2008-01-30x86: unify struct desc_ptrGlauber de Oliveira Costa
This patch unifies struct desc_ptr between i386 and x86_64. They can be expressed in the exact same way in C code, only having to change the name of one of them. As Xgt_desc_struct is ugly and big, this is the one that goes away. There's also a padding field in i386, but it is not really needed in the C structure definition.

2008-01-30x86: assign IRQs to HPET timers, fixBalaji Rao
Looks like IRQ 31 is assigned to timer 3, even without the patch! I wonder who wrote the number 31. But the manual says that it is zero by default. I think we should check whether the timer has been allocated an IRQ before proceeding to assign one to it. Here is a patch that does this.

2008-01-30x86: assign IRQs to HPET timersBalaji Rao
The userspace API for the HPET (see Documentation/hpet.txt) did not work. The HPET_IE_ON ioctl was failing as there was no IRQ assigned to the timer device. This patch fixes it by allocating IRQs to timer blocks in the HPET. arch/x86/kernel/hpet.c | 13 +++++-------- drivers/char/hpet.c | 45 ++++++++++++++++++++++++++++++++++++++------- include/linux/hpet.h | 2 +- 3 files changed, 44 insertions(+), 16 deletions(-) Signed-off-by: Balaji Rao <balajirrao@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

The new e1000e driver is apparently not yet suitable for general use, so mark it experimental, and re-instate all the PCI-Express device IDs in the old and stable e1000 driver so that people (namely me) can continue to use a driver that actually works.

2008-01-28ath5k: configure backoff for IBSS beacon queueBruno Randolf
in "11.1.2.2 Beacon generation in an IBSS" the IEEE802.11 standard says, each STA should... "b) Calculate a random delay uniformly distributed in the range between zero and twice aCWmin × aSlotTime,". configure cwmin and cwmax of the beacon queue in IBSS mode according to this. unfortunately beacon backoff does not work reliably yet, so i suspect we have a problem somewhere else, since the same settings (and similar beacon timer configuration) work for madwifi. drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD Signed-off-by: Bruno Randolf <bruno@thinktube.com> Signed-off-by: John W.

2008-01-28ath5k: use SWBA to detect IBSS HW mergesBruno Randolf
use SWBA (software beacon alert) interrupts to keep track of the next beacon time und check if a HW merge (automatic TSF update) has happened on every received beacon with the same BSSID. this is necessary because the atheros hardware will silently update the local TSF in IBSS mode, but not its beacon timers. if the TSF is ahead of the beacon timers no beacons are sent until the timers wrap around (typically after about 1 minute). this solution is not very nice, since we have to look into every beacon, but there is apparently no other way to detect HW merges. drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD drivers/net/wireless/ath5k/base.h: Changes-licensed-under: 3-Clause-BSD Signed-off-by: Bruno Randolf <bruno@thinktube.com> Signed-off-by: John W.

2008-01-28b43: Fix MAC control and microcode initMichael Buesch
This zeros out all microcode related memory before loading the microcode. This also fixes initialization of the MAC control register. The _only_ place where we overwrite the contents of the MAC control register is at the beginning of b43_chip_init(). All other places must do read() -> mask/set -> write() to not overwrite existing bits. This also adds a longer delay for waiting for the microcode to initialize itself. It seems that the current timeout is sufficient on all available devices, but there's no real reason why we shouldn't wait for up to one second. Slow embedded devices might exist.

2008-01-28igb: PCI-Express 82575 Gigabit Ethernet driverAuke Kok
We are pleased to announce a new Gigabit Ethernet product and its driver to the linux community. This product is the Intel(R) 82575 Gigabit Ethernet adapter family. Physical adapters will be available to the public soon. These adapters come in 2- and 4-port versions (copper PHY) currently. Other variants will be available later. The 82575 chipset supports significantly different features that warrant a new driver. The descriptor format is (just like the ixgbe driver) different. The device can use multiple MSI-X vectors and multiple queues for both send and receive. This allows us to optimize some of the driver code specifically as well compared to the e1000-supported devices. This version of the igb driver no lnger uses fake netdevices and incorporates napi_struct members for each ring to do the multi- queue polling. multi-queue is enabled by default and the driver supports NAPI mode only. All the namespace collisions should be gone in this version too. The register macro's have been condensed to improve readability.
