Hi Roland, everyone
This series includes fixes for two bugs in the SRIOV code which were discovered
in
production environment, lets get them upstream too...
Also, a respin of the 64B CQE/EQE patches (kernel and user-space), over the V1
posting
you were asking for max flexibility - e.g expose/force update of guests only if
needed
and similarily for libmlx4, I think I have this now, would love feedback though.
I tested this with both modified/non-modified mlx4 guest drivers, and with
both modified/non-modified libmlx4. The only pain point I was hitting,
if non modified libmlx4 on systems with CX3 and modified kernel, on
the V1 discussion Roland -- you made a comment we might need a module param
here to provide admins a way to let systems with old libmlx4 to work
with fresh kernels?!
changes from previous versions to the kernel 64B CQE/EQE patch:
V0 pointer
mlx4 http://marc.info/?l=linux-rdma&m=131805712306677&w=2
libmlx4 http://marc.info/?l=linux-rdma&m=131805712306678&w=2
V1 pointer
mlx4 http://marc.info/?l=linux-rdma&m=133787002203027&w=2
libmlx4 -- didn't have V1
V1 changes from V0:
- unified the 64B CQE and EQE patches to one patch which takes an approach of
apply both or none, under the thinking that 99% FW will support both or none.
- bump the ABI version towards user-space/libmlx4 only when needed and not
always
- added support for SRIOV, using the PF_CONTEXT_BEHAVIOUR_MASK mechanism
V2 changes:
- rebased to kernel 3.6+ (e.g pre 3.7-rc1) that includes the SRIOV/IB patches
- revised/fixed the SRIOV flow
- revises/fixed the flow towards user-space

changes from the previous version to the libmlx4 patch
- added storing per device ABI
- added handling ABI version 4 and also older ABI versions w.r.t to
struct mlx4_alloc_ucontext_resp_v3
