[PATCH 0/20] dma_ops for i386

[PATCH 0/20] dma_ops for i386

[Glauber Costa]

Hello,

Here there is a series of 20 patches that lays the foundations for
using dma_ops in i386 in the very same way x86_64, as well as many other
architectures already do.

The functions themselves for i386 are placed in a pci-base_32.c, but just
a few among them are actually implemented. Most were no-ops anyway.

Also, as I said, this is by no means a complete coverage of dma_ops.
there are still some call sites to be patches in pci-dma_32.c (although I don't
really plan to change them, but to integrate them in a single pci-dma.c).
I intend to have it done progressively.

The granularity is per-operation, meaning each patch moves one specific function
to the common header. This is compiled-tested in both i386 and x86_64 in 
~5 randconfigs each, and boot-tested in my hardware with my default configs

The motivation for that is the ongoing work for pci-passthrough in KVM.
So ingo, avi, what do you think it's the best way to handle these patches through?

Thanks

[PATCH 02/20] x86: implement dma_map_single through dma_ops

[Glauber Costa]

That's already the name of the game for x86_64. For i386,
we add a pci-base_32.c, that will hold the default operations.
The function call itself goes through dma-mapping.h , the common
header

[PATCH 15/20] x86: move dma_supported and dma_set_mask to pci-dma_32.c

This is the way x86_64 does, so this make them equal. They have
to be extern now in the header, and the extern definition is moved to
the common dma-mapping.h header

[Glauber Costa]

We provide a map_error function in pci-base_32.c to make
sure i386 keeps with the same behaviour it used to.

looks very nice to me! I've applied it to x86.git, lets see what 
happens.

please update the comment too. (just add a delta patch to your next

I see the headers are unified, but the .c files are duplicated.  I 
presume unifying the implementation is deferred to later patches?

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

Houston, we've got a problem! :-/

randconfig testing found that this patchset broke sendfile on certain 
.config's - DMA started returning all 0xfffffffff data, corrupting 
files. (config attached)

After some bisection fun it turns out that the conversions from struct 
page are wrong:

+static inline dma_addr_t dma_map_page(struct device *dev, struct page *page,
+                                     size_t offset, size_t size,
+                                     int direction)
+{
+       return dma_map_single(dev, page_address(page)+offset, size, direction);

because page_address() is not defined for highmem pages in general. (and 
even if it's defined, it will corrupt data)

changing it to page_to_phys() is not good because it goes via a 32-bit 
bottleneck that trims things on PAE:

       dma_addr_t      (*map_single)(struct device *hwdev, void *ptr,

the 'ptr' is 32-bit albeit it's a DMA target.

what i came up is the prototype 32-bit fix below - this works on 32-bit 
but breaks 64-bit because we pass in physical addresses instead of 
virtual direct addresses.

i'll fix the 64-bit side but that means materially touching all the 
dma_mapping_ops instantiations materially on the 64-bit side - not 
really something we wanted to do :-/

Houston, we've got a problem! :-/

randconfig testing found that this patchset broke sendfile on certain 
.config's - DMA started returning all 0xfffffffff data, corrupting 
files. (config attached)

After some bisection fun it turns out that the conversions from struct 
page are wrong:

+static inline dma_addr_t dma_map_page(struct device *dev, struct page *page,
+                                     size_t offset, size_t size,
+                                     int direction)
+{
+       return dma_map_single(dev, page_address(page)+offset, size, direction);

because page_address() is not defined for highmem pages in general. (and 
even if it's defined, it will corrupt data)

changing it to page_to_phys() is not good because it goes via a 32-bit 
bottleneck that trims things on PAE:

       dma_addr_t      (*map_single)(struct device *hwdev, void *ptr,

the 'ptr' is 32-bit albeit it's a DMA target.

what i came up is the prototype 32-bit fix below - this works on 32-bit 
but breaks 64-bit because we pass in physical addresses instead of 
virtual direct addresses.

i'll fix the 64-bit side but that means materially touching all the 
dma_mapping_ops instantiations materially on the 64-bit side - not 
really something we wanted to do :-/

	Ingo

It looks all good to me.
I'll give a shot in my systems to see if it goes okay.

Thanks; Please also see Stephen Tweedie's tree at

I guess your work would be overlapped anyway, but just to make sure there's no 
double work.

This breaks for me with:

ERROR: "dma_supported" [drivers/ssb/ssb.ko] undefined!

They just need to be exported like on x86_64.

Cheers,

Subject: [PATCH] x86: export dma_supported() and dma_set_mask() on i386

dma_supported() and dma_set_mask() were previously inlined,
but are now moved to pci-dma_32.c.

Since they're used by various drivers, they need to be
exported.
