* fix vlan in 8139cp on big-endianAl Viro2007-10-101-5/+5
| | | | | | | | | | | | | Layout of opts2 is : MSB(vlan_tag) : LSB(vlan_tag) : flags : 0 : regardless of the host endianness. On little-endian the current code ends up with the right values, but on big-endian it blows. In r8169.c the same bug had been fixed in commit d35da12a40426184b1d0844104b1d464753eba19 (r8169: endianness fixes).

* [ETHTOOL] Provide default behaviors for a few ethtool sub-ioctlsJeff Garzik2007-10-101-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | For the operations get-tx-csum get-sg get-tso get-ufo the default ethtool_op_xxx behavior is fine for all drivers, so we permit op==NULL to imply the default behavior. This provides a more uniform behavior across all drivers, eliminating ethtool(8) "ioctl not supported" errors on older drivers that had not been updated for the latest sub-ioctls. The ethtool_op_xxx() functions are left exported, in case anyone wishes to call them directly from a driver-private implementation -- a not-uncommon case. Should an ethtool_op_xxx() helper remain unused for a while, except by net/core/ethtool.c, we can un-export it at a later date.

* [NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger2007-10-101-20/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device.

* | PCI: Change all drivers to use pci_device->revisionAuke Kok2007-07-111-5/+2
|/ | | | | | | | | | | | | | | | | | | | Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance.

* 8139cp: Don't blindly enable interruptsChris Lalancette2007-01-181-3/+4
| | | | | | | | | | | | | | | | | | | | | Similar to this commit: http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d15e9c4d9a75702b30e00cdf95c71c88e3f3f51e It's not safe in cp_start_xmit to blindly call spin_lock_irq and then spin_unlock_irq, since it may very well be the case that cp_start_xmit was called with interrupts already disabled (I came across this bug in the context of netdump in RedHat kernels, but the same issue holds, for example, in netconsole). Therefore, replace all instances of spin_lock_irq and spin_unlock_irq with spin_lock_irqsave and spin_unlock_irqrestore, respectively, in cp_start_xmit(). I tested this against a fully-virtualized Xen guest using netdump, which happens to use the 8139cp driver to talk to the emulated hardware. I don't have a real piece of 8139cp hardware to test on, so someone else will have to do that. Signed-off-by: Chris Lalancette <clalance@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-051-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

| | | | | | | | | | | | | | | | | | | | | | | | Having separate fields in sk_buff for TSO/UFO (tso_size/ufo_size) is not going to scale if we add any more segmentation methods (e.g., DCCP). So let's merge them. They were used to tell the protocol of a packet. This function has been subsumed by the new gso_type field. This is essentially a set of netdev feature bits (shifted by 16 bits) that are required to process a specific skb. As such it's easy to tell whether a given device can process a GSO skb: you just have to and the gso_type field and the netdev's features field. I've made gso_type a conjunction. The idea is that you have a base type (e.g., SKB_GSO_TCPV4) that can be modified further to support new features. For example, if we add a hardware TSO type that supports ECN, they would declare NETIF_F_TSO | NETIF_F_TSO_ECN. All TSO packets with CWR set would have a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO packets would be SKB_GSO_TCPV4. This means that only the CWR packets need to be emulated in software. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [PATCH] 8139cp: add ethtool eeprom supportPhilip Craig2006-06-221-12/+167
| | | | | | | | Implement the ethtool eeprom operations for the 8139cp driver. Tested on x86 and big-endian ARM. Signed-off-by: Philip Craig <philipc@snapgear.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] 8139cp: fix eeprom read command lengthPhilip Craig2006-06-221-1/+1
| | | | | | | | | The read command for the 93C46/93C56 EEPROMS should be 3 bits plus the address. This doesn't appear to affect the operation of the read command, but similar errors for write commands do cause failures.
