Gurchetan Singh 5226b52773 xf86drm: continue after drmProcessPlatformDevice failure
On ChromeOS devices, readdir() processes the directory in
the following order:

-NAME-              -TYPE-
.                    n/a
..                   n/a
vgem                 n/a

card0             DRM_BUS_PCI
renderD128        DRM_BUS_PCI
controlD64        DRM_BUS_PCI

In drmGetDevices2, after drmProcessPlatformDevice fails for
/dev/dri/card1, we don't process the remaining directory entries.
As such, Vulkan fails to initialize since Mesa uses drmGetDevices2.
To fix this, continue if drmProcessPlatformDevice fails.

Adam Jackson 7c27cd7c5d Export drmDevicesEqual
drmCompareBusInfo was almost this already, but it wasn't exported, its
name didn't match its functionality, and while it almost looks like it
was usable for sorting due to memcmp it wouldn't work if you had
multiple bus types. I don't really want to think about defining a
sensible sort order for bus types, so let's at least make it less of a
trap for the caller.

Invert its boolean sense to be 'true if equal', rename it to describe
the types it actually operates on, and export.

Thierry Reding 5403cb39c1 xf86drm: Reuse sysfs_uevent_get()
Recent patches for USB, platform and host1x bus support introduced the
sysfs_uevent_get() function that provides a generic way of parsing the
sysfs uevent file that is associated with each device in Linux.

Open-coded variants of this still exist in other places, so make those
reuse the new function to remove some code duplication.

Thierry Reding 7b1f37f474 xf86drm: Add platform and host1x bus support
ARM SoCs usually have their DRM/KMS devices on the platform bus, so add
support for that to enable these devices to be used with the drmDevice
infrastructure.

NVIDIA Tegra SoCs have an additional level in the hierarchy and DRM/KMS

platform bus.

v4:
- continue on error to process platform or host1x device

v3:
- guard Linux-specific sysfs parsing code with #ifdef __linux__

v2:
- be careful not to overflow the full name

returned an error for any node the function would return an error,
ignoring any valid nodes.

The result of this on OpenBSD where drmProcessPciDevice() results in
device nodes being opened to issue ioctls to get pci data
was that data obtained from /dev/drm0 would be ignored if /dev/drm1
could not be opened.

Emil Velikov 11687bf418 xf86drm: introduce drmGetDevice[s]2
Relative to the original version, here one can provide a flags bitmask.
Currently only DRM_DEVICE_IGNORE_PCI_REVISION is supported.

Implementation detail:
If it's set, we will only parse the separate sysfs files and we won't
touch the config one. The latter awakes the device (causing delays)
which is the core reason why this API was introduced.

v2:
 - Initialize revision to 0xff if it's unread.
 - Change DRM_DEVICE_IGNORE_PCI_REVISION to DRM_DEVICE_GET_PCI_REVISION
 - Add explicit note that drmGetDevice[s]2 does not retrieve the
revision by default.

v3:
 - Correctly fold drmParsePciDeviceInfo() hunk in this patch.

Emil Velikov aae3f318d5 xf86drm: parse the separate sysfs files for vendor... info
Up-to recently (patch should land in 4.10) the kernel did not expose the
PCI device revision field as a separate sysfs file.

Thus one needed too parse the config file to retrieve it. This in
itself wakes up the device, which in some cases can be quite slow.

To avoid that, just check for the separate files and fall-back to the
original if kernel is not new enough.

Matt Roper 8c4a1cbd98 xf86drm: Fix error handling for drmGetDevices()
If the opendir() call in drmGetDevices() returns failure, we jump to an
error label that calls closedir() and then returns.  However this means
that we're calling closedir(NULL) which may not be safe on all
implementations.  We are also leaking the local_devices array that was
allocated before the opendir() call.

Fix both of these issues by jumping to an earlier error label (to free
local_devices) and guarding the closedir() call with a NULL test.

Similar interface to the *Devices() ones but they obtain/free the

Note there is a fair bit of duplication between the two Get functions,

Emil Velikov 5f68d31820 xf86drm: rework drmGetDevices()
Do a once off memory allocation for each drmDevice.

This allows us to ease the error handling and simplify the
de-duplication loop. As part of this we need to rework drmFreeDevice()
such so that it frees the relevant hunks, rather than leaving that to
the caller.

Some memory stats from the drmdevice test

before: 22 allocs, 22 frees, 66,922 bytes allocated
after:   9 allocs, 9 frees, 66,436 bytes allocated

Emil Velikov b556ea127e drm: add interface to get drm devices on the system v3
For mutiple GPU support, the devices on the system should be enumerated
to get necessary information about each device, and the drmGetDevices
interface is added for this. Currently only PCI devices are supported for
the enumeration.

Typical usage:
int count;
drmDevicePtr *foo;
count = drmGetDevices(NULL, 0);
foo = calloc(count, sizeof(drmDevicePtr));
count = drmGetDevices(foo, count);
/* find proper device, open correct device node, etc */
drmFreeDevices(foo, count);
free(foo);

v2: [Jammy Zhou]

v3: [Jammy Zhou]

Steam('s runtime).

Let's revert this for now and add a tweaked API later on that can be

Emil Velikov 0ca03a4087 drm: add drmGet(Primary|Render)DeviceNameFromFd functions
Currently most places assume reliable primary(master) <> render node
mapping. Although this may work in some cases, it is not correct.

Add a couple of helpers that hide the details and provide the name of
the master or render device name, given an fd. The latter may belong to
either the master, control or render node device.

v2:
 - Rename Device and Primary to Master (aka the /dev/dri/cardX device).
 - Check for the file via readdir_r() rather than stat().
 - Wrap the check into a single function.
 - Return NULL for non-linux platforms.

v3:
 - Don't segfault if name is NULL.
 - Update function names, as suggested by Frank Binns.

v4:
 - Update commit message to reflect the function name changes.

All the other offenders (tests, freedreno/kgsl, ...) don't really
matter (e.g. kgsl is the blob library and so not a drm thing) or are
again special exceptions with their own retry loops.
