers/gpu/drm/i915/intel_modes.c create mode 100644 drivers/gpu/drm/i915/intel_sdvo.c create mode 100644 drivers/gpu/drm/i915/intel_sdvo_regs.h create mode 100644 drivers/gpu/drm/i915/intel_tv.c create mode 100644 include/drm/drm_crtc.h create mode 100644 include/drm/drm_crtc_helper.h create mode 100644 include/drm/drm_edid.h create mode 100644 include/drm/drm_mode.h |

Add mode setting support to the DRM layer. This is a fairly big chunk of work that allows DRM drivers to provide full output control and configuration capabilities to userspace. It was motivated by several factors: - the fb layer's APIs aren't suited for anything but simple configurations - coordination between the fb layer, DRM layer, and various userspace drivers is poor to non-existent (radeonfb excepted) - user level mode setting drivers makes displaying panic & oops messages more difficult - suspend/resume of graphics state is possible in many more configurations with kernel level support This commit just adds the core DRM part of the mode setting APIs. Driver specific commits using these new structure and APIs will follow.

This commit adds i915 driver support for the DRM mode setting APIs. Currently, VGA, LVDS, SDVO DVI & VGA, TV and DVO LVDS outputs are supported. HDMI, DisplayPort and additional SDVO output support will follow. Support for the mode setting code is controlled by the new 'modeset' module option. A new config option, CONFIG_DRM_I915_KMS controls the default behavior, and whether a PCI ID list is built into the module for use by user level module utilities. Note that if mode setting is enabled, user level drivers that access display registers directly or that don't use the kernel graphics memory manager will likely corrupt kernel graphics memory, disrupt output configuration (possibly leading to hangs and/or blank displays), and prevent panic/oops messages from appearing. So use caution when enabling this code; be sure your user level code supports the new interfaces. A new SysRq key, 'g', provides emergency support for switching back to the kernel's framebuffer console; which is useful for testing.

Ah good; those bits should have been part of the master rework anyway. I think I was seeing lockups in the 2D driver w/o these changes, I'll update and re-test. Jesse |

I just pushed an updated set of commits to git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/drm-2.6#drm-modesetting. It still has the default_lock stuff, but hopefully that's not too hard to rip out. -- Jesse Barnes, Intel Open Source Technology Center |
