Hi Guenter,
What does the "e-mail is not signed" mean? I try to search some

 How detailed content shold a summary have? I indeed have made some

 About why I didn't send a copy to Linus. Because the document

 If no maintainer is listed, or the maintainer does not respond, send

 Your e-mail is not signed. You don't even have a pgp key as far as
 I can see, at least not one associated with your e-mail address.
 How do you expect anyone to establish your identity ?

 In addition to that, the tag in your repository is not signed and
 does not contain a summary of your changes. Your patches do not
 have a Signed-off-by: tag. The pull message below appears to be
 hand-edited and does not match an auto-generated pull request
 (which should have given you a hint that the commit logs have
 a problem).

 You did not even copy Linus on this e-mail. Do you really think
 he would even notice your pull request, much less apply it ?

Re: [PATCH] Remove support for score architecture

2013-09-02 Thread Lennox Wu
Before we start the development of the S+core, Sunplus had licensed
ARM and MIPS. We develop S+core for other reason such as the price.
Some products on the web of Sunplus adopt S+core , for example
the SPV7050.(http://w3.sunplus.com/products/spv7050.asp) These products
could still be bought from the market. Some high-end products adopt
ARM or MIPS. So, there is no conflict for a company adopts multiple
architectures.

As I said, we recognize that we rarely update because of the limited
applications and rare requests from customers. Maybe we don’t
understand the culture enough; we think that it is unnecessary if we
have no new bugs or new functions, the thought seems wrong. We can
commit some patches in the near future.

Lennox

Re: [PATCH] Remove support for score architecture

2013-09-02 Thread Lennox Wu
Before we start the development of the S+core, Sunplus had licensed
ARM and MIPS. We develop S+core for other reason such as the price.
Some products on the web of Sunplus adopt S+core , for example
the SPV7050.(http://w3.sunplus.com/products/spv7050.asp) These products
could still be bought from the market. Some high-end products adopt
ARM or MIPS. So, there is no conflict for a company adopts multiple
architectures.

As I said, we recognize that we rarely update because of the limited
applications and rare requests from customers. Maybe we don’t
understand the culture enough; we think that it is unnecessary if we
have no new bugs or new functions, the thought seems wrong. We can
commit some patches in the near future.

Best,
Lennox

 Dear all,

 Indeed, Sunplus S+core is not a popular architecture and there is no
 standalone to be sold so you should not find related news on the
 Internet.  However, the s+core is adopted by our SoCs and these SoCs
 are indeed adopted by some companies, we hope the architecture can be
 reserved to provide the more and more powerful Linux for our
 customers. It is true that we rarely update the code because that we
 are rarely requested to add new functions and to correct bugs by our
 customers, and it is also because we have no new product to release.
 In the near future, we will release some patches for the existed
 S+core architecture.


 Key question is not if the platform is popular, but if it is maintained.
 The commit log over the last two years strongly suggests that this is
 not the case. I suspect that the code is far from compilable at this point,
 much less executable. Unfortunately this is hard to verify, as a pre-built
 or even buildable toolchain is not easily available.

 From a company perspective, you might want to decide if you want to put
 resources into this architecture to keep it alive, or focus on more recent
 chips and architectures. Information available on the internet suggests
 that Suncore's more recent chips are based on ARM. Given that, it appears
 somewhat unlikely that resources for maintaining S+core will be made
 available. Guess we'll see if the situation changes.

 The web site associated with the score architecture in MAINTAINERS
 is non-functional and available for sale. The last Ack from one
 of the maintainers was in December 2012. The main maintainer's last
 commit was in 2011. The last maintainer pull request was early 2011.

 More housekeeping.

 Maybe this removal request is a bit early, but architecture support seems
 to have vanished entirely. At the very least this puts interested parties
 (if there are any) on notice.
