2007-05-05[TG3]: Add TG3_FLAG_SUPPORT_MSI flag.Michael Chan
And fix up the code to always allow MSI on 5714 A2. Call tg3_find_peer() earlier because we need that information before we can determine whether we can set TG3_FLAG_SUPPORT_MSI or not. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-05-05[TG3]: Eliminate the TG3_FLAG_5701_REG_WRITE_BUG flag.Matt Carlson
This patch removes the use of the TG3_FLAG_5701_REG_WRITE_BUG flag. It's logic is only used to set a function pointer and thus the logic can be collapsed and the flag removed.

2007-05-05[TG3]: Remove reset during MAC address changes.Michael Chan
The reset was added a while back so that ASF could re-init whatever MAC address it wanted to use after the MAC address was changed. Instead of resetting, we can just keep MAC address 1 unchanged during MAC address changes if MAC address 1 is different from MAC address 0. This fixes 2 problems: 1. Bonding calls set_mac_address in contexts that cannot sleep. It no longer sleeps with the chip reset removed. 2. When ASF shares the same MAC address as the NIC, it needs to always do that even when the MAC address is changed. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

2007-05-05[TG3]: Improve NVRAM sizing.Matt Carlson
This patch changes the NVRAM sizing procedure so that the driver can take advantage of devices with 1:1 NVRAM strapping configurations. This is useful in cases where the traditional NVRAM sizing method fails. In the event that the flash size cannot be determined, the largest known NVRAM size is used. The patch also removes support for 5755 NVRAM devices that are not supported by Broadcom and adds explicit sizing for this device.

2007-05-05[TG3]: Fix TSO bugs.Matt Carlson
1. Remove the check for skb->len greater than MTU when doing TSO. When the destination has a smaller MSS than the source, a TSO packet may be smaller than the MTU and we still need to process it as a TSO packet. 2. On 5705A3 devices with TSO enabled, the DMA engine can hang due to a hardware bug. This patch avoids the hanging condition by reducing the DMA burst size.

2007-05-04iomap: make the default iomap functions fail softerLinus Torvalds
We used to BUG_ON() for a badly mapped IO port, which is certainly correct, but actually made it harder to debug the case where the ATA drivers had incorrectly mapped a nonconnected ATA port. So make badly mapped ports trigger a WARN_ON(), and throw the IO away instead (and return all ones for reads). For things like broken driver initialization - which is the most likely cause anyway - that should mean that the machine comes up and is usable (at least that was the case for the ATA breakage that triggered this patch). It tends to be a whole lot easier to do a "dmesg" on a working machine than to try to capture logs off a dead one. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Fix a race condition in the transmit code, where the dma interrupt could update the free tx buffer count concurrently and wedge the tx queue. Fix the misuse of the rx frame status and rx frame length registers: no more "fifo overrun" errors caused by the OFLOW bit being tested in the frame length register (instead of the status register), and no more missed packets due to incorrect length taken from status register (instead of the frame length register). Fix a panic (skb_over_panic BUG) caused by allocating and then copying an incoming packet while the packet length register was changing. Cut-and-paste the reset code from the powermac mace driver (mace.c), so the NIC functions when MacOS does not initialise it (important for anyone wanting to use the Emile boot loader). Cut-and-paste the error counting and timeout recovery code from mace.c. Fix over allocation of rx buffer memory (it's page order, not page count). Converted to driver model. Converted to DMA API.

2007-05-04CUDA ADB fixesFinn Thain
Fix the flakiness in the CUDA ADB driver on m68k macs (keypresses getting wedged down or ADB just going AWOL altogether). The only IRQ used by this driver is the VIA shift register IRQ. The PowerMac conditional code disables the other VIA IRQ sources, so don't mess with the other IRQ flags in the common code -- m68k macs need them. When polling, don't disable local interrupts when we only need to disable the CUDA interrupt. Unless polling, don't clear the shift register IRQ flag. On m68k macs this creates a race that often breaks CUDA ADB. Tested on Quadra 840av and LC630 (both m68k); also Beige G3 (powerpc).

2007-05-04m68k: Mac II ADB fixesFinn Thain
Fix a crash caused by requests placed in the queue with the completed flag already set. This lead to some ADB_SYNC requests returning early and their request structs being popped off the stack while still queued. Stack corruption ensued or an invalid request callback pointer was invoked or both. Eliminate macii_retransmit() and its buggy implementation of macii_write(). Have macii_queue_poll() fully initialise the request queues. Fix a bug in macii_queue_poll() where the last_req pointer was not being set. This caused some requests to leave the queue before being completed (and would also corrupt the stack under certain conditions). Fix a race in macii_start that could set the state machine to "reading" while current_req was null. No longer send poll commands with the ADBREQ_REPLY flag -- doing that caused the replies to be stored in the request buffer where they were forgotten about. Don't autopoll by continuously sending new Talk commands. Get the controller to do that for us. This reduces the ADB interrupt rate on an idle bus to about 5 per second. Only autopoll the devices that were probed. Explicitly clear the interrupt flag when polling. Use disable_irq rather than local_irq_save when polling. Remove excess local_irq_save/restore pairs. Improve bus timeout and service request detection. Remove unused code (last_reply, adb_dir etc) and unneeded code (prefix_len, first_byte etc). Change TIP and TACK to their correct names on this ADB controller (ST_EVEN and ST_ODD). Add some commentry. Add a generous quantity of sanity checks (BUG_ONs).

2007-05-04m68k: Mac nubus IRQ fixes (plan E)Finn Thain
Some Macs lack a slot interrupt enable register. So the existing code makes disabled and unregistered slot IRQ lines outputs set high. This seems to work on quadras, but does not work on genuine VIAs (perhaps the card still succeeds in pulling the line low, or perhaps because this increases the settle time on the port A input, meaning that the CA1 IRQ could fire before the slot line reads active). Because of this, the nubus_active flags were used to mask IRQs, which is actually worse than the problem it tries to solve. Any interrupt masked by nubus_active will remain asserted and prevent further transitions on CA1. And so the nubus gets wedged regardless of hardware (emulated VIA ASIC, real VIA chip or RBV). The best solution to this hardware limitation of genuine VIAs is to disable the umbrella SLOTS IRQ when disabling a slot on those machines. Unfortunately, this means all slot IRQs get disabled when any slot IRQ is disabled. But it is only a problem when there's more than 1 device using nubus interrupts. Another potential problem for genuine VIAs is an unregistered nubus IRQ. Eventually it will be possible to enable the CA1 interrupt by installing its handler only _after_ all nubus drivers have loaded but _before_ the kernel needs them, at which time this last problem can be fixed. For now it can be worked around: - disable MacOS extensions - don't boot MacOS (use the Emile bootloader instead) - get the bootloaders to disable ROM drivers (Penguin does this for video cards already, don't know about Emile) - physically remove unsupported cards Signed-off-by: Finn Thain <fthain@telegraphics.com.au> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-05-04m68k: Mac IRQ prepFinn Thain
Make sure that there are no slot IRQs asserted before leaving the nubus handler. If there are and we don't then the nubus gets wedged because this prevents a CA1 transition, which means no more nubus IRQs. Make the interrupt dispatch loops terminate sooner. Explicitly initialise the VIA latches to make the code more easily understood. Also some cleanups.
