[U-Boot] [PATCH 0/2] make u-boot/drivers/net/designware cache supportive

[U-Boot] [PATCH 0/2] make u-boot/drivers/net/designware cache supportive

[Frank Dols]

Hello Vipin,
As discussed, see included the patches to make your
u-boot/drivers/net/designware Ethernet device driver cache support aware.
First patch is about: do an explicit memory access instead of implicit,
I re-written assignments to use readl() and writel().
Second patch is about: making the driver able to work in a cached environment
(do I$/D$ flush/invalidate where necessary).

Frank Dols (2):
  drivers/net/designware, do an explicit memory access instead of
    implicit,     re-written assignments to use readl() and writel(),  
      all of this as preperation for making the driver able to work in
    a cached environment (I$D$ support).
  u-boot/drivers/net/designware with cache support.

You dont need to write u-boot/drivers in the patch subject. It is anyway 
implicit :)

Provide a short patch title and a longer description in the patch 
itself. that would be much more readable

My first feeling is that the descriptors are allocated as Normal 
Cachabale memory and it would not help to access them using readl/writel

Should the desciptors be allocated as non-cachable memory. If yes then 
how to do that in u-boot

I suppose the rest of the code would be better reviewed if we know about 
this

[U-Boot] [PATCH 1/2] drivers/net/designware, do an explicit memory access instead of implicit, re-written assignments to use readl() and writel(), all of this as preperation for making the driver able to work in a cached environment (I$D$ support).

I would say that yes, descriptors are allocated in DRAM, so they are
cacheable.

And no, we don't need to allocate them non-cacheable, although in this
case we need to use cache flush and invalidate calls. I would suggest
doing so rather than allocating the descriptors non cacheable, because
using non-cacheable memory makes the dependency between the driver and
cache codes implicit (and thus more prone to improperly thought out
changes in either code) and the memory usage more complex, while
explicit cache operations make the relationship explicit.

One can always not cache descriptors if you one wants to, without this
decision breaking driver functionality.

Amicalement,

Yes, got it. Thanks Albert

Frank, so in that case rather changing the code to use readl/writel, 
cache flush and invalidate operations need to be performed at 
appropriate places

I believe patch 2/2 adds explicit cache ops, though I haven't read it in
detail and thus don't know if everything needed is present and ok.

Hi Vipin and Albert,
Sorry, I have to clarify here a bit more.
The descriptors are 16 bytes in length and a cache line is in most architectures more than 16 bytes in length (in our case either 32 or 64).
This means that cached accesses is not an option for these descriptors. Background, two adjacent descriptors as be on one cache line may be owned by different entities (host cpu / network ip).
Explicit cache calls that we are added in patch 2/2 are meant for payload of the package. And these are made cache line aligned with patch 1/2.
Unfortunately we can't align the descriptors on cache line boundaries due to hardware limitations (for architectures with cache line longer than 16 bytes) !
With kind regards, greetings, Frank.

There is no reason to remove the list. This is not  noise I believe. 
Infact by including the list, you are intimating other developers that such work would be available soon

Albert, do you think any different.

Yes, this is a problem and I can't think of a clean solution. Specially because u-boot (as of today) does not support non-cached memory

Albert?

Yes, that is what I thought

Yes, I know that. The descriptors are 16 bytes and they need to be contiguous in memory

PS: I have not added the list but I strongly feel that this mail should also go to the uboot list

Do you plan to re submit with the subject of patch 1 fixed and the

Yes, this is appropriate for the list.

I attempted to apply these 2 patches (and fix your improper commit
message... please see http://www.denx.de/wiki/U-Boot/Patches ), but
your change causes build errors and warnings even then.

Please address these issues and resubmit.

Thanks,
