Subject: [dpdk-dev] [PATCH v3] eal: increase max number of interrupt vectors
Date: Sun, 31 Mar 2019 14:55:20 +0000 [thread overview]
Message-ID: <20190331145452.4144-1-pbhagavatula@marvell.com> (raw)
Message-ID: <20190331145520.45qxj70p3aym8jNbKTytBd__CrH1Dm_-3Oib0SsvIs8@z> (raw)
In-Reply-To: <20190326125327.5264-1-pbhagavatula@marvell.com>
From: Pavan Nikhilesh <pbhagavatula@marvell.com>
MSI-X permits a device to allocate up to 2048 interrupts as per PCIe
spec.
Increase the max number of vectors to a reasonable value of 512.
Signed-off-by: Pavan Nikhilesh <pbhagavatula@marvell.com>
---
v3 Changes:
- Instead of making it a configurable option set max vectors to a reasonable
value of 512.
v2 Changes:
- Add defaults for meson build. (Jerin Jacob)
