Subject: [PATCH 1/3] drm/xe: Allow vram bo allocations aligned to 64K
Date: Tue, 13 Feb 2024 22:24:16 +0100	[thread overview]
Message-ID: <20240213212418.1309-2-michal.wajdeczko@intel.com> (raw)
In-Reply-To: <20240213212418.1309-1-michal.wajdeczko@intel.com>

While today we are getting vram allocations aligned to 64K as the
XE_VRAM_FLAGS_NEED64K flag could be set, we shouldn't only rely on
that flag and we should also allow caller to specify required 64K
alignment explicitly.  Define new XE_BO_NEEDS_64K flag for that.
