2005-08-30[PATCH] Create vio_bus_opsStephen Rothwell
Create vio_bus_ops so that we just pass a structure to vio_bus_init instead of three separate function pointers. Rearrange vio.h to avoid forward references. vio.h only needs struct device_node from prom.h so remove the include and just declare it.

2005-08-29[BNX2]: update version and minor fixesMichael Chan
Update version and add 4 minor fixes, the last 2 were suggested by Jeff Garzik: 1. check for a valid ethernet address before setting it 2. zero out bp->regview if init_one encounters an error and unmaps the IO address. This prevents remove_one from unmapping again. 3. use netif_rx_schedule() instead of hand coding the same. 4. use IRQ_HANDLED and IRQ_NONE.

2005-08-29[BNX2]: remove atomics in txMichael Chan
Remove atomic operations in the fast tx path. Expensive atomic operations were used to keep track of the number of available tx descriptors. The new code uses the difference between the consumer and producer index to determine the number of free tx descriptors. As suggested by Jeff Garzik, the name of the inline function is changed to all lower case. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[BNX2]: speedup serdes linkupMichael Chan
This speeds up link-up time on 5706 SerDes if the link partner does not autoneg, a rather common scenario in blade servers. Some blade servers use IPMI for keyboard input and it's important to minimize link disruptions. The speedup is achieved by shortening the timer to (HZ / 3) during the transient period right after initiating a SerDes autoneg. If autoneg does not complete, parallel detect can be done sooner. After the transient period is over, the timer goes back to its normal HZ interval. As suggested by Jeff Garzik, the timer initialization is moved to bnx2_init_board() from bnx2_open(). An eeprom bit is also added to allow default forced SerDes speed for even faster link-up time. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[BNX2]: Fix rtnl deadlock in bnx2_closeMichael Chan
This fixes an rtnl deadlock problem when flush_scheduled_work() is called from bnx2_close(). In rare cases, linkwatch_event() may be on the workqueue from a previous close of a different device and it will try to get the rtnl lock which is already held by dev_close(). The fix is to set a flag if we are in the reset task which is run from the workqueue. bnx2_close() will loop until the flag is cleared. As suggested by Jeff Garzik, the loop is changed to call msleep(1) instead of yield() in the original patch. flush_scheduled_work() is also moved to bnx2_remove_one() before the netdev is freed.

2005-08-29[TG3]: Fix bug in setting a tg3_flagMichael Chan
Found a bug while reviewing the patches the second time. The TG3_FLAG_TXD_MBOX_HWBUG flag is set after the register access methods have been determined.

2005-08-29[TG3]: Eliminate one register write in tg3_restart_ints()Michael Chan
The register write to register 0x68 to restart interrupts is unnecessary as the interrupt wasn't masked in that register by the irq handler. This will save one register write in the fast path. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[TG3]: Add indirect register method for 5703 behind ICHMichael Chan
This patch adds the new workaround for 5703 A1/A2 if it is behind certain ICH bridges. The workaround disables memory and uses config. cycles only to access all registers. The 5702/03 chips can mistakenly decode the special cycles from the ICH chipsets as memory write cycles, causing corruption of register and memory space. Only certain ICH bridges will drive special cycles with non-zero data during the address phase which can fall within the 5703's address range. This is not an ICH bug as the PCI spec allows non-zero address during special cycles. However, only these ICH bridges are known to drive non-zero addresses during special cycles. The indirect_lock is also changed to spin_lock_irqsave from spin_lock_bh because it is used in irq handler when using the indirect method to disable interrupts.

2005-08-29[TG3]: Add basic register access function pointersMichael Chan
This patch adds the basic function pointers to do register accesses in the fast path. This was suggested by David Miller. The idea is that various register access methods for different hardware errata can easily be implemented with these function pointers and performance will not be degraded on chips that use normal register access methods. The various register read write macros (e.g. tw32, tr32, tw32_mailbox) are redefined to call the function pointers. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

2005-08-29[NET]: Kill skb->real_devDavid S. Miller
Bonding just wants the device before the skb_bond() decapsulation occurs, so simply pass that original device into packet_type->func() as an argument.

2005-08-29[NET]: Remove HIPPI private from skbuff.hStephen Hemminger
This removes the private element from skbuff, that is only used by HIPPI. Instead it uses skb->cb[] to hold the additional data that is needed in the output path from hard_header to device driver. PS: The only qdisc that might potentially corrupt this cb[] is if netem was used over HIPPI. I will take care of that by fixing netem to use skb->stamp. I don't expect many users of netem over HIPPI Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[NET]: Kill skb->listDavid S. Miller
Remove the "list" member of struct sk_buff, as it is entirely redundant. All SKB list removal callers know which list the SKB is on, so storing this in sk_buff does nothing other than taking up some space.

2005-08-27[PATCH] Remove race between con_open and con_closePaul Mackerras
[ Same race and same patch also by Steven Rostedt <rostedt@goodmis.org> ] I have a laptop (G3 powerbook) which will pretty reliably hit a race between con_open and con_close late in the boot process and oops in vt_ioctl due to tty->driver_data being NULL. What happens is this: process A opens /dev/tty6; it comes into con_open() (drivers/char/vt.c) and assign a non-NULL value to tty->driver_data. Then process A closes that and concurrently process B opens /dev/tty6. Process A gets through con_close() and clears tty->driver_data, since tty->count == 1. However, before process A can decrement tty->count, we switch to process B (e.g. at the down(&tty_sem) call at drivers/char/tty_io.c line 1626). So process B gets to run and comes into con_open with tty->count == 2, as tty->count is incremented (in init_dev) before con_open is called. Because tty->count != 1, we don't set tty->driver_data. Then when the process tries to do anything with that fd, it oopses. The simple and effective fix for this is to test tty->driver_data rather than tty->count in con_open. The testing and setting of tty->driver_data is serialized with respect to the clearing of tty->driver_data in con_close by the console_sem. We can't get a situation where con_open sees tty->driver_data != NULL and then con_close on a different fd clears tty->driver_data, because tty->count is incremented before con_open is called. Thus this patch eliminates the race, and in fact with this patch my laptop doesn't oops.
