2009-06-25 02:07:30 IDE to SATA requirement

billy zhou (UNITED STATES)

Message: 76292

I need the SATA support for BF531 uclinux

for example add an ide-to-sata bridge chip, now I use spif232A.

for my test, now it can detect the sata-hdd, but lost irq...

So I need your help, thanks a lot!

At first, you need config interrupt right in arch/blackfin/mach-xxx/boards/xxx.c:

#define PATA_INT IRQ_PF5 /* replace IRQ_PF5 by your irq */

static struct pata_platform_info bfin_pata_platform_data = {

.ioport_shift = 1,

.irq_flags = IRQF_TRIGGER_HIGH | IRQF_DISABLED,

};

static struct resource bfin_pata_resources[] = {

...

{

.start = PATA_INT,

.end = PATA_INT,

.flags = IORESOURCE_IRQ,

};

You should config kernel like:

x lqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqk x

x x --- Serial ATA (prod) and Parallel ATA (experimental) drivers x x

x x [*] SATA Port Multiplier support x x

x x [*] ATA SFF support x x

x x < > Marvell SATA support (HIGHLY EXPERIMENTAL) x x

x x <*> Generic platform device PATA support x x

To solve the "irq xx: nobody cared (try booting with the "irqpoll" option)" issue, in my test board, I made the following change to make SATA work normally:

I don't know whether this change can help you since I don't know your release version. Can you tell me the source codes version you are using, and can you post your log too? Thanks!

Yes, the version is much different. But the fault is same:

I knew the reason causing the problem.

Let me get your version to make SATA work.

I guess there are some connection problems or address setting issues.

You can use 2009R1 release to verify your hardware connection and start/end address set.

Remember to define PATA_INT as 0 in stamp.c. That will let ATA driver uses polling way to access disks. Drivers in 2008 release don't support the polling. As I know, it's sure that the polling way can work normally if the setting of HW and SW is right.

For interrupt way, you need to use my patch.

Thanks Barry.

I will try the 2009R1 release..

one question:

where I can download the 2009R1 release? svn uClinux-dist? trunk or 2009 branch?

Message: 76487

my download seems a little different,

I can't find this line in uclinux-dist-trunk-svn-8367/linux-2.6.x/arch/blackfin/mach-bf533/boards/stamp.c

#define PATA_INT IRQ_...

so I can't change it to #define PATA_INT 0//...

is this a promblem?

Billy,

you need increase platform device according to your board in stamp.c if it doesn't exist in common codes like

#if defined(CONFIG_PATA_PLATFORM) || defined(CONFIG_PATA_PLATFORM_MODULE)

#define PATA_INT 0

static struct pata_platform_info bfin_pata_platform_data = {

.ioport_shift = 1,

.irq_flags = IRQF_TRIGGER_HIGH | IRQF_DISABLED,

};

static struct resource bfin_pata_resources[] = {

{

.start = 0x...,

.end = 0x...,

.flags = IORESOURCE_MEM,

{

.start = 0x...,

.end = 0x...,

.flags = IORESOURCE_MEM,

{

.start = PATA_INT,

.end = PATA_INT,

.flags = IORESOURCE_IRQ,

};

static struct platform_device bfin_pata_device = {

.name = "pata_platform",

.id = -1,

.num_resources = ARRAY_SIZE(bfin_pata_resources),

.resource = bfin_pata_resources,

.dev = {

.platform_data = &bfin_pata_platform_data,

}

};

#endif

static struct platform_device *stamp_devices[] __initdata = {

...

#if defined(CONFIG_PATA_PLATFORM) || defined(CONFIG_PATA_PLATFORM_MODULE)

&bfin_pata_device,

#endif

...

}

Otherwise, there will be no any detection operation at all.

After you make sure the polling is ok, you can change PATA_INT to real IRQ number. Codes in 2009r1 and trunk head of svn are all ok in interrupt mode now.
