Jonas Karlman de88f74df9 modetest: add support for DRM_FORMAT_NV{15,20,30}
Add smpte and tiles pattern for 10-bit NV15, NV20 and NV30 pixel formats
based on the existing pattern for NV12 with colors simply scaled from
8-bit to 10-bit.

These pixel formats are typically used by video decoder and display
pipeline on Rockchip SoCs, e.g. on RK322X, RK3288, RK3328 and RK3399
the video decoder produce 10-bit video frames in NV15 and NV20 format.

NV20 and NV30 pixel formats was added in drm-misc commit 728c15b4b5f3
("drm/fourcc: Add NV20 and NV30 YUV formats").

This can be tested/validated on Rockchip SoCs with drm-misc commit
d4b384228562 ("drm/rockchip: vop: Add NV15, NV20 and NV30 support").

Geert Uytterhoeven a2dbfd6442 modetest: add SMPTE pattern support for C[124] formats
Add support for drawing the SMPTE pattern in buffers using a
color-indexed frame buffer formats with two, four, or sixteen colors.

Note that this still uses 256 as the CLUT size, as
DRM_IOCTL_MODE_SETGAMMA enforces that the size matches against the
(fixed) gamma size, while the CLUT size depends on the format.

Move clearing the color LUT entries from util_smpte_index_gamma() to its
caller, as only the caller knows how many entries there really are
(currently DRM always assumes 256 entries).

 *
 * Set the gamma table of a CRTC to the one passed in by the user. Userspace can
 * inquire the required gamma table size through drm_mode_gamma_get_ioctl.

 * drm_mode_gamma_get_ioctl - get the gamma table
 *
 * Copy the current gamma table into the storage provided. This also provides
 * the gamma table size the driver expects, which can be used to size the
 * allocated storage.

but the code doesn't seem to support that in an easy way (like setting
red/green/blue to NULL on input, retrieving gamma_size on output), only
by providing big enough buffers for red/green/blue, and looping over
gamma_size until -EINVAL is no longer returned.

Geert Uytterhoeven 6d9645bb3b util: factor out and optimize C8 SMPTE color LUT
The color LUT for the SMPTE pattern in indexed mode contains 22 entries,
although only 13 are non-unique.

Reduce the size of the color LUT by dropping duplicate entries, so it
can be reused for formats supporting e.g. 16 colors.  Rename the
function util_smpte_c8_gamma() to util_smpte_fill_lut(), and its first

Marijn Suijten dfd00c6250 modetest: allocate and commit atomic request around set_property()
Currently the atomic request is only assigned after `set_property()` is
called, leaving `dev.req` in its uninitialized state causing
`drmModeAtomicAddProperty()` to return an error code, which is printed
as `"Success"` because `errno` is not set by `libdrm` (but it would have
been when non-atomic `drmModeObjectSetProperty()` called an IOCTL
immediately):

    sony-akatsuki-row ~ $ modetest -M msm -a -w 81:ACTIVE:0
    failed to set CRTC 81 property ACTIVE to 0: Success

Solve this by assigning a new atomic request object before calling
`set_property()`, when there are properties to set.  Likewise, commit
these properties after `set_property()` even if there is no other
operation (setting modes or planes) specified.

Furthermore `drmModeObjectSetProperty()` is implemented in terms of
`DRM_IOCTL()` which already returns `-errno` when `ioctl()` returns
`-1`, so we should instead pass `ret` to `strerror()` and get an
accurate error string out of `drmModeAtomicAddProperty()` too.

Marijn Suijten 64b09cef49 modetest: document why no blob is created for linear gamma LUT
As found and discussed in [MR 58] a blob is not created in the else arm
because adding the GAMMA_LUT property with a NULL/0 blob_id causes it
to be reset to a default linear / pass-thru gamma table.  The values
in the gamma_lut table might still be consumed in the legacy API path
below though, so it has to be initialized to a linear table.

Eleni Maria Stea 4caec56fb8 modeprint, modetest, proptest: cast __u64 to uint64_t
It seems that __u64 values are defined differently across systems. In
glibc it's defined as unsigned long, in Linux kernel headers
(int-ll64.h) as unsigned long long, and on FreeBSD as uint64_t so it
matches glibc. A temporal solution is to cast all __u64 values to
uint64_t to avoid warnings on Linux, but ideally we'd like a better fix
in the future.

Marius Vlad 67e911977f xf86drm: Add a human readable representation for format modifiers
Introduces two new methods to retrieve a human readable representation of a
format modifier:

drmGetFormatModifierName() - returns a format modifier as a string,
from a token modifier
drmGetFormatModifierVendor() - returns the vendor as a string, from a
token modifier

and the fourcc_mod_get_vendor macro that returns the vendor.

New format modifiers added in drm_fourcc.h uapi kernel header should be
sync'ed up with libdrm and should include a human readable
representation for that format modifier, in order to display it
correctly as a string.

That happens with the help of a python script that reads up drm_fourcc
header file and outputs a static table comprised of token modifiers
alongside a vendor table (Suggested-by Simon Ser <contact@emersion.fr>).

The reason for doing it in libdrm is to have a unified place instead of each
user of libdrm having a way to keep track of the format modifiers.

With this patch, modetest has also been modified to make use of it.

select more appropriate mode using suitable refresh rate value.

V4:
1) While setting mode, print mode name and vrefresh using struct
   drmModeModeInfo instead of struct pipe_args.
2) Revert back to using a float value instead of float *
   for vrefresh arg in connector_find_mode().

V3:
1) Change name of function used to derive refresh rate.

V2:
1) Don't use inline function for deriving refresh rate from mode.
2) If requested mode not found, print refresh rate only
   if user had provided it in args.

Devarsh Thakkar a2d588fe12 modetest: Add support for setting mode having floating vertical refresh rate
For the scenario where user may require to modeset with a mode
supporting a fractional value for vertical refresh-rate,
appropriate mode can be selected by searching for mode
having matching fractional vertical refresh rate using
below equation.

vrefresh = (1000 * pixel clock) / (htotal * vtotal) Hz.

We do this way since driver doesn't return float value of vrefresh
as it use int for vrefresh in struct drm_mode_info, but we can derive
the actual value using pixel clock, horizontal total size and
vertical total size values.

So for e.g. if user want to select mode having 59.94 Hz as refresh rate
then with this patch it be can done as shown in below command,
given there is an appropriate mode is available :

modetest -M xlnx -s 39:1920x1080-59.94@BG24 -v

NOTE: Above command was tested on xilinx DRM driver with DP
monitor which was supporting mode having 59.94 Hz refresh rate.

V2: Update commit message
V3: Update with below changes as per review comments :
  1) Use epsilon for vrefresh comparison
  2) Use implicit type-casting wherever possible
V4: Keep patch version history on main commit message
