This is a bitmask, mirroring cardRequiredCapabilityBitmask, where each set bit indicates a hardware capability this card's actual physical hardware supports, regardless of what the current configuration requires. Comparing this against cardRequiredCapabilityBitmask is the direct way an admin checks for a capability shortfall: any bit set in the required mask but clear in this operational mask means a configured feature is relying on a hardware capability this specific card doesn't actually support, likely causing that feature to silently fail or degrade. For example, the required mask showing the vp-shaping(4) bit set while the operational mask lacks it reveals that VP shaping was configured but this card's hardware can't actually deliver it.
