Currently the driver returns full length of the active descriptor which is
wrong. We have to go throught the active descriptor and substract the length of
each sent children in the chain from the total length along with the actual
data in the DMA channel registers.
The cyclic case is not handled
The patch series is targeted for getting proper residue value.
Since v3:
- split dwc_get_residue() from dwc_tx_status and improve locking there
- patch 1/4 "dw_dmac: remove unnecessary tx_list field in dw_dma_chan" was
amended a bit to simplify patch 4/4
Since v2:
- get rid of
By this new field we distinguish a total length of the chain and the individual
length of each descriptor in the chain.

On linux, the pages used by kernel could not be migrated. As a result,
if a memory range is used by kernel, it cannot be hot-removed. So if
we want to hot-remove memory, we should prevent kernel from using it.
The way now used to prevent this is specify a memory range by
movablemem_map boot
We now provide an option for users who don't want to specify physical
memory address in kernel commandline.
/*
* For movablemem_map=acpi:
*
* SRAT:|_| |_| |_| |_| ..
* node id:0 1
Here, we do two things:
1) patch1 ~ patch2: Prevent memblock from allocating memory in memory
to be set as ZONE_MOVABLE.
2) patch3: Provide movablemem_map=acpi option for users who
don't want to specify physical address in kernel
Hi Jacob,
I will apply this patch to libpfm4.
But I have a question. Why aren't the other uncore
events included here as well? I am talking about
the events listed in BKDG sections 3.16.2 to 3.16.6?
Are those NOT supported by your kernel patchset?
On Thu, Jan 24, 2013 at 11:06 PM, Jacob Shin
When implementing movablemem_map boot option, we introduced an array
movablemem_map.map[] to store the memory ranges to be set as ZONE_MOVABLE.
Since ZONE_MOVABLE is the latst zone of a node, if user didn't specify
the whole node memory range, we need to extend it to the node end so that
we can

As Michael mentioned, set affinity and select queue will not work very
well when CPU IDs are not consecutive, this can happen with hot unplug.
Fix this bug by traversal the online CPUs, and create a per cpu variable

rename() will change dentry->d_name. The result of this race can

If rtsx_pci_sdmmc is not probed, function pointer pcr->slots[].card_event

If rtsx_pci_sdmmc is not probed, function pointer pcr-slots[].card_event
will point to NULL, and thus rtsx_pci_card_detect will reference a NULL pointer.
Check card_event pointer before referencing it can avoid kernel panic.

rename() will change dentry-d_name. The result of this race can
be worse than seeing partially rewritten name, but we might access
a stale pointer because rename() will re-allocate memory to hold
a longer name.
It's safe in the protection of dentry-d_lock.

As Michael mentioned, set affinity and select queue will not work very
well when CPU IDs are not consecutive, this can happen with hot unplug.
Fix this bug by traversal the online CPUs, and create a per cpu variable
to find the mapping from CPU to the preferable virtual-queue.
Cc: Rusty Russell
Add a cpu notifier to virtio-net, so that we can reset the
virtqueue affinity if the cpu hotplug happens. It improve
the performance through enabling or disabling the virtqueue
affinity after doing cpu hotplug.

An issue has been reported where the PMIC either locks up or fails to

The failure case is where this unwanted write transfers

The DAC found on the last chip select requires a word length of 12 bits,

BTW, isn't this a similar to what should happen with the block io cgroup?
What is the behavior with a fd writing to a file in the scenario you
describe above?
It forbids task moving in this case:
