ieee1394: rawiso: requeue packet for transmission after skipped cycle

As it seems, some host controllers have issues that can cause them to
skip cycles now and then when using large packets. I suspect that this
is due to DMA not succeeding in time. If the transmit fifo can't contain
more than one packet (big packets), the DMA should provide a new packet
each cycle (125us). I am under the impression that my current PCI
express test system can't guarantee this.

In any case, the patch tries to provide a workaround as follows:
The DMA program descriptors are modified such that when an error occurs,
the DMA engine retries the descriptor the next cycle instead of
stalling. This way no data is lost. The side effect of this is that
packets are sent with one cycle delay. This however might not be that
much of a problem for certain protocols (e.g. AM824). If they use
padding packets for e.g. rate matching they can drop one of those to
resync the streams.

The amount of skips between two userspace wakeups is counted. This
number is then propagated to userspace through the upper 16 bits of the
'dropped' parameter. This allows unmodified userspace applications due
to the following:
1) libraw simply passes this dropped parameter to the user application
2) the meaning of the dropped parameter is: if it's nonzero, something
bad has happened. The actual value of the parameter at this moment does
not have a specific meaning.

A libraw client can then retrieve the number of skipped cycles and
account for them if needed.

firewire: fw-ohci: work around generation bug in TI controllers (fix AV/C and more)

Unlike the ohci1394 driver, fw-ohci uses the selfIDGeneration field of
bus reset packets to determine the generation of incoming requests as
per OHCI 1.1 clause 8.4.2.3.  This is more precise --- provided that the
controller inserts the correct generation.  Texas Instruments chips
often don't.

This prevented the transmission of response packets, which for example
broke AV/C transactions as used when communicating with miniDV cameras
and any other AV/C devices.

There is apparently no way to detect and adjust incorrect generations.
Therefore we ignore the generation of bus reset packets from TI chips
and use the generation of the self ID buffer instead.  Alas this is
received at a slightly wrong time.  In rare cases, this could cause us
to not respond to legitimate requests or to respond to expired requests.
(The latter is less likely because the bus reset packet AR event is
typically handled before the self ID complete event.)

Bug reported by Mladen Kuntner, who was extraordinarily patient while
dealing with the driver maintainers.  Fix confirmed to be required and

16 years agomm: sparsemem memory_present() fix
Ingo Molnar [Tue, 15 Apr 2008 23:40:00 +0000 (01:40 +0200)]
mm: sparsemem memory_present() fix

Fix memory corruption and crash on 32-bit x86 systems.

If a !PAE x86 kernel is booted on a 32-bit system with more than 4GB of
RAM, then we call memory_present() with a start/end that goes outside
the scope of MAX_PHYSMEM_BITS.

That causes this loop to happily walk over the limit of the sparse
memory section map:

    for (pfn = start; pfn < end; pfn += PAGES_PER_SECTION) {
                unsigned long section = pfn_to_section_nr(pfn);
                struct mem_section *ms;

                sparse_index_init(section, nid);
                set_section_nid(section, nid);

                ms = __nr_to_section(section);
                if (!ms->section_mem_map)
                        ms->section_mem_map = sparse_encode_early_nid(nid) |
                                SECTION_MARKED_PRESENT;

'ms' will be out of bounds and we'll corrupt a small amount of memory by
encoding the node ID and writing SECTION_MARKED_PRESENT (==0x1) over it.

The corruption might happen when encoding a non-zero node ID, or due to
the SECTION_MARKED_PRESENT which is 0x1:

mmzone.h:#define SECTION_MARKED_PRESENT (1UL<<0)

The fix is to sanity check anything the architecture passes to
sparsemem.

This bug seems to be rather old (as old as sparsemem support itself),
but the exact incarnation depended on random details like configs, which
made this bug more prominent in v2.6.25-to-be.

An additional enhancement might be to print a warning about ignored or
trimmed memory ranges.
