known working sata_sil24.c setup on powerpc platforms?

known working sata_sil24.c setup on powerpc platforms?

[Leon Woestenberg]

Hello,

after investigating problems with sata_sil24.c on a freescale p2020
soc, I wonder if this driver works on powerpc at all?

Does anyone know of a working setup of sata_sil24 on a big endian
powerpc system?

Regards,

Our P2020 boards work fine with legacy PCI interrupts (I think it's a sil3124 over PCI-E); the only deficiency is that MSI does not seem to work.

I know our MSI *does* work in general because we have an Intel 82571EB chipset also attached via PCI-E with working MSI.

Our P2020 boards work fine with legacy PCI interrupts (I think it's a sil31=
24 over PCI-E); the only deficiency is that MSI does not seem to work.

I know our MSI *does* work in general because we have an Intel 82571EB chip=
set also attached via PCI-E with working MSI.

We've definitely had issues with sata_sil24 + MSI, also...

sata_sil24 does work on big endian in general.

Re: known working sata_sil24.c setup on powerpc platforms?

[Felix Radensky]

Hi Leon,

I think there's a hardware problem with mini PCI-E slot
on P2020RDB related to legacy IRQ routing. See this
thread for details
http://www.mail-archive.com/linuxppc-dev@lists.ozlabs.org/msg40037.html

You may have better luck with PCI-E slot and mini PCI-E to
PCI-E adapter.

Felix.

Thanks for the heads-up.

Unfortunately the PCIe is slot already occupied, so that's why I
searched for and found the Mini PCIe Sil3132 card.

Legacy IRQ routing on PCIe is broken in what sense? Software (device
tree, kernel) or silicon (p2020) ?

On the MSI side, I'm getting quite far on transfers, but at one point
the device stalls. Maybe a race condition in interrupt handling in
sata_sil24.c?

It's a board design problem specific to P2020RDB. Maybe it's
fixed in latest board revisions. I have P2020RDB rev C and the
problem is still there. Freescale people on the list should know
better.

Sorry, cannot help you with that. I have no experience with
sata_sil24.

Re: known working sata_sil24.c setup on powerpc platforms?

[Leon Woestenberg]

Hello Prabhakar,

thanks for your response. My answer below:

No, the p1020rdb and p2020rdb do not have the IDSEL entries:

http://lxr.linux.no/#linux+v2.6.38/arch/powerpc/boot/dts/p2020rdb.dts

whereas the p2020ds has:

http://lxr.linux.no/#linux+v2.6.38/arch/powerpc/boot/dts/p2020ds.dts


What would the correct IDSEL entries be?

Also, did you see the reference to Felix' thread?
"Problem with mini-PCI-E slot on P2020RDB"

Best regards,

Leon.

Re: known working sata_sil24.c setup on powerpc platforms?

[Leon Woestenberg]

Hello Prabhakar,

thanks for your response. My answer below:

No, the p1020rdb and p2020rdb do not have the IDSEL entries:

http://lxr.linux.no/#linux+v2.6.38/arch/powerpc/boot/dts/p2020rdb.dts

whereas the p2020ds has:

http://lxr.linux.no/#linux+v2.6.38/arch/powerpc/boot/dts/p2020ds.dts


What would the correct IDSEL entries be?

Also, did you see the reference to Felix' thread?
"Problem with mini-PCI-E slot on P2020RDB"

Best regards,

Leon.

For legacy interrupt to work IDSEL values are required.. please find the correct IDSEL values for pci0/1.

	pci0: pcie@ffe09000 {
		 ---
		 ---
		interrupt-map-mask = <0xf800 0x0 0x0 0x7>;
		interrupt-map = <
			/* IDSEL 0x0 */
			0000 0x0 0x0 0x1 &mpic 0x4 0x1

	};

	pci1: pcie@ffe0a000 {

		interrupt-map-mask = <0xf800 0x0 0x0 0x7>;
		interrupt-map = <
			/* IDSEL 0x0 */

	};
};

Please try with this.. I am in process of pushing these IDSEL values to upstream.

I will look into it..

For legacy interrupt to work IDSEL values are required.. please find the co=
rrect IDSEL values for pci0/1.

	pci0: pcie@ffe09000 {
		 ---
		 ---
		interrupt-map-mask =3D <0xf800 0x0 0x0 0x7>;
		interrupt-map =3D <
			/* IDSEL 0x0 */
			0000 0x0 0x0 0x1 &mpic 0x4 0x1
			0000 0x0 0x0 0x2 &mpic 0x5 0x1
			0000 0x0 0x0 0x3 &mpic 0x6 0x1
			0000 0x0 0x0 0x4 &mpic 0x7 0x1
			>;
	      ---

	};

	pci1: pcie@ffe0a000 {
		 ---
		 ---
		interrupt-map-mask =3D <0xf800 0x0 0x0 0x7>;
		interrupt-map =3D <
			/* IDSEL 0x0 */
			0000 0x0 0x0 0x1 &mpic 0x0 0x1
			0000 0x0 0x0 0x2 &mpic 0x1 0x1

	};
};

Please try with this.. I am in process of pushing these IDSEL values to ups=
tream.=20

I will look into it..=20

Do you have these for P1020RDB  as well? I found a P1020RDB board that
has the CE10 errata fixed, so IRQ0 is properly pulled up.

  Same IDSEL values are valid for P1020RDB also.

I compiled the new device tree binary, the dump is below(*) and booted
the P1020RDB from that.

I verified using an oscilloscope that IRQ0 indeed remains high.

However, no interrupt seems to come in from the sata_sil24 driver, see
boot log (**).

I compiled the new device tree binary, the dump is below(*) and booted
the P1020RDB from that.

I verified using an oscilloscope that IRQ0 indeed remains high.

However, no interrupt seems to come in from the sata_sil24 driver, see
boot log (**).

RE: known working sata_sil24.c setup on powerpc platforms?

[Kushwaha Prabhakar-B32579]

Hi Leon, 
 
 interrupt-map-mask is missing for pcie@ffe0a000 node. Please see my comment there... 
pcie@ffe0a000 node deals with mini-PCIe. 

one more thing, can you please tell P1020Si version. It will be there on u-boot log.

RE: known working sata_sil24.c setup on powerpc platforms?

[Kushwaha Prabhakar-B32579]

Hi Leon,=20
=20
 interrupt-map-mask is missing for pcie@ffe0a000 node. Please see my commen=
t there...=20
pcie@ffe0a000 node deals with mini-PCIe.=20

one more thing, can you please tell P1020Si version. It will be there on u-=
boot log.

Re: known working sata_sil24.c setup on powerpc platforms?

[Leon Woestenberg]

Hello Prabhakar,

I have P1020E 1.0 silicon (0x80ec0010) on my P1020RDB.

With the addition of the interrupt-map-mask (thanks, miscopied that) I
get interrupt #16.

However, it keeps continously firing (*). I have verified that the
Sil3132 device itself has no interrupt pending (the interrupt status
register reads zero).

printing the Sil3132 interrupt status register, which reads 0, no

This means level sensitive, active low.


The external IRQ0 is pulled high, verified by scope.

Re: known working sata_sil24.c setup on powerpc platforms?

[Leon Woestenberg]

Hello Prabhakar,

I have P1020E 1.0 silicon (0x80ec0010) on my P1020RDB.

With the addition of the interrupt-map-mask (thanks, miscopied that) I
get interrupt #16.

However, it keeps continously firing (*). I have verified that the
Sil3132 device itself has no interrupt pending (the interrupt status
register reads zero).

printing the Sil3132 interrupt status register, which reads 0, no
interrupts pending).

RE: known working sata_sil24.c setup on powerpc platforms?

Hi Leon,

Finally interrupt came :)

For this continuously firing of interrupt. Can you please check the u-boot code for following patch..
	" p1_p2_rdb: to set SQW/INT pin of RTC as INT line
	 Commit id: 39c2a6eb75fabd9745c5762c8dec9d1a85dabf00 "

This patch is already present at  u-boot@lists.denx.de.  Or you can apply it on u-boot. 

Regards,
Prabhakar

Subject: [PATCH] p1_p2_rdb: to set SQW/INT pin of RTC as INT line

SQW/INT pin in RTC can be used for generating square wave(by default) or
as interrupt line.  U-boot is registering this pin for interrupts.
Configuring SQW/INT bit as interrupt line during board initialization
to avoid spurious interrupts generated by square wave.

Hi Leon,

Finally interrupt came :)

For this continuously firing of interrupt. Can you please check the u-boot code for following patch..
	" p1_p2_rdb: to set SQW/INT pin of RTC as INT line
	 Commit id: 39c2a6eb75fabd9745c5762c8dec9d1a85dabf00 "

This patch is already present at  u-boot@lists.denx.de.  Or you can apply it on u-boot. 

Regards,
Prabhakar

[-- Type: application/octet-stream, Size: 2015 bytes --]

From 39c2a6eb75fabd9745c5762c8dec9d1a85dabf00 Mon Sep 17 00:00:00 2001

Subject: [PATCH] p1_p2_rdb: to set SQW/INT pin of RTC as INT line

SQW/INT pin in RTC can be used for generating square wave(by default) or
as interrupt line.  U-boot is registering this pin for interrupts.
Configuring SQW/INT bit as interrupt line during board initialization
to avoid spurious interrupts generated by square wave.

Indeed, I confirm a 32.68 Hz square wave entering the interrupt pin,
now that will keep the system busy :-)

Will perform that u-boot fix on my P2020RDB later.

I'll report back whether this solves the setup problems, your IDSEL
patch seems to work.

Thanks for wading through the issues one by one!

Best regards,

Leon.

Indeed, I confirm a 32.68 Hz square wave entering the interrupt pin,
now that will keep the system busy :-)

Will perform that u-boot fix on my P2020RDB later.

I'll report back whether this solves the setup problems, your IDSEL
patch seems to work.

Thanks for wading through the issues one by one!

Best regards,

Leon.
