From 0b7ca5a928e2271bbc225e9e1ac1f22e9fbee54f Mon Sep 17 00:00:00 2001 From: Yevgeny Petrilin Date: Tue, 22 Mar 2011 22:37:47 +0000 Subject: mlx4: Changing interrupt scheme Adding a pool of MSI-X vectors and EQs that can be used explicitly by mlx4_core customers (mlx4_ib, mlx4_en). The consumers will assign their own names to the interrupt vectors. Those vectors are not opened at mlx4 device initialization, opened by demand. Changed the max number of possible EQs according to the new scheme, no longer relies on on number of cores. The new functionality is exposed through mlx4_assign_eq() and mlx4_release_eq(). Customers that do not use the new API will get completion vectors as before. Signed-off-by: Markuze Alex Signed-off-by: Yevgeny Petrilin Signed-off-by: David S.
