Subject: [PATCH 2/3] drm/xe/guc/ct: Increase wait timeout for g2h response
Date: Wed,  9 Oct 2024 16:26:44 +0530	[thread overview]
Message-ID: <20241009105645.1416588-3-badal.nilawar@intel.com> (raw)
In-Reply-To: <20241009105645.1416588-1-badal.nilawar@intel.com>

Occasionally, the G2H worker starts running after a delay of more than
a second even after being queued and activated by the Linux workqueue
subsystem.
To prevent G2H timeout errors, the wait timeout is being increased.
