This causes my DMA memory to always be above 4GB no matter how much I delay the 
setting of the 64bit DMA mask. I find that if I set the DMA mask as 32bit and 
not increase it to 64 bit at all then all my I/O to the DVD rom are fine.

I agree and I have tested that it is working.

>ata1.00: XXX DMA address 202275000 is above 32bit

Tejun-I find the allocation always above 32bit with the following tests
-

1) kernel-2.6.24-rc5 + the 32 bit limiting patch that you provided in a
previous posting.
2) vanilla-2.6.24-rc5.

But I don't find the DMA allocation above 32bit in the kernel logs when
I apply my patch on the vanilla-2.6.24-rc5 kernel.

RE: [PATCH] sata_nv: fix ADMA ATAPI issues with memory over 4GB (v3)

2007-12-18 Thread Shyam_Iyer

ata1.00: XXX DMA address 202275000 is above 32bit

Tejun-I find the allocation always above 32bit with the following tests
-

1) kernel-2.6.24-rc5 + the 32 bit limiting patch that you provided in a
previous posting.
2) vanilla-2.6.24-rc5.

But I don't find the DMA allocation above 32bit in the kernel logs when
I apply my patch on the vanilla-2.6.24-rc5 kernel.

Re: Re: [PATCH] sata_nv: fix ADMA ATAPI issues with memory over 4GB (v3)

2007-12-17 Thread shyam_iyer

I found that the patch Robert has provided hasn't gone into 2.6.24-rc5 so maybe 
it is not working.

At the same time I did apply a small patch to 2.6.24-rc5 that seems to fix the 
issue.

I feel this could just be added to 2.6.24-rc5 without Robert's patch because of 
Jeff Garzik's" sata_nv: don't use legacy DMA in ADMA mode (v3)" patch.

It doesn't work without this patch because there is an allocation of memory 
from  hpriv before the mask can be set.

Please review.

Re: [PATCH] sata_nv: fix ADMA ATAPI issues with memory over 4GB (v3)

2007-12-17 Thread shyam_iyer

Hello,

I am seeing that this doesn't fix a Dell PowerEdge T105 which has the CK804 
chipset.

This system has a "HL-DT-ST" DVD-ROM (See dmesg with this posting) attached to 
the sata ports and has 8Gb physical memory.

The SATA DVD rom gets detected but any I/O like dd or mount is not successful.

If I reduce the memory with mem=<4Gb or disable the adma mode by passing 
adma=0, I am able to mount the media or do I/O.

Re: [PATCH] sata_nv: fix ADMA ATAPI issues with memory over 4GB (v3)

2007-12-17 Thread shyam_iyer

Hello,

I am seeing that this doesn't fix a Dell PowerEdge T105 which has the CK804 
chipset.

This system has a "HL-DT-ST" DVD-ROM (See dmesg with this posting) attached to 
the sata ports and has 8Gb physical memory.

The SATA DVD rom gets detected but any I/O like dd or mount is not successful.

If I reduce the memory with mem=<4Gb or disable the adma mode by passing 
adma=0, I am able to mount the media or do I/O.

Dmesg output -

Re: Re: [PATCH] sata_nv: fix ADMA ATAPI issues with memory over 4GB (v3)

2007-12-17 Thread shyam_iyer

I found that the patch Robert has provided hasn't gone into 2.6.24-rc5 so maybe 
it is not working.

At the same time I did apply a small patch to 2.6.24-rc5 that seems to fix the 
issue.

I feel this could just be added to 2.6.24-rc5 without Robert's patch because of 
Jeff Garzik's sata_nv: don't use legacy DMA in ADMA mode (v3) patch.

It doesn't work without this patch because there is an allocation of memory 
from  hpriv before the mask can be set.

Please review.
