The switch manager writes to this\nregister to clear mailbox global interrupt bits as part of its mailbox\ninterrupt handling routine. When the device recovers from the data path\nreset and these bits are not cleared, it will prevent future mailbox\nglobal interrupts from being triggered. Upon confirming that the device\nhas exited from a data path reset, clear these bits to ensure the proper\nfunctioning of the mailbox global interrupt.\n\nSigned-off-by: Ngai-Mint Kwan <ngai-mint.kwan@intel.com>\nSigned-off-by: Jacob Keller <jacob.e.keller@intel.com>\n---\n drivers/net/ethernet/intel/fm10k/fm10k_mbx.h | 2 ++\n drivers/net/ethernet/intel/fm10k/fm10k_pf.c | 4 ++++\n 2 files changed, 6 insertions(+)", "diff": "diff --git a/drivers/net/ethernet/intel/fm10k/fm10k_mbx.h b/drivers/net/ethernet/intel/fm10k/fm10k_mbx.h\nindex b7dbc8a84c05..35c1dbad1330 100644\n--- a/drivers/net/ethernet/intel/fm10k/fm10k_mbx.h\n+++ b/drivers/net/ethernet/intel/fm10k/fm10k_mbx.h\n@@ -41,6 +41,8 @@ struct fm10k_mbx_info;\n #define FM10K_MBX_ACK_INTERRUPT\t\t\t0x00000010\n #define FM10K_MBX_INTERRUPT_ENABLE\t\t0x00000020\n #define FM10K_MBX_INTERRUPT_DISABLE\t\t0x00000040\n+#define FM10K_MBX_GLOBAL_REQ_INTERRUPT\t\t0x00000200\n+#define FM10K_MBX_GLOBAL_ACK_INTERRUPT\t\t0x00000400\n #define FM10K_MBICR(_n)\t\t((_n) + 0x18840)\n #define FM10K_GMBX\t\t0x18842\n \ndiff --git a/drivers/net/ethernet/intel/fm10k/fm10k_pf.c b/drivers/net/ethernet/intel/fm10k/fm10k_pf.c\nindex dc75507c9926..69e2c822db00 100644\n--- a/drivers/net/ethernet/intel/fm10k/fm10k_pf.c\n+++ b/drivers/net/ethernet/intel/fm10k/fm10k_pf.c\n@@ -77,6 +77,10 @@ static s32 fm10k_reset_hw_pf(struct fm10k_hw *hw)\n \tif (!(reg & FM10K_IP_NOTINRESET))\n \t\terr = FM10K_ERR_RESET_FAILED;\n \n+\t/* Reset mailbox global interrupts */\n+\treg = FM10K_MBX_GLOBAL_REQ_INTERRUPT | FM10K_MBX_GLOBAL_ACK_INTERRUPT;\n+\tfm10k_write_reg(hw, FM10K_GMBX, reg);\n+\n out:\n \treturn err;\n }\n", "prefixes": [ "v2", "02/18" ] }
