pfcwd: fix TypeError crash in interval() on partial PFC_WD entries |
PFC Watchdog CLI — pfcwd/main.py · sonic-net/sonic-utilities |
🔄 Open — DCO ✅ · EasyCLA ✅ · PR #4541 |
pfc_stat_history_cmd creates partial PFC_WD entries with no detection_time/restoration_time. interval() called int(None) unconditionally, crashing and permanently blocking polling-interval updates. Fix guards before conversion, skips incomplete entries, and consolidates redundant DB reads. Includes regression test.
DPDK is the high-performance packet-processing framework used in data centers, 5G, and networking infrastructure — same git send-email workflow as the Linux kernel.

NXP DPAA2 DMA driver — drivers/dma/dpaa2/dpaa2_qdma.c |
🔄 Under review — dev@dpdk.org · CC: Gagandeep Singh, Hemant Agrawal (NXP) |
fslmc_bus_unplug() discarded drv->remove() return value, always reporting success. dpaa2_qdma_remove() logged errors but returned 0, hiding failures from callers. Fixes Bugzilla #1914. Both patches tagged Cc: stable@dpdk.org.
U-Boot is the bootloader used in embedded Linux systems including NXP i.MX6Q-based medical devices (patient monitors, ultrasound, imaging).

SPL overflow fix for clk: imx6q patch series |
drivers/clk/imx/clk-imx6q.c — guard of_assigned_ldb_sels() and imx6q_init_ldb_clks() with !CONFIG_SPL_BUILD |
🔄 Sent to maintainer — fix for CI failure reported by Fabio Estevam · CC: Brian Ruley (GE Healthcare) |
Diagnosed and fixed an SPL SRAM overflow (112 bytes) caused by LDB display clock initialisation code being pulled into SPL via imx6q_clk_probe(). SPL never initialises a display — guarding the two functions reduces SPL text by ~688 bytes and unblocks the patch series.
