Tizen 1.0 Larkspur SDK and Source Code Release
Tizen was formed from the MeeGo and LiMo projects to create mobile devices such as smartphones and tablets. The project has announced the 1.0 release of its Software Development Kit (SDK) and the platform source code. The release notes for the SDK and the source code contain the details.
3.4-rc4 (22.04)
^^^^^^^^^^^^^^^
The 3.4 development cycle continues with the release of the 3.4-rc4 prepatch. Linus says: "But none of it really looks all that scary. It looks like the 3.4 release is all on track, but please do holler if you see regressions." There are some reports of ongoing difficulties with the Nouveau graphics driver; hopefully those will be sorted out soon.
3.4-rc5 (29.04)
^^^^^^^^^^^^^^^
The fifth 3.4 prepatch is out. "And like -rc4, quite a bit of the changes came in on Friday (with some more coming in yesterday). And we haven't been calming down, quite the reverse. -rc5 has almost 50% more commits than -rc4 had. Not good." That said, what's going in is mostly fixes; see the announcement for the short-form changelog.

3.4-rc3, released on April 15.
"Anyway, the shortlog is appended, but I don't think there really is anything
hugely exciting there. It's mostly driver updates, with a smattering of
architecture fixes and networking." All told, 332 changesets have been merged
since 3.4-rc2.

^^^^^^^^^^^
More than eight years after the 2.6.0 release, Willy Tarreau has announced that
he will no longer be releasing updates to the 2.4 series.
For those who really are unable to move on, he may maintain a git tree with an
occasional fix, "but with no guarantees."

3.4-rc2 (released on April, 7th)
^^^^^^^
- The x32 system call ABI
(https://sites.google.com/site/x32abi/documents/abi.pdf?attredirects=0&d=1)
- printk: support structured and multi-facility log messages
(lwn.net/Articles/490690/)
- The Common Clk Framework (see drivers/clk/clk-*.c for examples)
- Introduce a led trigger for CPU activity and consolidate LED driver in ARM
(lwn.net/Articles/489612/)
<< INSERT SLIDES ABOUT struct device >>
- Reworking the DMA mapping code Patchset
* merge ARM DMA API in generic DMA code
* remove duplicated code
* remove special alloc/mapping functions for writecombine, (non)coherent
* use flags in dma_(alloc/mapping) for writecombine, (non)coherent
* now each architecture can implement the following functions:
include/linux/dma-mapping.h (very simplified pseudo code):
struct dma_map_ops {
vaddr = alloc(dev, size, &paddr, attr)
free(dev, size, vaddr, paddr, attr)
vaddr = mmap(dev, paddr, attr)
sync_for_cpu (dev, paddr)
sync_for_device (dev, vaddr)
...
yes/no = dma_supported(dev)
};
e.g. arm does this in arch/arm/common/dmabounce.c
* add per-device i/o mmu support to (ARM) DMA API:
Some hardware has a separate IOMMU built into it that cannot be used
for other devices, so the IOMMU cannot be made available to the system
as a whole.
But it is possible to attach a device-specific dma_map_ops structure
to such devices that would cause the DMA API to use the IOMMU without
the device driver even needing to know about it.
arch/arm/include/asm/dma-iommu.h:
struct dma_iommu_mapping {
/* iommu specific data */
struct iommu_domain *domain;
void *bitmap;
size_t bits;
unsigned int order;
dma_addr_t base;
spinlock_t lock;
struct kref kref;
};
struct dma_iommu_mapping *arm_iommu_create_mapping(dma_addr_t base,
size_t size, int order);
void arm_iommu_release_mapping(struct dma_iommu_mapping *mapping);
int arm_iommu_attach_device(struct device *dev,
struct dma_iommu_mapping *mapping);
(implementation see below)
arch/arm/mm/dma-mapping.c:
struct dma_map_ops iommu_ops = {
.alloc = arm_iommu_alloc_attrs,
.free = arm_iommu_free_attrs,
.mmap = arm_iommu_mmap_attrs,
.map_page = arm_iommu_map_page,
.unmap_page = arm_iommu_unmap_page,
.sync_single_for_cpu = arm_iommu_sync_single_for_cpu,
.sync_single_for_device = arm_iommu_sync_single_for_device,
.map_sg = arm_iommu_map_sg,
.unmap_sg = arm_iommu_unmap_sg,
.sync_sg_for_cpu = arm_iommu_sync_sg_for_cpu,
.sync_sg_for_device = arm_iommu_sync_sg_for_device,
};
int arm_iommu_attach_device(struct device *dev,
struct dma_iommu_mapping *mapping)
{
int err;
err = iommu_attach_device(mapping->domain, dev);
if (err)
return err;
kref_get(&mapping->kref);
dev->archdata.mapping = mapping;
set_dma_ops(dev, &iommu_ops);
printk(KERN_INFO "Attached IOMMU controller to %s device.\n",
dev_name(dev));
return 0;
}
Prior to this work, IOMMU awareness had been built into specific drivers
directly.
Status of Android merge:
^^^^^^^^^^^^^^^^^^^^^^^^
Grant Likely asked about the progress of the Android patches into the mainline;
when is that job "done"?
Once Android is using mainline kernels was the answer Bottomley gave.
Kroah-Hartman noted that the real problem is on the user-space side.
Kernel hackers can't do anything about changing the Android user space,
but companies like Linaro and Samsung are making some progress in doing so.
The 3.3 kernel can boot an Android user space, but it will
"eat your battery alive",
he said. We are making progress, but it will require teamwork to get there.
Plumbers:
^^^^^^^^^
Udev and systemd to merge
Zawinski's Law.
Quick, someone write an email reader for systemd, to stop the progression before
it's too late. ;-)
