This works only if the TQMAP/RQMAP registers are set to map\nall of the out-of-bound rings back to the first one. This allows the VF\nto cleanly detect when it has run out of queues. Update the PF code so\nthat it resets the empty TQMAP/RQMAP registers post-VFLR to prevent\ninnocent VF drivers from triggering malicious driver events.\n\n-rc3\n* Use corrected index, instead of 1\n\nSigned-off-by: Matthew Vick <matthew.vick@intel.com>\nSigned-off-by: Jacob Keller <jacob.e.keller@intel.com>\n---\n drivers/net/ethernet/intel/fm10k/fm10k_pf.c | 6 ++++++\n 1 file changed, 6 insertions(+)", "diff": "diff --git a/drivers/net/ethernet/intel/fm10k/fm10k_pf.c b/drivers/net/ethernet/intel/fm10k/fm10k_pf.c\nindex 891e21874b2a..49c8ad647680 100644\n--- a/drivers/net/ethernet/intel/fm10k/fm10k_pf.c\n+++ b/drivers/net/ethernet/intel/fm10k/fm10k_pf.c\n@@ -1046,6 +1046,12 @@ static s32 fm10k_iov_reset_resources_pf(struct fm10k_hw *hw,\n \t\tfm10k_write_reg(hw, FM10K_RQMAP(qmap_idx + i), vf_q_idx + i);\n \t}\n \n+\t/* repeat the first ring for all the remaining VF rings */\n+\tfor (i = queues_per_pool; i < qmap_stride; i++) {\n+\t\tfm10k_write_reg(hw, FM10K_TQMAP(qmap_idx + i), vf_q_idx);\n+\t\tfm10k_write_reg(hw, FM10K_RQMAP(qmap_idx + i), vf_q_idx);\n+\t}\n+\n \treturn 0;\n }\n \n", "prefixes": [ "rc3" ] }
