From: Mukul Joshi <[email protected]>
The recent overhauling of SDMA queue management introduced a
bug where XGMI SDMA user-mode queue allocation would mark bits
in the SDMA queue bitmap as set, representing a queue from
non-XGMI SDMA engines was allocated. This patch
addresses this issue and fixes the xGMI SDMA queue allocation.
Fixes: df7f2df1a466 ("drm/amdkfd: Update SDMA queue management for GFX9.4.3")
