From d5179020f5ce44fd449790a9c12ef6c1a90a2ca7 Mon Sep 17 00:00:00 2001 From: Mikko Perttunen Date: Thu, 19 Jan 2023 15:09:21 +0200 Subject: gpu: host1x: External timeout/cancellation for fences Currently all fences have a 30 second timeout to ensure they are cleaned up if the fence never completes otherwise. However, this one size fits all solution doesn't actually fit in every case, such as syncpoint waiting where we want to be able to have timeouts longer than 30 seconds. As such, we want to be able to give control over fence cancellation to the caller (and maybe eventually get rid of the internal timeout altogether). Here we add this cancellation mechanism by essentially adding a function for entering the timeout path by function call, and changing the syncpoint wait function to use it.
