From: Rasesh Mody Date: Sat, 7 Oct 2017 06:31:02 +0000 (-0700) Subject: net/qede/base: add various OS abstraction macros X-Git-Tag: spdx-start~1550 X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=70f1a93d7b184d27566bb6cfa979a19f72f91e40 net/qede/base: add various OS abstraction macros - Introduce OSAL_IOV_VF_VPORT_STOP to allow VF to carry out required operations and prevent a potential assert before closing vport - Add OSAL_DIV_S64() for 64-bit division on 32-bit platforms. - Add OSAL for transceiver update OSAL_TRANSCEIVER_UPDATE() - Add OSAL for MFW command preemption OSAL_MFW_CMD_PREEMPT() within the spinning loops while sending a mailbox command to the MFW - Implement OSAL_SPIN_LOCK_IRQSAVE macro - Rename OSAL_NUM_ACTIVE_CPU() to OSAL_NUM_CPUS() Signed-off-by: Rasesh Mody --- diff --git a/drivers/net/qede/base/bcm_osal.h b/drivers/net/qede/base/bcm_osal.h index 47290f4be1..74e5188216 100644 --- a/drivers/net/qede/base/bcm_osal.h +++ b/drivers/net/qede/base/bcm_osal.h @@ -46,6 +46,8 @@ void qed_link_update(struct ecore_hwfn *hwfn, struct ecore_ptt *ptt); #define OSAL_WARN(arg1, arg2, arg3, ...)
