David Gibson [Tue, 14 Aug 2007 03:52:42 +0000 (13:52 +1000)]
[POWERPC] Fix irq flow handler for 4xx UIC

At present the driver for the UIC (the embedded interrupt controller
in 4xx chips) uses the handle_level_irq() flow handler.  It turns out
this does not correctly handle level triggered interrupts on the UIC.

Specifically, acknowledging an irq on the UIC (i.e. clearing the
relevant bit in UIC_SR) will have no effect for a level interrupt
which is still asserted by the external device, even if the irq is
already masked.  Therefore, unlike handle_level_irq() we must ack the
interrupt after invoking the ISR (which should cause the device to
stop asserting the irq) instead of acking it when we mask it, before
the ISR.

This patch implements this change, in a new handle_uic_irq(), a
customised irq flow handler for the UIC.  For edge triggered
interrupts, handle_uic_irq() still uses the old flow - we must ack
edge triggered interrupt before the ISR not after, or we could miss a
second event which occurred between invoking the ISR and acking the
irq.

[POWERPC] Remove gratuitous reads from maple PCI config space methods

The maple PCI configuration space write methods read the written
location immediately after the write is performed, presumably in order
to flush the write.  However, configuration space writes are not
allowed to be posted, making these reads gratuitous.  Furthermore,
this behavior potentially causes us to violate the PCI PM spec when
changing between e.g. D0 and D3 states, because a delay of up to 10ms
may be required before the OS accesses configuration space after the
write which initiates the transition.  It definitely causes a system
hang for me with a Broadcom 5721 PCIE network adapter, which is fixed
by this change.

Therefore this removes the gratuitous reads from u3_agp_write_config,
u3_ht_write_config, and u4_pcie_write_config.

[POWERPC] Fix small race in 44x tlbie function

The 440 family of processors don't have a tlbie instruction.  So, we
implement TLB invalidates by explicitly searching the TLB with tlbsx.,
then clobbering the relevant entry, if any.  Unfortunately the PID for
the search needs to be stored in the MMUCR register, which is also
used by the TLB miss handler.  Interrupts were enabled in _tlbie(), so
an interrupt between loading the MMUCR and the tlbsx could cause
incorrect search results, and thus a failure to invalide TLB entries
which needed to be invalidated.

This fixes the problem in both arch/ppc and arch/powerpc by inhibiting
interrupts (even critical and debug interrupts) across the relevant

This is part 2 of the patch for bug #245832, part 1 of which is already
in the git tree.

The problem was that sdp->sd_log_num_databuf was not always being
protected by the gfs2_log_lock spinlock, but the sd_log_le_databuf
(which it is supposed to reflect) was protected.  That meant there
was a timing window during which gfs2_log_flush called
databuf_lo_before_commit and the count didn't match what was
really on the linked list in that window.  So when it ran out of
items on the linked list, it decremented total_dbuf from 0 to -1 and
thus never left the "while(total_dbuf)" loop.

The solution is to protect the variable sdp->sd_log_num_databuf so
that the value will always match the contents of the linked list,
and therefore the number will never go negative, and therefore, the
loop will be exited properly.
