To: davem, netdev; +Cc: adapter_linux_open_src_team, Rasesh Mody
Change details:
- This patch contains removal of get_regs support in bnad_ethtool.c. Thus
BNA will have minimal register definitions necessary for MBOX and
interrupt operations

To: davem, netdev; +Cc: adapter_linux_open_src_team, Rasesh Mody
Change details:
- Introducing new file bfi_reg.h for consolidating all supported hardware
registers. This file completely replaces bfi_ctreg.h.
- Updated ioc code as per register definition change.

To: davem, netdev; +Cc: adapter_linux_open_src_team, Rasesh Mody
Change details:
- Currently modules communicate with the FW using 32 byte command and
response register. This limits the size of the command and response
messages exchanged with the FW to 32 bytes. We need a mechanism to
exchange the comamnds and responses exchange with FW that exceeds 32 bytes.
- MSGQ implementation provides that facility. It removes the assumption that
command/response queue size is precisely calculated to accommodate all
concurrent FW commands/responses. The queue depth is made variable now, defined
by a macro. A waiting command list is implemented to hold all the commands
when there is no place in the command queue. Callback is implemented for
each command entry to invoke the module posting the command, when there is
space in the command queue and the command was finally posted to the queue.
Module/Object information is embedded in the response for tracking purpose.

5 siblings, 0 replies; 10+ messages in thread
From: Rasesh Mody @ 2011-08-01 20:42 UTC (permalink / raw)
To: davem, netdev; +Cc: adapter_linux_open_src_team, Rasesh Mody
Change details:
- This patch contains the messages, opcodes and structure format for the
messages and responses exchanged between driver and the FW. In addition
this patch contains the state machine implementation for Ethport, Enet,
IOCEth.
- Ethport object is responsible for receiving link state events, sending
port enable/disable commands to FW.
- Enet object is responsible for synchronizing initialization/teardown of
tx & rx datapath configuration.
- IOCEth object is responsible for init/un-init of IO Controller in the
adapter which runs the FW.
- This patch also contains code for initialization and resource assignment
for Ethport, Enet, IOCEth, Tx, Rx objects.

To: davem, netdev; +Cc: adapter_linux_open_src_team, Rasesh Mody
Change details:
- This patch contains the changes as a result of redesigning of Tx, Rx data
path setup. In the old design, setting up Txqs, Rxqs were done in the driver.
With the new design, most of the hardware setup steps for the Txq, Rxqs are
moved to FW. Host driver issues commands to FW through the message queue to
setup/teardown tx, rx data path. FW performs necessary steps and responds
back to the driver with a status.
- As a result of this redesign, the state machine implementation for Tx, Rx
objects have changed significantly. Instead of doing the raw register access,
these state machines mostly send a command to FW and wait for response and
take the next action. In addition to tx, rx datapath setup, this patch also
deals with rx filter configuration - such as unicast address, multicast
address, vlan filter, promiscuous mode etc.

This just adds a lot of new code, but there are no users of this
new code.
Resubmit this when you have the actual users of the code ready.
I'm not applying this entire patch series.

We took this approach to avoid sending large amount of patches at once while keeping the patches bisectable.
We can resubmit the first 3 patches as enhancements and submit new code in a separate patch set with actual user of the code, but the patch count may be little high for this new code enablement, is this ok?
Thanks,
Rasesh
