Subject: [PATCH 0/2] crypto: qat - GEN6 firmware loading fixes
Date: Thu,  5 Mar 2026 08:58:57 +0000	[thread overview]
Message-ID: <20260305085955.66293-1-suman.kumar.chakraborty@intel.com> (raw)

This small series addresses firmware loading reliability on QAT GEN6
devices.

The first patch fixes inconsistent whitespace in the macro definitions
in qat_hal.c, switching from mixed tabs and spaces to tabs throughout.

The second patch adds a hardware-required minimum 3 us delay during
the acceleration engine reset sequence for GEN6 devices. Without this
delay, firmware loading may fail intermittently. Earlier generations
are unaffected.
