[openib-general] mstflint error on ppc64 bug fix

Sun Nov 19 07:53:33 PST 2006

Thanks.
The right thing is no to swap PSID regardless of endian-ness though.
I'll give it a look.

Michael,

Looking at the attached error file will show a big endian data displayed in wrong little endian order.

The attached file mstflint2.patch fix this problem.

The  mstflint2.patch  has to be used after mstflint.patch packed in the OFED-1.1 openib.tgz.(user_patches...)

The patch change only the displayed data and not the program's used internal structures , as I found that data write is performed o.k.
 and I did not want to cause errors in the writing process .

	Hi Michael,

	The output of mstflint is changed on ppc64 as result of byte ordering issues.

	If you take a HCA that was burned using x86_64 or Mellanox manufacturing  and perform mstflint -d ... q  on ppc64
	you'll find that the value of PSID VSD and Board Id was changed.

	I tried to look at the code to find the error,

	but then I saw that vsd is defined twice in the code according to it's usage (char[205], or unsigned int[52] )

	Can you please look and help ?

	Best regards,

	Moshe

Burn process will not be failsafe. No checks are performed.
ALL flash, including Invariant Sector will be overwritten.
If this process fails computer may remain in inoperable state.
