Hello Jeff,
Happy New Year to you and all.
In preparation for a future atl2 driver for the Atheros L2 10/100 chip,
we propose to move the existing atl1 driver to a new directory
(drivers/net/atlx), then split out functions and definitions that both
atl1 and atl2 can share. The final structure will look like this:
directory or file status
======================= ==========================
drivers/net/atl1/ deleted
drivers/net/atlx/ new
drivers/net/atlx/atl1.c atl1-specific functions
drivers/net/atlx/atl1.h atl1-specific definitions
drivers/net/atlx/atlx.c atl1-atl2 shared functions
drivers/net/atlx/atlx.h atl1-atl2 shared definitions
The first two patches submitted in this patchset accomplish the relocation
by movng the atl1 driver -- lock, stock, and barrel -- over to
drivers/net/atlx, then splitting out shareable functions and definitions.
Some transitory hackery will be present until the atl2 merge. Please
overlook it for now.
The remaining 24 patches bring the atl1 driver up to par with the current
vendor driver version 1.2.40.2. NAPI support is included and it seems
to work, but it needs to be scrutinized by an experienced eye. I had a
hard time finding much current NAPI documentation, so I just hacked at
it by looking at the e1000 driver.
Patch 02/26 is too large for LKML, so it's available at:
ftp://ftp.hogchain.net/pub/linux/attansic/atlx
Or, alternatively, the whole shebang can be pulled from:
git://git.hogchain.net/home/jcliburn/netdev-2.6.git atl1-for-jeff

1.5.3.3
From: Jay Cliburn <[email protected]>
The future atl2 driver and the existing atl1 driver can share certain
functions and definitions. Move these shareable functions and definitions
out of atl1-specific files and into atlx.c and atlx.h. Some transitory
hackery will be present until atl2 is merged.
Reduce the number of source files by moving ethtool, hw, and param
functions from separate files into atl1_main.c, then rename it to just
atl1.c.
Move all atl1-specific definitions from atl1_hw.h to atl1.h.
Finally, clean up to make checkpatch.pl happy.

From: Jay Cliburn <[email protected]>
In preparation for a future Atheros L2 NIC driver (called atl2), relocate
the atl1 driver into a new /drivers/net/atlx directory that will ultimately
be shared with the future atl2 driver.

the VLAN header; it's done later in a somewhat obscure fashion. Let's make
it clear from the top that we've allowed enough room for the VLAN header.

Check for null pointers and such in ring handling functions. Make
needlessly global functions static. Clean up some comments and indentation.

From: Jay Cliburn <[email protected]>
Add support for NAPI, styled after the e1000 NAPI implementation. That we
follow the e1000 for NAPI shouldn't come as much of a surprise, since the
entire atl1 driver is based heavily upon it.

1.5.3.3
From: Jay Cliburn <[email protected]>
The L1 tx packet descriptor expects TCP Header Length to be expressed as a
number of 32-bit dwords. The atl1 driver uses tcp_hdrlen() to populate the
field, but tcp_hdrlen() returns the header length in bytes, not in dwords.
Add a shift to convert tcp_hdrlen() to dwords when we write it to the tpd.
Also, some of our bit assignments are made to the wrong tpd words. Change
those to the correct words.
Finally, since all this fixes TSO, enable TSO by default.

All major netdevice functionality is now present in the atl1 driver. As
a result, remove the EXPERIMENTAL Kconfig tag in the main driver, but leave
it in the NAPI driver.

Hi Jay,
if buget == work_done is true, you should not call netif_rx_complete.
Searching recent netdev mailbox would be help.
Thanks.

Thanks for your comments Stephen and Joonwoo. Here's the revised
version of the atl1 NAPI patch.

Hi Jay,
+ if ((work_done < budget) || !netif_running(poll_dev)) {
+quit_polling:
+ netif_rx_complete(poll_dev, napi);
+
+ if (!test_bit(__ATL1_DOWN, &adapter->flags))
+ atlx_irq_enable(adapter);
+ }
Not enough :)
If netif_running() is false, it can make problem.
The problem occurs calling netif_rx_complete with work_done == budget.
If do that, net_rx_action would do poll list double deletion.
Since we had reached a consensus on fixing it without each drivers modifications, there is no best solution for that problem for
now. I'm expecting Dave or others work for net-core.
(http://lkml.org/lkml/2007/12/20/600)
IMHO, atl1_clean should wait for work_done != budget even though netif_running is false at this time.
At least, It would not make oops.
Thanks,
Joonwoo

Indeed, I really hope to try and close this out very soon.
Sorry for taking so long.

look into netif_msg_*, which enables via ethtool very fine-grained
selection of messages.

what does "less convoluted" mean?

same comments continue... these are software changes that need to be
explained.
"conform with vendor driver" does not excuse failure to document changes
in init and shutdown sequencing, for example.

Okay, I'll go back and rework the offending descriptions for this and
the other patches in this set.
> what does "less convoluted" mean?
I should have written "simpler," I suppose.
Before:
=======
struct tso_param {
u32 tsopu; /* tso_param upper word */
u32 tsopl; /* tso_param lower word */
};
struct csum_param {
u32 csumpu; /* csum_param upper word */
u32 csumpl; /* csum_param lower word */
};
union tpd_descr {
u64 data;
struct csum_param csum;
struct tso_param tso;
};
struct tx_packet_desc {
__le64 buffer_addr;
union tpd_descr desc;
};
After:
======
struct tx_packet_desc {
__le64 buffer_addr;
__le32 word2;
__le32 word3;
};

Since these changes are not simply moving code around, we really do need
full explanations for them, and to understand their need.
Blindly copying code from an exterior driver is pointless, and no way at
all to run an engineering process.
If the driver is not going to get the review and attention necessary,
bug fixes and feedback attended-to, then there's not much point in
having this driver in the kernel at all.
You will only lead yourself to frustration, if you set up a system where
changes only flow one way. That's not how Linux development is done at all.

No, sorry Jeff. I simply took the vendor's current driver and matched
his initialization settings. I can only assume he discovered these
values through lab testing.
For this and the other "conform to vendor driver" patches in this set, I
thought it important to have the in-tree driver match the vendor driver
as closely as possible. The primary motivations are (1) my belief that
he's in a better position to test the NIC, and (2) to be able to go to
him for assistance occasionally and not be rejected because of
significant differences between his and our drivers.

I don't think we should be doing this without justification. From all the atl1
and atl2 code I've looked at, I've gotten the impression that their driver
development processes are extremely ad-hoc. There is code in the Atheros
version of atl2 that cannot *possibly* apply to that hardware and was just
copied and pasted from atl1, just as much of atl1 was copied and pasted from
e1000. The fact that various versions have different magic numbers may simply
mean they copied and pasted from different irrelevant and incorrect sources.
Our contacts at Atheros seem to be very good electrical engineers, so when they
tell us that a certain setting should be changed to match particular properties
of the hardware, I trust them. They are not, however, experienced and
disciplined kernel developers, so absent such justification I think we should
stick with what we have, which has been improved and reviewed by people who
*are* experienced and disciplined kernel developers.
We have at least as much to teach Atheros about writing kernel code as they have
to teach us about their hardware.

Subject: [PATCH] atl1: simplify tx packet descriptor
The transmit packet descriptor consists of four 32-bit words, with word 3
upper bits overloaded depending upon the condition of its bits 3 and 4.
The driver currently duplicates all word 2 and some word 3 register bit
definitions unnecessarily and also uses a set of nested structures in its
definition of the TPD without good cause. This patch adds a lengthy
comment describing the TPD, eliminates duplicate TPD bit definitions,
and simplifies the TPD structure itself. It also expands the TSO check
to correctly handle custom checksum versus TSO processing using the revised
TPD definitions. Finally, shorten some variable names in the transmit
processing path to reduce line lengths, rename some variables to better
describe their purpose (e.g., nseg versus m), and add a comment or two
to better describe what the code is doing.
