CN9K getwork mode by default is set to use dual workslot mode. Add option to force single workslot mode. Example: --dev "0002:0e:00.0,single_ws=1" CN10K supports multiple getwork prefetch modes, by default the prefetch mode is set to none. Add option to select getwork prefetch mode Example: --dev "0002:1e:00.0,gw_mode=1" Signed-off-by: Pavan Nikhilesh Signed-off-by: Shijith Thotton --- doc/guides/eventdevs/cnxk.rst | 18 ++++++++++++++++++ drivers/event/cnxk/cn10k_eventdev.c | 3 ++- drivers/event/cnxk/cn9k_eventdev.c | 3 ++- drivers/event/cnxk/cnxk_eventdev.c | 6 ++++++ drivers/event/cnxk/cnxk_eventdev.h | 6 ++++-- 5 files changed, 32 insertions(+), 4 deletions(-) diff --git a/doc/guides/eventdevs/cnxk.rst b/doc/guides/eventdevs/cnxk.rst index cf2156333..b2684d431 100644 --- a/doc/guides/eventdevs/cnxk.rst +++ b/doc/guides/eventdevs/cnxk.rst @@ -55,6 +55,24 @@ Runtime Config Options -a 0002:0e:00.0,xae_cnt=16384 +- ``CN9K Getwork mode`` + + CN9K ``single_ws`` devargs parameter is introduced to select single workslot + mode in SSO and disable the default dual workslot mode. + + For example:: + + -a 0002:0e:00.0,single_ws=1 + +- ``CN10K Getwork mode`` + + CN10K supports multiple getwork prefetch modes, by default the prefetch + mode is set to none. + + For example:: + + -a 0002:0e:00.0,gw_mode=1 + - ``Event Group QoS support`` SSO GGRPs i.e. queue uses DRAM & SRAM buffers to hold in-flight diff --git a/drivers/event/cnxk/cn10k_eventdev.c b/drivers/event/cnxk/cn10k_eventdev.c index 3cf07734b..310acc011 100644 --- a/drivers/event/cnxk/cn10k_eventdev.c +++ b/drivers/event/cnxk/cn10k_eventdev.c @@ -327,4 +327,5 @@ RTE_PMD_REGISTER_PCI(event_cn10k, cn10k_pci_sso); RTE_PMD_REGISTER_PCI_TABLE(event_cn10k, cn10k_pci_sso_map); RTE_PMD_REGISTER_KMOD_DEP(event_cn10k, "vfio-pci"); RTE_PMD_REGISTER_PARAM_STRING(event_cn10k, CNXK_SSO_XAE_CNT "=" - CNXK_SSO_GGRP_QOS "="); + CNXK_SSO_GGRP_QOS "=" + CN10K_SSO_GW_MODE "="); diff --git a/drivers/event/cnxk/cn9k_eventdev.c b/drivers/event/cnxk/cn9k_eventdev.c index 5be2776cc..44c7a0c3a 100644 --- a/drivers/event/cnxk/cn9k_eventdev.c +++ b/drivers/event/cnxk/cn9k_eventdev.c @@ -395,4 +395,5 @@ RTE_PMD_REGISTER_PCI(event_cn9k, cn9k_pci_sso); RTE_PMD_REGISTER_PCI_TABLE(event_cn9k, cn9k_pci_sso_map); RTE_PMD_REGISTER_KMOD_DEP(event_cn9k, "vfio-pci"); RTE_PMD_REGISTER_PARAM_STRING(event_cn9k, CNXK_SSO_XAE_CNT "=" - CNXK_SSO_GGRP_QOS "="); + CNXK_SSO_GGRP_QOS "=" + CN9K_SSO_SINGLE_WS "=1"); diff --git a/drivers/event/cnxk/cnxk_eventdev.c b/drivers/event/cnxk/cnxk_eventdev.c index 5f4075a31..0e2cc3681 100644 --- a/drivers/event/cnxk/cnxk_eventdev.c +++ b/drivers/event/cnxk/cnxk_eventdev.c @@ -406,6 +406,7 @@ static void cnxk_sso_parse_devargs(struct cnxk_sso_evdev *dev, struct rte_devargs *devargs) { struct rte_kvargs *kvlist; + uint8_t single_ws = 0; if (devargs == NULL) return; @@ -417,6 +418,11 @@ cnxk_sso_parse_devargs(struct cnxk_sso_evdev *dev, struct rte_devargs *devargs) &dev->xae_cnt); rte_kvargs_process(kvlist, CNXK_SSO_GGRP_QOS, &parse_sso_kvargs_dict, dev); + rte_kvargs_process(kvlist, CN9K_SSO_SINGLE_WS, &parse_kvargs_value, + &single_ws); + rte_kvargs_process(kvlist, CN10K_SSO_GW_MODE, &parse_kvargs_value, + &dev->gw_mode); + dev->dual_ws = !single_ws; rte_kvargs_free(kvlist); } diff --git a/drivers/event/cnxk/cnxk_eventdev.h b/drivers/event/cnxk/cnxk_eventdev.h index bf2c961aa..85f6058f2 100644 --- a/drivers/event/cnxk/cnxk_eventdev.h +++ b/drivers/event/cnxk/cnxk_eventdev.h @@ -14,8 +14,10 @@ #include "roc_api.h" -#define CNXK_SSO_XAE_CNT "xae_cnt" -#define CNXK_SSO_GGRP_QOS "qos" +#define CNXK_SSO_XAE_CNT "xae_cnt" +#define CNXK_SSO_GGRP_QOS "qos" +#define CN9K_SSO_SINGLE_WS "single_ws" +#define CN10K_SSO_GW_MODE "gw_mode" #define NSEC2USEC(__ns) ((__ns) / 1E3) #define USEC2NSEC(__us) ((__us)*1E3) -- 2.17.1
