Add function to derive floating value of vertical refresh rate from drm mode using pixel clock, horizontal total size and vertical total size. Use this function to find suitable mode having vrefresh value which is matching with user provided vrefresh value. If user doesn't provide any vrefresh value in args then update vertical refresh rate value in pipe args using this function. Also use this function for printing floating vrefresh while dumping all available modes. This will give more accurate picture to user for available modes differentiated by floating vertical refresh rate and help user 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.

libdrm - userspace library for drm
----------------------------------
This is libdrm, a userspace library for accessing the DRM, direct rendering
manager, on Linux, BSD and other operating systems that support the ioctl
interface.
The library provides wrapper functions for the ioctls to avoid exposing the
kernel interface directly, and for chipsets with drm memory manager, support
for tracking relocations and buffers.
New functionality in the kernel DRM drivers typically requires a new libdrm,
but a new libdrm will always work with an older kernel.
libdrm is a low-level library, typically used by graphics drivers such as
the Mesa drivers, the X drivers, libva and similar projects.
Compiling
---------
To set up meson:
meson builddir/
By default this will install into /usr/local, you can change your prefix
with --prefix=/usr (or `meson configure builddir/ -Dprefix=/usr` after
the initial meson setup).
Then use ninja to build and install:
ninja -C builddir/ install
If you are installing into a system location you will need to run install
separately, and as root.
