drm/doc: Clarify what ioctls can be used on render nodes

2022-03-17T09:37:08+00:00

The documentation for render nodes indicates that only "PRIME-related" ioctls are valid on render nodes, but the documentation does not clarify what that means. If the reader is not familiar with PRIME, they may beleive this to be only the ioctls with "PRIME" in the name and not other ioctls such as set of syncobj ioctls. Clarify the situation for the reader by referencing where the reader will find a current list of valid ioctls.

drm: clarify usage of drm leases

2021-07-29T07:12:01+00:00

We make the following changes to the documentation of drm leases to make it easier to reason about their usage. In particular, we clarify the lifetime and locking rules of lease fields in drm_master: 1. Make it clear that &drm_device.mode_config.idr_mutex protects the lease idr and list structures for drm_master. The lessor field itself doesn't need to be protected as it doesn't change after it's set in drm_lease_create. 2. Add descriptions for the lifetime of lessors and leases. 3. Add an overview DOC: section in drm-uapi.rst that defines the terminology for drm leasing, and explains how leases work and why they're used.

drm/doc: document how userspace should find out CRTC index

2021-06-10T17:14:47+00:00

In this patch we add a section to document what userspace should do to find out the CRTC index. This is important as they may be many places in the documentation that need this, so it's better to just point to this section and avoid repetition.

drm/doc: render drm.h uapi docs

2021-01-05T13:22:26+00:00

It doesn't seem like drm.h docs are included anywhere. Render them next to drm_mode.h, under the "Userspace API Structures" section. This also allows references to e.g. DRM_CAP_* to be properly linkified elsewhere in our docs.

drm/doc: Add VKMS module description and use to "Testing and Validation"

2019-12-05T23:52:12+00:00

Add a description on VKMS module and the cases in which it should be used. There's a brief explanation on how to set it and use it in a VM, along with an example of running an igt-test. Changes since V3: Rodrigo: - Change the log message to imperative - Fix some bad spelling/writing - Add a blank line before enumeration Changes since V2: Andre: - Avoid repetition of words in the same sentence; - Make the explanation on 'setting the kernel' shorter, eliminate the 'make menuconfig' command; - Add tab on enumeration to have one line per item; - Clarify from each machine igt-tests commands should be ran on.

drm/doc: Update IGT documentation

2019-11-04T18:06:08+00:00

The IGT documentation in this page is telling us to build it using make. According to commit 67993c1 ("automake: Point builders at meson") from the IGT project, this is deprecated and IGT should be built with meson. Instead of having a documentation for IGT in this page, point to their GitLab README, which should always be up to date.
