I wondered about that in the places I copied my code from. Good to know
there's a better practice. I've switched to using this form.

I switched all of the inappropriate usage to this form for six separate
patches (three each for core/anv/radv by two extensions (DISPLAY and 
XLIB_XRANDR).

Awesome!

Thanks for reviewing the build system bits; I'm just starting to use
meson and every new change is a learning opportunity at this point.

Can be simplified a bit:

  _xlib_lease = get_option('xlib-lease')
  if _xlib_lease == 'auto'
with_xlib_lease = with_platform_x11 and with_platform_display
  else
with_xlib_lease = _xlib_lease == 'true'
  endif

(We also usually try to avoid changing the type of a var, and meson might
start being more strict with types in future releases)

[PATCH 07/21] vulkan: Add EXT_acquire_xlib_display

2018-02-13 Thread Keith Packard 
This extension adds the ability to borrow an X RandR output for
temporary use directly by a Vulkan application. For DRM, we use the
Linux resource leasing mechanism.
