From 0da5698bf4b8c699e5e5e23d067f5a1bb1bb2401 Mon Sep 17 00:00:00 2001 From: Oded Gabbay Date: Tue, 27 Oct 2020 09:34:44 +0200 Subject: [PATCH] habanalabs/gaudi: increase MAX CS to 16K We need to have the MAX CS be much larger than the size of the different queues. In GAUDI we have around 8 groups of queues, and each group has 1K queue size. To prevent head-of-the-line blocking, we need to make sure there is sufficient number of available CS allocations even if one or more of those queues are full.
