From 0a34fad1bed45ff2245ab8c315bc3d4c6471af46 Mon Sep 17 00:00:00 2001 From: Chiara Meiohas Date: Wed, 26 Feb 2025 15:01:06 +0200 Subject: net/mlx5: Allow the throttle mechanism to be more dynamic Previously, throttle commands were identified and limited based on opcode. These commands were limited to half the command slots using a semaphore, and callback commands checked the opcode to determine semaphore release. To allow exceptions, we introduce a variable to indicate when the throttle lock is held. This allows scenarios where throttle commands are not limited. Callback functions use this variable to determine if the throttle semaphore needs to be released. This patch contains no functional changes. It's a preparation for the next patch.
