Merge tag 'topic/drm-misc-2016-06-22-updated' of git://anongit.freedesktop.org/drm-intel into drm-next Again a pile of things all over - Conversion to rst from docbook from Jani. Looks real pretty, and the source is now actually readable (compared to horrible, horrible docbook xml)! https://01.org/linuxgraphics/gfx-docs/drm/ - device register/unregister rework from Chris, with follow-up work from Benjamin. Allows more drivers to demidlayer load/unload and others to remove a bit of boilerplate. - master/auth related cleanup, with docs - some dma-buf polish, merged by Sumit - small stuff all over (like build fixes from Arnd) Group maintainership seems to slowly take off, with both Thierry and Sumit pushing a few things.

- is_master can be removed, we can compute this by checking allowed_master (which really just tracks whether a master struct has been allocated for this fpriv in either open or set_master), and whether the fpriv is the current master on the device. - that frees up is_master as a good replacement name for allowed_master.

We already have a fallback in place to fill out the unique from dev->unique, which is set to something reasonable in drm_dev_alloc. Which means we only need to have a special set_busid for pci devices, to be able to care the backwards compat code for drm 1.1 around, which libdrm still needs. While developing and testing this patch things blew up in really interesting ways, and the code is rather confusing in naming things between the kernel code, ioctl #defines and libdrm. For the next brave dragon slayer, document all this madness properly in the userspace interface section of gpu.tmpl. v2: Make drm_dev_set_unique static and update kerneldoc. v3: Entire rewrite, plus document what's going on for posterity in the gpu docbook uapi section. v4: Drop accidental amdgpu hunk (Emil). v5: Drop accidental omapdrm vblank counter change (Emil). v6: Rebase on top of the sphinx conversion.

There can only be one current master, and it's for the overall device. Render/control minors don't support master-based auth at all. This simplifies the master logic a lot, at least in my eyes: All these additional pointer chases are just confusing. While doing the conversion I spotted some locking fail: - drm_lock/drm_auth check dev->master without holding the master_mutex. This is fallout from commit c996fd0b Author: Thomas Hellstrom <thellstrom@vmware.com> Date: Tue Feb 25 19:57:44 2014 +0100 drm: Protect the master management with a drm_device::master_mutex v3 but I honestly don't care one bit about those old legacy drivers using this. - debugfs name info should just grab master_mutex. - And the fbdev helper looked at it to figure out whether someone is using KMS. We just need a consistent value, so READ_ONCE. Aside: We should probably check if anyone has opened a control node too, but I guess current userspace doesn't really do that yet. v2: Balance locking, reported by Julia. v3: Rebase on top of Chris' oops fixes.

Make sti driver use register callback to move debugfs initialization out of sub-components creation. This will allow to convert driver .load() to drm_dev_alloc() and drm_dev_register(). sti_compositor bring up 2 crtc but only one debugfs init is needed so use drm_crtc_index to do it on the first one. This can't be done in sti_drv because only sti_compositor have access to the devices. It is almost the same for sti_encoder which handle multiple encoder while one only debugfs entry is needed so add a boolean to avoid multiple debugfs initialization Signed-off-by:

Pandoc really did a bad job of converting the big KMS properties table to RST. Instead, put the properties into a separate plain text CSV file, and include it in the RST file. The generated output isn't very pretty, but at least the information is there, and it's stored in a format that's easier to process and improve upon at a later time. The CSV file was generated by copy-pasting the table from the HTML generated by the DocBook toolchain into LibreOffice Calc, and then saved as CSV, unmodified. Signed-off-by:

While splitting the document up, the headings "shifted" from what pandoc generated. Use the following order for headings for consistency: ============== Document title ============== First ===== Second ------ Third ~~~~~ Leave the lower level headings as they are; I think those are less important. Although RST doesn't mandate a specific order ("Rather than imposing a fixed number and order of section title adornment styles, the order enforced will be the order as encountered."), having the higher levels the same overall makes it easier to follow the documents. [I'm sort of kind of writing the recommendation for docs-next in the mean time, but this order seems sensible, and is what I'm proposing.] Signed-off-by: -

This is the first step towards converting the DocBook gpu.tmpl to Sphinx and reStructuredText, the new kernel documentation tool and markup. Use Jon's "cheesy conversion script" in Documentation/sphinx/tmplcvt to do the rough conversion. Do the manual edits in follow-up patches. Add a new Documentation/gpu directories for the graphics related documentation. (Hooray, now we can have directories based on topics rather than tools under Documentation.) We also won't remove the DocBook gpu.tmpl yet so it's easier to build both and compare the results for parity. Signed-off-by:

Rockchip just blew up here on testing, because I removed some "is this crtc already disabled/enabled" state tracking from callbacks (not needed with atomic). Turns out that was needed to work around rockchip still calling legacy helper code. Since me explaining on irc/mailing-list plus kerneldoc isn't enough, be more verbose and add dmesg output.
