9 years agomodetest: initialize handles/pitches in set_plane()

modetest: initialize handles/pitches in set_plane()

Only the 'offsets' array was initialized to zero.
Since bo_create only sets the handles which are
necessary, were we passing garbage data to the
kernel when calling drmModeAddFB2 later.

The issue only seems to appear when passing e.g.
NV12 data to the kernel, a case where not only
handles[0] is used. I therefore also removed the
corresponding comment.

v2: Do the same for set_mode(), set_cursors()
    and test_page_flip().

Update kernel interface with new I915_GETPARAM ioctl entries for
subslice total and EU total. Add a wrapping function for each
parameter. Userspace drivers need these values when constructing
GPGPU commands. This kernel query method is intended to replace
the PCI ID-based tables that userspace drivers currently maintain.
The kernel driver can employ fuse register reads as needed to
ensure the most accurate determination of GT config attributes.
This first became important with Cherryview in which the config
could differ between devices with the same PCI ID.

The kernel detection of these values is device-specific. Userspace
drivers should continue to maintain ID-based tables for older
devices which return ENODEV when using this query.

9 years agodrm: add drmGet(Primary|Render)DeviceNameFromFd functions
Emil Velikov [Sat, 7 Mar 2015 00:58:39 +0000 (00:58 +0000)]
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.
