Subject: [dpdk-dev] [PATCH v9 1/5] eal: add a new generic helper for wait scheme
Date: Mon,  1 Nov 2021 14:00:03 +0800
Message-ID: <20211101060007.2632418-2-feifei.wang2@arm.com> (raw)
In-Reply-To: <20211101060007.2632418-1-feifei.wang2@arm.com>

Add a new generic helper which is a macro for wait scheme.

Furthermore, to prevent compilation warning in arm:
----------------------------------------------
'warning: implicit declaration of function ...'
----------------------------------------------
Delete 'undef' constructions for '__LOAD_EXC_xx', '__SEVL' and '__WFE'.
And add ‘__RTE_ARM’ for these macros to fix the namespace.
This is because original macros are undefine at the end of the file.
If new macro 'rte_wait_event' calls them in other files, they will be
seen as 'not defined'.
