2006-10-16[PATCH] bcm43xx-softmac: Fix system hang for x86-64 with >1GB RAMLarry Finger
The bcm43xx-softmac software currently fails when running on x86_64 systems with more than 1GB RAM and one of the card variants with 30-bit DMA addressing. This patch uses the address extension bits in the hardware to set the correct DMA mask for the specific card in use. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.

2006-10-16[PATCH] bcm43xx-softmac: check returned value from pci_enable_deviceLarry Finger
Linus's tree now has a configuration option that prints a warning whenever the returned value of any routine is ignored. This patch fixes the only such warning for bcm43xx. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2006-10-16[PATCH] bcm43xx: fix race condition in periodic work handlerMichael Buesch
There is a potential race condition in the periodic_work_handler routine of bcm43xx-softmac. In addition to fixing this condition, the size of code is reduced by moving the mutex lock outside the if.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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.

2006-09-27[PATCH] inode_diet: Replace inode.u.generic_ip with inode.i_privateTheodore Ts'o
The following patches reduce the size of the VFS inode structure by 28 bytes on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.

Johann Uhrmann reported a bcm43xx crash and Michael Buesch tracked it down to a problem with the new shared key auth code (recursive calls into the driver) This patch (effectively Michael's patch with a couple of small modifications) solves the problem by sending the authentication challenge response frame from a workqueue entry.

2006-07-10[PATCH] bcm43xx: improved statisticsLarry Finger
This patch improves the statistics returned from bcm43xx_get_wireless_stats. The signal level comes from smoothing the "rssi" value returned by the firmware after it is converted into a dBm value by the driver. The quality value is a hack derived from the smoothed level and an assumed RX_POWER_MAX of -10 dBM. The noise value is still the one calculated from the clean-room formula. On my system, this is roughly -65 dBm, which seems too high. The revised version uses the ieee80211 spinlock to protect traversing of the network list.
