From: Kamil Rytarowski Date: Fri, 30 Sep 2016 12:05:43 +0000 (+0200) Subject: net/thunderx/base: add secondary queue set support X-Git-Tag: spdx-start~5571 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=10b0e74f9995e25dd186e4fb0b383bf401624f85;p=dpdk.git net/thunderx/base: add secondary queue set support Changes: - add new message sqs_alloc in mailbox - add a queue container to hold secondary qsets. - add nicvf_mbox_request_sqs - handle new mailbox messages for secondary queue set support - register secondary queue sets for further reuse - register the number secondary queue sets in MSG_QS_CFG Signed-off-by: Maciej Czekaj Signed-off-by: Kamil Rytarowski Signed-off-by: Zyta Szpak Signed-off-by: Slawomir Rosek Signed-off-by: Radoslaw Biernacki Signed-off-by: Jerin Jacob --- diff --git a/drivers/net/thunderx/base/nicvf_hw_defs.h b/drivers/net/thunderx/base/nicvf_hw_defs.h index 2f2b225940..e144d44917 100644 --- a/drivers/net/thunderx/base/nicvf_hw_defs.h +++ b/drivers/net/thunderx/base/nicvf_hw_defs.h @@ -207,6 +207,7 @@ #define NICVF_CQE_RX2_RBPTR_WORD (7) #define NICVF_STATIC_ASSERT(s) _Static_assert(s, #s) +#define assert_primary(nic) assert((nic)->sqs_mode == 0) typedef uint64_t nicvf_phys_addr_t;
