ToPIC95 brides (and maybe some other too) require to use the ExCA registers
to power up the socket if a 16bit card is pluged. allow socket drivers to
set a flag so that yenta does just that. also clean up yenta_get_status()
a bit to use the new yenta_get_power() function.
Side note: ToPIC97 bridges (at least in Rev.5 i have) don't require this.
Ryan Underwood <nemesis-lists@icequake.net> said:
According to the mail that David Hinds received from a Toshiba engineer,
ToPIC95 and 97 do require this, and ToPIC100 does not. Maybe you have a
later revision.
For all chips, 16-bit cards can be enabled through ExCA. So doesn't it
make sense just to make this the default behavior for all Toshiba chips,
to avoid corner cases showing up later?
Daniel responded:
I disagree with ryan to change anything for topic97 bridges. they work.
and I couldn't find (read google) any report of a topic97 breaking on
applying power with the CB registers.
I'm having several toshba notebooks at work (and home) with topic95,97,100
bridges. Only the ones with a topic95 didn't work.

This patch adds a new kernel debug feature: CONFIG_DETECT_SOFTLOCKUP.
When enabled then per-CPU watchdog threads are started, which try to run
once per second. If they get delayed for more than 10 seconds then a
callback from the timer interrupt detects this condition and prints out a
warning message and a stack dump (once per lockup incident). The feature
is otherwise non-intrusive, it doesnt try to unlock the box in any way, it
only gets the debug info out, automatically, and on all CPUs affected by
the lockup.

When handling writes to /proc/irq, current code is re-programming rte
entries directly. This is not recommended and could potentially cause
chipset's to lockup, or cause missing interrupts.
CONFIG_IRQ_BALANCE does this correctly, where it re-programs only when the
interrupt is pending. The same needs to be done for /proc/irq handling as well.
Otherwise user space irq balancers are really not doing the right thing.
- Changed pending_irq_balance_cpumask to pending_irq_migrate_cpumask for
lack of a generic name.
- added move_irq out of IRQ_BALANCE, and added this same to X86_64
- Added new proc handler for write, so we can do deferred write at irq
handling time.
- Display of /proc/irq/XX/smp_affinity used to display CPU_MASKALL, instead
it now shows only active cpu masks, or exactly what was set.
- Provided a common move_irq implementation, instead of duplicating
when using generic irq framework.
Tested on i386/x86_64 and ia64 with CONFIG_PCI_MSI turned on and off.
Tested UP builds as well.
MSI testing: tbd: I have cards, need to look for a x-over cable, although I
did test an earlier version of this patch. Will test in a couple days.

Yet another architecture not coverd by GEN_RTC - sparc64 never picked
it until now and it doesn't have asm/rtc.h to go with it, so it
wouldn't compile anyway (or have these ioctls in the user-visible
headers, for that matter).
FWIW, I'm very tempted to introduce ARCH_HAS_GEN_RTC and have it set
in arch/*/Kconfig for architectures that know what to do with this
stuff - for something supposedly generic the list of architectures
where it doesn't work is getting too long...

Use the status tag to determine if there are new events in
tg3_interrupt_tagged(). We discussed about this a while ago with Grant
Grundler and DaveM. This scheme makes it unnecessary to clear the
updated bit in the status block when using tagged mode, and only
a simple comparison is needed to determine if there are new events.
The tp->lock around netif_rx_complete() and tg3_restart_ints() is also
removed. It is unnecessary with DaveM's new locking scheme.

Remove unnecessary status block accesses in tg3_msi(). Since MSI is
not shared, it is unnecessary to read the status block to determine if
there are any new events in the MSI handler. It is also unnecessary to
clear the updated bit in the status block.
Since the poll list is per-cpu, tg3_poll() will be scheduled to run on
the same CPU that received the MSI. Prefetches for the status block
and the next rx descriptors are added in tg3_msi() to improve their
access times when tg3_poll() runs.
In the non-MSI irq handlers, we need to check the status block because
interrupts may be shared. Only prefetches for the next rx descriptors
are added.
