Subject: [Intel-gfx] [PATCH] drm/i915/bios: Fix ports mask
Date: Wed, 21 Jul 2021 18:00:23 -0400 [thread overview]
Message-ID: <20210721220023.268194-1-rodrigo.vivi@intel.com> (raw)
PORT_A to PORT_F are regular integers defined in the enum port,
while for_each_port_masked requires a bit mask for the ports.
Current given mask: 0b111
Desired mask: 0b111111
I noticed this while Christoph was reporting a bug found on headless
GVT configuration which bisect blamed commit 3ae04c0c7e63 ("drm/i915/bios:
limit default outputs to ports A through F")
