This causes issue in their usages in\nshared uses in case of multi-process applications. It can overcome by using\nallowlist/blocklist in primary and secondary applications.\nHowever it imposes restrictions on standard debugging apps like\ndpdk-procinfo, which can be used to debug any existing application.\n\nThis patch introduces reserving extra DPMCP and DPIO to be used by\nsecondary process if devices are not blocked previously in primary\napplication.\nThis leaves the last DPMCP and DPIO for the secondary process usages.\n\nSigned-off-by: Rohit Raj <rohit.raj@nxp.com>\nReviewed-by: Sachin Saxena <sachin.saxena@oss.nxp.com>\n---\n drivers/bus/fslmc/fslmc_vfio.c | 66 +++++++++++++++++++++++++++++++---\n 1 file changed, 61 insertions(+), 5 deletions(-)", "diff": "diff --git a/drivers/bus/fslmc/fslmc_vfio.c b/drivers/bus/fslmc/fslmc_vfio.c\nindex 9134ec552..6dd797632 100644\n--- a/drivers/bus/fslmc/fslmc_vfio.c\n+++ b/drivers/bus/fslmc/fslmc_vfio.c\n@@ -802,10 +802,29 @@ fslmc_vfio_process_group(void)\n \tint ret;\n \tint found_mportal = 0;\n \tstruct rte_dpaa2_device *dev, *dev_temp;\n+\tbool is_dpmcp_in_blocklist = false, is_dpio_in_blocklist = false;\n+\tint dpmcp_count = 0, dpio_count = 0, current_device;\n+\n+\tTAILQ_FOREACH_SAFE(dev, &rte_fslmc_bus.device_list, next, dev_temp) {\n+\t\tif (dev->dev_type == DPAA2_MPORTAL) {\n+\t\t\tdpmcp_count++;\n+\t\t\tif (dev->device.devargs &&\n+\t\t\t dev->device.devargs->policy == RTE_DEV_BLACKLISTED)\n+\t\t\t\tis_dpmcp_in_blocklist = true;\n+\t\t}\n+\t\tif (dev->dev_type == DPAA2_IO) {\n+\t\t\tdpio_count++;\n+\t\t\tif (dev->device.devargs &&\n+\t\t\t dev->device.devargs->policy == RTE_DEV_BLACKLISTED)\n+\t\t\t\tis_dpmcp_in_blocklist = true;\n+\t\t}\n+\t}\n \n \t/* Search the MCP as that should be initialized first. */\n+\tcurrent_device = 0;\n \tTAILQ_FOREACH_SAFE(dev, &rte_fslmc_bus.device_list, next, dev_temp) {\n \t\tif (dev->dev_type == DPAA2_MPORTAL) {\n+\t\t\tcurrent_device++;\n \t\t\tif (dev->device.devargs &&\n \t\t\t dev->device.devargs->policy == RTE_DEV_BLACKLISTED) {\n \t\t\t\tDPAA2_BUS_LOG(DEBUG, \"%s Blacklisted, skipping\",\n@@ -815,13 +834,24 @@ fslmc_vfio_process_group(void)\n \t\t\t\tcontinue;\n \t\t\t}\n \n-\t\t\tret = fslmc_process_mcp(dev);\n-\t\t\tif (ret) {\n-\t\t\t\tDPAA2_BUS_ERR(\"Unable to map MC Portal\");\n-\t\t\t\treturn -1;\n+\t\t\tif (rte_eal_process_type() == RTE_PROC_SECONDARY &&\n+\t\t\t !is_dpmcp_in_blocklist) {\n+\t\t\t\tif (dpmcp_count == 1 ||\n+\t\t\t\t current_device != dpmcp_count) {\n+\t\t\t\t\tTAILQ_REMOVE(&rte_fslmc_bus.device_list,\n+\t\t\t\t\t\t dev, next);\n+\t\t\t\t\tcontinue;\n+\t\t\t\t}\n \t\t\t}\n-\t\t\tif (!found_mportal)\n+\n+\t\t\tif (!found_mportal) {\n+\t\t\t\tret = fslmc_process_mcp(dev);\n+\t\t\t\tif (ret) {\n+\t\t\t\t\tDPAA2_BUS_ERR(\"Unable to map MC Portal\");\n+\t\t\t\t\treturn -1;\n+\t\t\t\t}\n \t\t\t\tfound_mportal = 1;\n+\t\t\t}\n \n \t\t\tTAILQ_REMOVE(&rte_fslmc_bus.device_list, dev, next);\n \t\t\tfree(dev);\n@@ -838,7 +868,10 @@ fslmc_vfio_process_group(void)\n \t\treturn -1;\n \t}\n \n+\tcurrent_device = 0;\n \tTAILQ_FOREACH_SAFE(dev, &rte_fslmc_bus.device_list, next, dev_temp) {\n+\t\tif (dev->dev_type == DPAA2_IO)\n+\t\t\tcurrent_device++;\n \t\tif (dev->device.devargs &&\n \t\t dev->device.devargs->policy == RTE_DEV_BLACKLISTED) {\n \t\t\tDPAA2_BUS_LOG(DEBUG, \"%s Blacklisted, skipping\",\n@@ -846,6 +879,14 @@ fslmc_vfio_process_group(void)\n \t\t\tTAILQ_REMOVE(&rte_fslmc_bus.device_list, dev, next);\n \t\t\tcontinue;\n \t\t}\n+\t\tif (rte_eal_process_type() == RTE_PROC_SECONDARY &&\n+\t\t dev->dev_type != DPAA2_ETH &&\n+\t\t dev->dev_type != DPAA2_CRYPTO &&\n+\t\t dev->dev_type != DPAA2_QDMA &&\n+\t\t dev->dev_type != DPAA2_IO) {\n+\t\t\tTAILQ_REMOVE(&rte_fslmc_bus.device_list, dev, next);\n+\t\t\tcontinue;\n+\t\t}\n \t\tswitch (dev->dev_type) {\n \t\tcase DPAA2_ETH:\n \t\tcase DPAA2_CRYPTO:\n@@ -882,6 +923,21 @@ fslmc_vfio_process_group(void)\n \n \t\t\tbreak;\n \t\tcase DPAA2_IO:\n+\t\t\tif (!is_dpio_in_blocklist && dpio_count > 1) {\n+\t\t\t\tif (rte_eal_process_type() == RTE_PROC_SECONDARY\n+\t\t\t\t && current_device != dpio_count) {\n+\t\t\t\t\tTAILQ_REMOVE(&rte_fslmc_bus.device_list,\n+\t\t\t\t\t\t dev, next);\n+\t\t\t\t\tbreak;\n+\t\t\t\t}\n+\t\t\t\tif (rte_eal_process_type() == RTE_PROC_PRIMARY\n+\t\t\t\t && current_device == dpio_count) {\n+\t\t\t\t\tTAILQ_REMOVE(&rte_fslmc_bus.device_list,\n+\t\t\t\t\t\t dev, next);\n+\t\t\t\t\tbreak;\n+\t\t\t\t}\n+\t\t\t}\n+\n \t\t\tret = fslmc_process_iodevices(dev);\n \t\t\tif (ret) {\n \t\t\t\tDPAA2_BUS_DEBUG(\"Dev (%s) init failed\",\n", "prefixes": [ "v2", "2/8" ] }
