- uv_ratio : allow a ratio of saturation between u and v. If you
have a ratio of 40 and a saturation of 100, usat will be 80 and
vstat 120. Useful to correct a bad color balance.
- full_luma_range : provide a better contrast in using the full

[PATCH] ext3: reduce allocate-with-reservation lock latencies
Currently in ext3 block reservation code, the global filesystem reservation
tree lock (rsv_block) is hold during the process of searching for a space
to make a new reservation window, including while scaning the block bitmap
to verify if the avalible window has a free block. Holding the lock during
bitmap scan is unnecessary and could possibly cause scalability issue and
latency issues.
This patch tries to address this by dropping the lock before scan the
bitmap. Before that we need to reserve the open window in case someone
else is targetting at the same window. Question was should we reserve the
whole free reservable space or just the window size we need. Reserve the
whole free reservable space will possibly force other threads which
intended to do block allocation nearby move to another block group(cause
bad layout). In this patch, we just reserve the desired size before drop
the lock and scan the block bitmap. This patch fixed a ext3 reservation
latency issue seen on a cvs check out test. Patch is tested with many fsx,
tiobench, dbench and untar a kernel test.

retake the lock and retry the merge mechanism after allocating a new request.
Instead assume that the chance of a merge remains slim, and now that we've
done most of the work allocating a request we may as well just go with it.
Also be rid of the GFP_ATOMIC allocation: we've got working mempools for the
block layer now, so let's save atomic memory for things like networking.

[PATCH] ll_rw_blk: prevent huge request allocations
Currently we cap request allocations at q->nr_requests, but we allow a
batching io context to allocate up to 32 more (default setting). This
can flood the queue with request allocations, with only a few batching
processes. The real fix would be to limit the number of batchers, but
as that isn't currently tracked, I suggest we just cap the maximum
number of allocated requests to eg 50% over the limit.
This was observed in real life, users typically see this as vmstat bo
numbers going off the wall with seconds of no queueing afterwards.
Behaviour this bursty is not beneficial.

[PATCH] PCI: DMA bursting advice
After seeing, at best, "guesses" as to the following kind
of information in several drivers, I decided that we really
need a way for platforms to specifically give advice in this
area for what works best with their PCI controller implementation.
Basically, this new interface gives DMA bursting advice on
PCI. There are three forms of the advice:
1) Burst as much as possible, it is not necessary to end bursts
on some particular boundary for best performance.
2) Burst on some byte count multiple. A DMA burst to some multiple of
number of bytes may be done, but it is important to end the burst
on an exact multiple for best performance.
The best example of this I am aware of are the PPC64 PCI
controllers, where if you end a burst mid-cacheline then
chip has to refetch the data and the IOMMU translations
which hurts performance a lot.
3) Burst on a single byte count multiple. Bursts shall end
exactly on the next multiple boundary for best performance.
Sparc64 and Alpha's PCI controllers operate this way. They
disconnect any device which tries to burst across a cacheline
boundary.
Actually, newer sparc64 PCI controllers do not have this behavior.
That is why the "pdev" is passed into the interface, so I can
add code later to check which PCI controller the system is using
and give advice accordingly.

In our hardware situation, the BIOS is unable to store or generate it's PIRQ

parameter, pirqaddr to allow the bootloader (or BIOS based loader) to inform

[PATCH] Use pci_set_dma_mask() instead of direct assignment of DMA mask
The amd8111e driver directly assigns the DMA mask to the dma_mask
member of the struct pci_dev instead of using pci_set_dma_mask(). This
makes the call to pci_dma_supported() redundant as pci_set_dma_mask()
does this check.

For boards that invert the SMC91x IRQ line (maybe an FPGA inverts it),
the set_irq_type() call can't assume IRQT_RISING. These particular

[PATCH] ACPI-based PCI resources: PCMCIA bugfix, but resources missing in trees
Don't auto-configure yenta sockets for PCMCIA devices if it is connected to
the root PCI bus on the x86 or x86_64 architectures. Previously, this was
handled by the "ioport_resource"/"iomem_resource" check a few lines below,
but with the new ACPI-based resource handling this doesn't catch all cases
any longer.
pci-yenta-cardbus-fix.patch and this patch should solve the initialization
time trouble. However, the ACPI-based PCI resource handling is badly
broken, IMHO:
- many resources of devices don't show up in the resource trees (
/proc/iomem and /proc/ioports) any longer. This means that PCMCIA, but
also possibly other subsystems (ISA, PnP, ...) do not know which resources
it cannot use.
- verify_root_windows() should fail if there are no iomem _or_ ioport
resources, not only if there are no iomem _and_ ioport resources.

[PATCH] pcmcia: 8 and 16 bit access for static_map
The PCMCIA card services layer is never setting the i/o map attributes when
SS_CAP_STATIC_MAP is specified. Net result, sockets' set_io_map() calls
always see requests with most flags clear, meaning 8 bit access.
For hardware that always autosizes, that won't matter; and all current
STATIC_MAP drivers ignore those attributes. A new driver (for at91rm9200)
suffers badly from this, since this forces everything into 8 bit mode and
that breaks both (a) cards requiring 16 bit access, and (b) ide-cs; but of
course 8-bit cards work OK (as does accessing card attributes).
So this patch arranges to pass the attributes down, matching the behavior
for non-static mappings (using the first/only I/O window).
