From 427be1b4debef20f97f56c7dd0659fd0b8b33313 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Thu, 30 May 2024 17:26:29 +0200 Subject: [PATCH] mmc: sdhci-of-dwcmshc: set CQE irq-handler for rockchip variants The dwcmshc used on Rockchip rk3568 and rk3588 can use cqe, so set the needed irq handler. Tested on a rk3588-tiger SoM with dd, hdparm and fio. fio performance does increase slightly from Run status group 0 (all jobs): READ: bw=209MiB/s (219MB/s), 209MiB/s-209MiB/s (219MB/s-219MB/s), io=4096MiB (4295MB), run=19607-19607msec without CQE to Run status group 0 (all jobs): READ: bw=215MiB/s (225MB/s), 215MiB/s-215MiB/s (225MB/s-225MB/s), io=4096MiB (4295MB), run=19062-19062msec with CQE enabled.
