We're trying to figure out a way of fixing netpoll. Don't know what the solution is yet. Here is what happens: in KGDB we set netpoll trapped flag. This prevents stopping and starting of a netdev queue. Interfaces that have a small ring (8139) run into a problem because of this. When the ring goes full, it can't stop the queue. This doesn't make sense since in absence of ring descriptors, the device can't transmit any more packets. Sergie had posted one more patch last week that lets us start and stop queues in trapped state. This patch fixes the 8139 side behavior in this context. -Amit - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
Re: [Kgdb-bugreport] [PATCH 2.6.20-rc7] 8139too KGDBoE fix
Hi Net Gurus,
This thread came up on kgdb-bugreport mailing list. Could you please suggest
us what's the correct way of fixing this problem?
1. When running a kgdb on RTL8139 ethernet interface: 8139too driver prints
too many "Out-of-sync dirty pointer" messages on console and gdb can't
connect to kgdb stub. These messages can be suppressed, though it still
results in connection failures frequently.
2. Here is how kgdb uses polling mechanism for communication to gdb. kgdb
calls netpoll_set_trap(1) just before entering a loop where it communicates
to gdb. It calls netpoll_set_trap(0) after it is done and wants to resume a
kernel. The communication to gdb goes through netpoll_poll (which calls kgdb
rx_hook) and netpoll_send_udp functions.
3. A queue for an interface may have been stopped by it's driver by calling
netif_stop_queue. After this if kgdb attempts to enter communication with
gdb, it'll call netpoll_set_trap(1), after which the queue can't be started
again. This is a potential deadlock situation. Is there a way out of this?
4. Is it necessary to call netpoll_set_trap(1) at all before entering gdb
communication loop? Even if a driver stops the queue in middle of the
communication netpoll_poll and netpoll_send_udp calls can recover from that
by calling driver's interrupt and poll routines. Is this a valid statement?
Thanks a lot.
-Amit

[PATCH 0/3] NetXen: 1G/10G Ethernet Driver updates
Hi All, I will be sending NetXen: 1G/10G Ethernet Driver updates with respect to netdev #master in the subsequent emails. We have incorporated the feedbacks we got for the patch on the ethtool support for user level tools, except for these: Jeff Garzik wrote: >is it ok to return without re-locking flash? After flashing, we have to reboot the machine before we can use the newer flash. So re-locking is not necessary. Also its not possible to detect the end of flashing process, so as to lock the flash after that. >> netxen_nic_reg_write(adapter, NETXEN_ROMUSB_ROM_ABYTE_CNT, 0); >> - udelay(100);/* prevent bursting on CRB */ >> + udelay(70); /* prevent bursting on CRB */ Jeff Garzik wrote: >why? This is only to reduce the flashing time.

[PATCH 0/2] NetXen: NetXen 1G/10G Ethernet Driver updates
Hi All, I will be sending NetXen: 1G/10G Ethernet Driver updates in subsequent emails. Thanks, --Amit - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
[PATCH 2/2] NetXen: Use pci_register_driver() instead of pci_module_init() in init_module
I am extremely sorry for sending this patch with wrong subject line before this.
Now i am resending the patch with correct line.
Thanks,
--Amit
This will use pci_register_driver() instead of pci_module_init().

Any kind of reservation may result in underutilization and transparently shared resources may result in starvation. Designing heuristics for handling these cases may be the only possible wayout, though these heuristics need to be validated frequently to ensure that they aren't out of date. -Amit - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
Re: network devices don't handle pci_dma_mapping_error()'s
We can let a driver handle dma mapping errors using these-> 1.Reduce the size of a receive ring. This will free some possibly remapped memory, reducing pressure on iommu. We also need to printk a message so that a user knows the reason why receive ring was shrunk. Growing it when iommu pressure goes down will result in a ping-pong. 2. Force processing of receive and transmit ring. This will ensure that the buffers processed by hardware are freed, reducing iommu pressure. 3. If we need to do (1) and (2) a predefined number of times (say 20), stop the queue. Stopping the queue in general will cause a ping-pong, so it should be avoided as far as possible. -Amit On Thursday 07 December 2006 06:28, Stephen Hemminger wrote: > The more robust way would be to stop the queue (like flow control) > and return busy.

We've seen IOMMU space running out on ia64 systems. Would this be the case with other 10G driver requiring IOMMU remapping? We need frequent map-unmap at near 10G throughput. On the x86_64 boxes that don't feature iommu functionality (because the motherboard disables it or because Linux can't handle it) Linux bounce buffer framework automatically comes into picture. Could we have the same framework take over when IOMMU space is over? I don't think this is possible with present code, though. We probably can have fallback_dma_ops in addition to dma_ops. -Amit - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
Re: [PATCH] netxen: sparse warning and ioctl bug fixes
Hi Stephen,
This patch looks good.
ioctls: NetXen chip is far more generic and will eventually show a significant
amount of functionality in different products. We need ioctl analysis for
user level tools that can tell states of registers etc. Removing ioctls all
together will make any analysis from userland extremely difficult.
Does anyone have ideas on improving this ioctl interface?
Thanks.
-Amit

The intent is to > > enable DMA into addresses upto 32G. > > > > You should then set the same value for pci_set_dma_mask, because then the IOMMU > can help. See both b44 or tg3 drivers, they have to deal with odd size masks. > I don't think you have to do all the bounce buffer work in the driver. Using bounce buffers has following tradeoffs: 1. Overhead of code maintenance. 2. Slow performance. Also on some ia64 machines we saw reduced performance because of larger ring sizes. But if we remove bounce buffers and use IOMMU instead, it might not work for some Opteron configurations. On one of our Opterons we could not set the IOMMU from kernel command line (it asked to set it from the BIOS where there was no such option in the BIOS) So what do you suggest, should we use the IOMMU or should we keep the bounce buffers as they are?

[PATCH 2.6.17 0/9] NetXen: 1G/10G Ethernet Driver
Hi All, Thank you Stephen, Don and Wendy. We have incorporated feedbacks which have received since after last post. I'll be resending updated patchset in subsequent emails. We are working on finding out good way of using tables to manage compatibility between firmware version number and driver version number. Kindly review it and feel free to send feedback.

By locking the firmware and > driver version together you might make maintenance more difficult. Ah, I had missed that completely in your first email. Thanks for your suggestion. The NetXen firmware will most probably keep changing. It's hardware is flexible enough, so the firmware changes will possibly be varied in nature. Thinking about this further, it seems we should coalesce firmware dependent code into a few isolated functions. While this may be difficult, we should do it anyway. Hopefully future changes will not cause these efforts to go waste. -Amit - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Instead just use original format. net_device structure contains "unsigned long" fields. netxen_port_stats contains u64 fields. rx_bytes and tx_bytes can easily overflow for 10G cards. ethtool_status contains u64 stats; is it a good time to make net_device_stats 64 bit? -Amit - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
Re: [PATCH 2.6.17 2/9] NetXen: Hardware access routines
We can certainly create a table for all error messages. It'll hurt readability
of code in many of the other places where printks are used to indicate some
hardware error.
