forcedeth: fix random hang in forcedeth driver when using netconsole

2007-08-22T23:23:26Z

If the forcedeth driver receives too much work in an interrupt, it assumes it has a broken hardware with stuck IRQ. It works around the problem by disabling interrupts on the nic but makes a printk while holding device spinlog - which isn't smart thing to do if you have netconsole on the same nic. This patch moves the printk's out of the spinlock protected area. Without this patch the machine hangs hard. With this patch everything still works even when there is significant increase on CPU usage while using the nic.

r8169: avoid needless NAPI poll scheduling

2007-08-22T23:23:26Z

Theory : though needless, it should not have hurt. Practice: it does not play nice with DEBUG_SHIRQ + LOCKDEP + UP (see https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=3D242572). The patch makes sense in itself but I should dig why it has an effect on #242572 (assuming that NAPI do not change in a near future). Patch in mainline as 313b0305b5a1e7e0fb39383befbf79558ce68a9c.

sky2: check drop truncated packets

2007-08-22T23:23:25Z

Backport of commit 71749531f2d1954137a1a77422ef4ff29eb102dd If packet larger than MTU is received, the driver uses hardware to truncate the packet. Use the status registers to catch/drop them. Signed-off-by: Stephen Hemminger Signed-off-by: Greg Kroah-Hartman

sky2: check for more work before leaving NAPI

2007-08-22T23:23:25Z

Backport of commit 5c11ce700f77fada15b6264417d72462da4bbb1c This patch avoids generating another IRQ if more packets arrive while in the NAPI poll routine. Before marking device as finished, it rechecks that the status ring is empty. Signed-off-by: Stephen Hemminger Signed-off-by: Greg Kroah-Hartman

sky2: carrier management

2007-08-22T23:23:24Z

backport of commit 55d7b4e6ed6ad3ec5e5e30b3b4515a0a6a53e344 Make sky2 handle carrier similar to other drivers, eliminate some possible races in carrier state transistions. Signed-off-by: Stephen Hemminger Signed-off-by: Greg Kroah-Hartman

sky2: restore workarounds for lost interrupts

2007-08-22T23:23:24Z

Backport of commit c59697e06058fc2361da8cefcfa3de85ac107582 This patch restores a couple of workarounds from 2.6.16: * restart transmit moderation timer in case it expires during IRQ routine * default to having 10 HZ watchdog timer. At this point it more important not to hang than to worry about the power cost. Signed-off-by: Stephen Hemminger Signed-off-by: Greg Kroah-Hartman

potential compiler error, irqfunc caller sites update

2007-07-06T17:23:43Z

In 7d12e780e003f93433d49ce78cfedf4b4c52adc5 David Howells performed this evolution: "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers" He correctly updated many of the function definitions that were using this extra regs pointer parameter but forgot to update some caller sites of those functions. The reason the modifications was not properly done on all drivers is that some drivers were rarely compiled because they are for AMIGA, or that some code sites were inside #ifdefs where the option is not set or inside #if 0. Here is the semantic patch that found the occurences and fixed the problem. @ rule1 @ identifier fn; identifier irq, dev_id; typedef irqreturn_t; @@ static irqreturn_t fn(int irq, void *dev_id) { ... } @@ identifier rule1.fn; expression E1, E2, E3; @@ fn(E1, E2 - ,E3 ) Signed-off-by: Yoann Padioleau Cc: "David S.
