2015-12-09drm/i915: constify intel_dvo_dev_ops structuresJulia Lawall1-1/+1
The intel_dvo_dev_ops structures are never modified, so declare them as const. Done with the help of Coccinelle.

2015-09-30drm/i915: Constify adjusted_modeVille Syrjälä1-2/+2
Make adjusted_mode const whereever we don't have to modify it. This only covers cases when we have a local adjusted_mode variable, and doesn't make any difference for cases where we just dereference pipe_config->adjusted_mode.

2014-03-28drm/i915: Replace DRM_LOG_KMS() by DRM_DEBUG_KMS()Lespiau, Damien1-5/+5
There are only a few users of the DRM_LOG_KMS() macro. We can simplify the DRM code a bit by replacing them by DRM_DEBUG_KMS(). Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2012-09-06drm/i915/dvo: implement get_hw_stateDaniel Vetter1-0/+16
Similar to the sdvo code we poke the dvo encoder whether the output is active. Safe that dvo encoders are not standardized, so this requires a new callback into the dvo chip driver. Hence implement that for all 6 dvo drivers. v2: With the newly added ns2501 we now have 6 dvo drivers instead of just 5 ...

2012-08-17drm/i915: simplify dvo dpms interfaceDaniel Vetter1-2/+2
All dvo drivers only support 2 dpms states, and our dvo driver even switches of the dvo port for anything else than DPMS_ON. Hence ditch this complexity and simply use bool enable. While reading through this code I've noticed that the mode_set function of ch7017 is a bit peculiar - it disable the lvds again, even though the crtc helper code should have done that ... This might be to work around an issue at driver load, we pretty much ignore the hw state when taking over. v2: Also do the conversion for the new ns2501 driver.

2010-09-18drm/i915: use GMBUS to manage i2c linksChris Wilson1-6/+4
Use the GMBUS interface rather than direct bit banging to grab the EDID over DDC (and for other forms of auxiliary communication with external display controllers). The hope is that this method will be much faster and more reliable than bit banging for fetching EDIDs from buggy monitors or through switches, though we still preserve the bit banging as a fallback in case GMBUS fails. Based on an original patch by Jesse Barnes. Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-04-12drm/i915: Remove dead KMS encoder save/restore code.Eric Anholt1-38/+0
This was brought over from UMS, and used for a while until we decided that drm_helper_resume_force_mode was easier and more reliable, since it didn't require duplicating all the code deleted here. We just forgot to delete all that junk for a while.

2009-06-19drm/i915: Change I2C api to pass around i2c_adaptersKeith Packard1-12/+13
The existing API passed around intel_i2c_chan pointers, which are dependent on the i2c bit-banging algo. This precluded the driver from using outputs which use a different algo. Switching to the more general i2c_adpater allows the driver to support non bit-banging DDC. This also required moving the slave address into the output private structures.

2008-12-29DRM: i915: add mode setting supportJesse Barnes1-0/+302
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.
