It sounds like you are looking to design a functional model, a module 
that utilizes some type of design spec or standard to verify if the 
design implementation works according to the design-spec/standard, correct?

If true, my first question would be, what document will you be basing 
this module on?

It probably could be useful- the more testing on something the better. 
But I think the first step is you need to define what 
document/spec/standard this module is going to follow, then how this 
module is going to be designed and used, then go from there.

You could consider using John Calixto's CMD passthrough ioctl for this,
and writing your tests in userspace:

  http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=cb87ea28ed9e75a41eb456bfcb547b4e6f10e750

It would be great to include your finished tool in a testsuite, both for
testing card commands and for testing the ioctl functionality itself.  :)

Thanks!

- Chris.

Re: Testing Infrastructure for SD/MMC Commands

[seedshope]

Hi All,

I uses potevio MicroSD 512M to test the SD/MMC driver in current master
kernel. I found some issue:

1. The issue
(1) After I insert the microSD,Why The SD card probe finish(The
parrition and device has already register). But The more and more data
transport between card and host? Who can told me the function of this
data.(The log information as following).

(2) The MicroSD can be probe successful. But The error information
display on the processor of multi-block data transfer.

Any advices are welcome!


2. Kernel configure:
CONFIG_MMC = y
CONFIG_MMC_DEBUG = y
CONFIG_MMC_BLOCK = y
CONFIG_MMC_SDHCI = y
CONFIG_MMC_SDHCI_PCI = y

3. Debug information:
