CDCLK is used to generate the gmbus clock. This is normally done by BIOS. Program the value if the BIOS-less system doesn't do it. v2: Move this to intel_i2c_reset to allow reprogram the gmbus frequency during resume. (Daniel) v3: Change GMBUS_FREQ to GMBUSFREQ_VLV, and use VLV_DISPLAY_BASE. (Ville). Remove cdclk_ratio[] table, and calculate the cdclk ratio instead. (Ville). Change the shift then mask for reg read, to mask first, then shift. (Ville). Remove the gmbus frequency calculation = cdclk/1.01. Based on BIOS programming, gmbus frequency = cdclk frequency. (Ville) Add get_disp_clk_div, which can use to get cdclk/czclk divide. v4: Fix the mmio_offset base for CZCLK_CDCLK_FREQ_RATIO, gmbus_freq calculation, and duplicate check for gmbus_freq. (Ville) In VLV, the spec is wrong about 4Mhz reference frequency for GMBUS. It should be 1Mhz. Signed-off-by:

Still digging up the actual VBT info for this, but wanted to get this out there for testing, or in case others are also bugged by this. This can happen if you boot with an external display connected. In that case, the attached eDP backlight modulation frequency may not be programmed, so we need to use something (in this case the value my BIOS normally programs with just the internal display enabled). v2: fix masking and magic value in read_blc_pwm_ctl (Jani) Signed-off-by:

Now that we ask to adjust the crtc timings for stereo modes, the correct pipe_src_w and pipe_src_h can be found in crtc_vdisplay and crtc_hdisplay. v2: Add comment about why pipe_src_w/h need to be set afert set_crtcinfo() (Daniel Vetter) Reviewed-by: -
Damien Lespiau authored
When scanning out big stereo buffers that are actually bigger that their natural 2D counterpart, we need to blow up the crtc timings as well. Not that this is only done for frame packing as this is the only stereo mode currently exposed needing this kind of ajdustements. Reviewed-by:

Damien Lespiau authored
struct drm_mode_display now has a separate crtc_ version of the clock to be used when we're talking about the timings given to the harwadre (was far as the mode is concerned). This commit is really the result of a git grep adjusted_mode.*clock and replacing those by adjusted_mode.crtc_clock. No functional change. v2: Rebased on drm-intel-queued-next Reviewed-by:

We want to dump the parameters given to the hardware, so let's use crtc_clock here. Reviewed-by:

Damien Lespiau authored
Some stereo modes, like frame packing, need a larger CRTC viewport than the "natural" underlying 2D mode and thus drm_crtc_check_viewport() needs to query the adjusted mode to use the correct h/vdisplay. Reviewed-by:

Damien Lespiau authored
Both setcrtc and page_flip are checking that the framebuffer is big enough for the defined crtc viewport (x, y, hdisplay, vdisplay). Factor that code out in a single function. Reviewed-by:

Damien Lespiau authored
When using the frame packing and a single big framebuffer, some hardware requires that we do everything like if we were scanning out the big buffer itself. Let's instrument drm_mode_set_crtcinfo() to be able to do this adjustement if the driver is asking for it. v2: Use crtc_vtotal and multiply the clock by 2 instead of reconstructing it (Ville Syrjälä) Suggested-by: -

When scanning out a stereo mode, the AVI infoframe vic field has to be the underlyng 2D VIC. Before that commit, we weren't matching the CEA mode because of the extra stereo flag and then were setting the VIC field in the AVI infoframe to 0. Reviewed-by:

When scanning out a 3D mode on HDMI, we need to send an HDMI infoframe with the corresponding layout to the sink. v2: Make s3d_structure_from_display_mode() less subtle (Ville Syrjälä) Reviewed-by:

When setting a stereo 3D mode, there can be only one bit set describing the layout of the frambuffer(s). So reject invalid modes early. Reviewed-by:

So we respect a nice design of having similar functions at the same level, in this case: do_hdmi_vsdb_modes() - add_hdmi_mandatory_stereo_modes() - add_hdmi_mode() Reviewed-by:

For now, let's just look at the 3D_present flag of the CEA HDMI vendor block to detect if the sink supports a small list of then mandatory 3D formats. See the HDMI 1.4a 3D extraction for detail: http://www.hdmi.org/manufacturer/specification.aspx v2: Rename freq to vrefresh, make the mandatory structure a bit more compact, fix some white space issues and add a couple of const (Ville Syrjälä) Reviewed-by:

This capability allows user space to control the delivery of modes with the 3D flags set. This is to not play games with current user space users not knowing anything about stereo 3D flags and that could try to set a mode with one or several of those bits set. So, the plan is to remove the stereo modes from the list of modes we give to DRM clients by default, and let them through if we are being told otherwise. stereo_allowed is bound to the drm_file structure to make it a per-client setting, not a global one. v2: Replace clearing 3D flags by discarding the stereo modes now that they are regular modes. v3: SET_CAP -> SET_CLIENT_CAP rename (Chris Wilson) Reviewed-by: -
Damien Lespiau authored
HDMI 1.4a defines a few layouts that we'd like to expose. This commits add new modeinfo flags that can be used to list the supported stereo layouts (when querying the list of modes) and to set a given stereo 3D mode (when setting a mode). v2: Add a drm_mode_is_stereo() helper Reviewed-by:

This ioctl can be used to turn some knobs in a DRM driver. The client can ask the DRM core for an alternate view of the reality: it can be useful to be able to instruct the core that the DRM client can handle new functionnality that would otherwise break current ABI. v2: Rename to ioctl from SET_CAP to SET_CLIENT_CAP (Chris Wilson) Reviewed-by:

It's a tiny bit more logical to find the different capabilities you can use with the GET_CAP ioctl next to the structure rather than putting them at the end of the file. v2: Tab align the litterals (David Herrmann) v3: Make it clearer that DRM_PRIME_CAP_EXPORT/IMPORT are flags of DRM_CAP_PRIME. v4: Rebase on top of latest bits (DRM_CAP_ASYNC_PAGE_FLIP was introduced) Reviewed-by: David Herrmann <dh.herrmann@gmail.com> (for v2) Signed-off-by: -

So that we can find the callers who introduce a ring stall. A single ring stall is not too unwelcome, the right issue becomes when they start to interlock and prevent any concurrent work. That, however, is a little tricker to detect with a mere tracepoint! v2: Rebrand it as a ring event, rather than an object event. v3: Include the seqno in the tracepoint for posterity or something.

Even though we track object activity and not VMA, because we have the active_list be based on the VM, it makes the most sense to use VMAs in the APIs. NOTE: Daniel intends to eventually rip out active/inactive LRUs, but for now, leave them be. v2: Remove leftover hunk from the previous patch which didn't keep i915_gem_object_move_to_active. That patch had to rely on the ring to get the dev instead of the obj. (Chris) Reviewed-by:

"We do fairly often lookup the ggtt vma for an obj." - Chris Wilson. As such, provide a function to offer slightly cheaper access to the vma. Not performance tested. By my quick estimation it saves at least 3 pointer dereferences from the existing mechanism.

Daniel complained that we keep adding stuff to the bottom of the file, so we constantly have conflicts. So reorganize everything and split them file-by-file, also sorting the files in alphabetical order. This way, patches touching different files will have a smaller chance of conflicting. Of course, this commit will conflict with everybody on the list :) Also remove a few useless comments and make some things fit into 80 lines. v2: - Conflict with intel_ddi_get_config Requested-by:
