4514994

Description: Fixed performance degradation on older kernel versions using RX cache, particularly on slower ARM CPUs with larger RX buffers. The issue was caused by the driver attempting to allocate new RX pages too quickly, leading to head-of-line blocking in the RX cache. The fix improves RX cache usage by triggering page allocation for a bulk of at least 2 WQEs, allowing the application more time to process packets and return buffers to the RX cache, thereby reducing blocking and enhancing performance.

Keyword: Performance, kernel, Rx cache, page allocation

Detected in version: 3.0.0

4945554

Description: If a secondary BMC task (such as a log dump) is started after the BMC firmware update has been initiated, but before the installer's monitoring logic has attached to it, the installer may mistakenly track the secondary task. This tracking error causes the installer to misjudge the update's completion, which can cause the subsequent BMC reboot to fail and leave the new firmware in a pending, unactivated state.

Reported in version: 26.01

4401488

Description: The BMC kernel enforces CONFIG_STATIC_USERMODEHELPER, which routes all usermode helper calls to /sbin/usermode-helper. Because this executable does not exist on the system, these calls fail and may cause undefined system behavior.

Reported in version: 26.01

4905017

Description: When operating in NIC mode, a host power cycle may intermittently cause the UEFI to fail to retrieve BMC Redfish credentials. This results in a DPU-BMC RF credentials not found error and introduces a timeout delay during the boot sequence.

Reported in version: 26.01
