Subject: [PATCH] drm/xe/xe3p_xpc: Add new XeCore fuse registers to VF runtime regs
Date: Tue, 10 Feb 2026 10:25:19 -0800 [thread overview]
Message-ID: <20260210182519.206952-2-matthew.d.roper@intel.com> (raw)
SRIOV VFs do not automatically have access to the XeCore fuse registers.
Add the two new registers that show up on Xe3p_XPC to the runtime
register list to grant VFs access. Since there's a single runtime
register list for all Xe3p, this will technically also grant access on
Xe3p_LPG platforms where the registers don't exist, but that should be
harmless since even if a VF tries to read a non-existent register on
those platforms it will just get back a sensible value of 0x0.
Fixes: e8100643ff01 ("drm/xe/xe3p_xpc: XeCore mask spans four registers")
