static void hbg_debugfs_uninit(void *data)
the driver requested three interrupts: "tx", "rx", "err". The err interrupt is a summary interrupt. We distinguish different errors based on the status register and mask. With "cat /proc/interrupts | grep hibmcge", we can't distinguish the detailed cause of the error, so we added this file to debugfs. the following effects are achieved: [root@localhost sjj]# cat /sys/kernel/debug/hibmcge/0000\:83\:00.1/irq_info RX : enabled: true , logged: false, count: 0 TX : enabled: true , logged: false, count: 0 MAC_MII_FIFO_ERR : enabled: false, logged: true , count: 0 MAC_PCS_RX_FIFO_ERR : enabled: false, logged: true , count: 0 MAC_PCS_TX_FIFO_ERR : enabled: false, logged: true , count: 0 MAC_APP_RX_FIFO_ERR : enabled: false, logged: true , count: 0 MAC_APP_TX_FIFO_ERR : enabled: false, logged: true , count: 0 SRAM_PARITY_ERR : enabled: true , logged: true , count: 0 TX_AHB_ERR : enabled: true , logged: true , count: 0 RX_BUF_AVL : enabled: true , logged: false, count: 0 REL_BUF_ERR : enabled: true , logged: true , count: 0 TXCFG_AVL : enabled: true , logged: false, count: 0 TX_DROP : enabled: true , logged: false, count: 0 RX_DROP : enabled: true , logged: false, count: 0 RX_AHB_ERR : enabled: true , logged: true , count: 0 MAC_FIFO_ERR : enabled: true , logged: false, count: 0 RBREQ_ERR : enabled: true , logged: false, count: 0 WE_ERR : enabled: true , logged: false, count: 0 The irq framework of hibmcge driver also includes tx/rx interrupts. Therefore, TX and RX are not moved separately form this file.
