2006-09-19Revert mmiocfg heuristics and blacklist changesLinus Torvalds
This reverts commits 11012d419cfc0e0f78ca356aca03674217910124 and 40dd2d20f220eda1cd0da8ea3f0f9db8971ba237, which allowed us to use the MMIO accesses for PCI config cycles even without the area being marked reserved in the e820 memory tables. Those changes were needed for EFI-environment Intel macs, but broke some newer Intel 965 boards, so for now it's better to revert to our old 2.6.17 behaviour and at least avoid introducing any new breakage. Andi Kleen has a set of patches that work with both EFI and the broken Intel 965 boards, which will be applied once they get wider testing.

2006-09-19[PATCH] genirq core: fix handle_level_irq()Ingo Molnar
while porting the -rt tree to 2.6.18-rc7 i noticed the following screaming-IRQ scenario on an SMP system: 2274 0Dn.:1 0.001ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.010ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.020ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.029ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.039ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.048ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.058ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.068ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.077ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.087ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.097ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) as it turns out, the bug is caused by handle_level_irq(), which if it races with another CPU already handling this IRQ, it _unmasks_ the IRQ line on the way out. This is not how 2.6.17 works, and we introduced this bug in one of the early genirq cleanups right before it went into -mm. (the bug was not in the genirq patchset for a long time, and we didnt notice the bug due to the lack of -rt rebase to the new genirq code. -rt, and hardirq-preemption in particular opens up such races much wider than anything else.)

This turns out to be a genuine bug. The queue lock and xmit lock are intentionally taken out of order. Two things are supposed to prevent dead-locks from occuring: 1) When we hold the queue_lock we're supposed to only do try_lock on the tx_lock. 2) We always drop the queue_lock after taking the tx_lock and before doing anything else. > > the existing dependency chain (in reverse order) is: > > -> #1 (&dev->_xmit_lock){-+..}: > [<c012e7b6>] lock_acquire+0x76/0xa0 > [<c0336241>] _spin_lock_bh+0x31/0x40 > [<c02d25a9>] dev_activate+0x69/0x120 This path obviously breaks assumption 1) and therefore can lead to ABBA dead-locks. I've looked at the history and there seems to be no reason for the lock to be held at all in dev_watchdog_up. The lock appeared in day one and even there it was unnecessary. In fact, people added __dev_watchdog_up precisely in order to get around the tx lock there. The function dev_watchdog_up is already serialised by rtnl_lock since its only caller dev_activate is always called under it. So here is a simple patch to remove the tx lock from dev_watchdog_up. In 2.6.19 we can eliminate the unnecessary __dev_watchdog_up and replace it with dev_watchdog_up. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
