Yosemite/440EP why are readl()/ioread32() setup to read little-endian?

[David Hawkins]

Hi all,

I was writing a simple driver to test IRQ handling on the
AMCC Yosemite board. The board has an 8x2 header with several
GPIO pins, a number of which can be configured as IRQ inputs.

I plan to setup GPIO46 as output, and GPIO47 as input, and
select IRQ8 on that pin.

The GPIO46 and GPIO47 are configured via the GPIO1 registers
at 0xEF600C00. U-Boot can be used to read the register values:

=> md ef600c00 b
ef600c00: 00000000 c2000000 50080000 00000000    ........P.......
ef600c10: 00000000 00000000 00000000 3ffcfffd    ............?...
ef600c20: 00000000 00000000 00000000    ............

=> md ef600c30 6
ef600c30: 00000400 00000000 00010000 00000000    ................
ef600c40: 00000000 00000000    ........
=>

So

ef600c00  GPIO1_OR    = 00000000
ef600c04  GPIO1_TCR   = c2000000
ef600c30  GPIO1_ISR1L = 00000400

However, if I read those same registers back under Linux,
using the driver code pasted at the end of this message
I get:

# insmod yosemite_gpio.ko
- remap the GPIO registers
- remapped to address 0xD1008C00

- Read some GPIO1 registers using readl()
- GPIO1_OR    = 0x00000000
- GPIO1_TCR   = 0x000000C2
- GPIO1_ISR1L = 0x00040000

- Read some GPIO1 registers using ioread32()
- GPIO1_OR    = 0x00000000
- GPIO1_TCR   = 0x000000C2
- GPIO1_ISR1L = 0x00040000

- Read some GPIO1 registers using an integer pointer
- GPIO1_OR    = 0x00000000
- GPIO1_TCR   = 0xC2000000
- GPIO1_ISR1L = 0x00000400

readl() and ioread32() read the registers in little-endian format!

Looking at asm-ppc/io.h

  - ioread32() is just a readl()
  - line 180 (2.6.13) has readl() as in_le32()
    (the code is the same in the 2.6.15-denx kernel too)

So, this explains why the data is read in little-endian format,
but not why this was done.

If the processor was reading from the PCI bus, then sure, I
could understand why this might be used, but even then, that
should be up to the user, eg. by using cpu_to_le32 etc.

Should I just be using pointers for remapped processor
registers, and only use readl(), ioread32(), etc, on external
memory?

I know this is just a big-endian/little-endian issue, I'm
really just asking for the driver writing 'best practices'
in this regard.

Looking forward to enlightenment :)

Cheers
Dave

Yosemite/440EP is there a global interrupt enable mask?

[David Hawkins]

Hi all,

I'm writing a simple driver to test IRQ handling on the
AMCC Yosemite board. The board has an 8x2 header with several
GPIO pins, a number of which can be configured as IRQ inputs.

I have setup GPIO46 as output, and GPIO47 as input, and
selected IRQ8 on that pin.

The simple driver sets up the IRQ handler, and then drops
into a loop where it pulses the GPIO47 output. The relevent
messages from this loop are:

  - Read some GPIO1 registers
  - GPIO1_OR    = 0x00020000
  - GPIO1_TCR   = 0xC2020000
  - GPIO1_ISR1L = 0x00000401
  - enable IRQ8
  - UIC1_SR = 0x00002800
  - UIC1_ER = 0xE0801008

IRQ8 is bit 19 in the enable register, i.e., 1 << (31-19) = 1000h
So, clearly its enabled here.

  - sleep for 1s
  - UIC1_SR = 0x00002800
  - UIC1_ER = 0xE0801008

And after a sleep for 1s its still enabled.

  ----- loop test -----
  - generate low on GPIO46
  - sleep for 10 ticks
  - generate high on GPIO46
  - UIC1_SR = 0x00003800
  - UIC1_ER = 0xE0800008
  - IRQ8 status is set, clearing it
  - UIC1_SR = 0x00002800
  - UIC1_ER = 0xE0800008
  - sleep for 10 ticks
  ... repeats ...

The low pulse on the GPIO46 pin definitely set the IRQ8 status
bit, but why on earth is the enable bit cleared!

(I added the check for the status bit being set, since my
IRQ handler was not getting called)

To enable the IRQ8 line, I simply accessed the UIC1_ER register
directly via

   reg = mfdcr(DCRN_UIC_ER(UIC1));
   reg |= 1 << (31-19);
   mtdcr(DCRN_UIC_ER(UIC1), reg);

So, is there a kernel wide interrupt enable mask that I really
should be using? Or, an interrupt enable API? I initially
thought that when I registered an interrupt using
request_irq() that the kernel would go off an enable the
requested IRQ, but this test shows that it did not.

Any ideas?

Cheers
Dave

Correct. That's how it is implemented on all platforms. Think for example of 
an pci device driver. Using these IO functions, the driver will become 
platform independent, running without modifications on little- and big-endian 
machines.

No. Please see above.

That's how I do it. Only use readl() and friends for pci spaces (or other 
little endian memory mapped areas).

Stefan

Yes, the request_irq() should enable the requested IRQ. You seem to have used 
the wrong IRQ number though. Please see below.

You are using the "External IRQ 8". This results in IRQ number 19 of the 2nd 
interrupt controller of the 440ep. So please try (19+32) as the IRQ number 
upon requesting the interrupt.

Best regards,

Ok, I figured that was probably the case. Thanks for the confirmation.

I took a look at the Yosemite network and USB drivers, it looks like
the authors of those drivers chose to use in_be32() and out_be32().

Personally I like the concept of using pointers, or more usefully
pointers to structure overlays for device control. However, the
impression I have is that this is inherently more non-portable
than using the readl()/writel(), ioread32()/iowrite32(), and
now I guess I can add in_be32()/out_be32() to that list.

But if you use pointers, thats good enough for me!

Dave

Yep, that was it!

Now while looking at some of the other drivers, I noticed the use
of the following syntax:

   unsigned long flags;
   local_irq_save(flags);

   ... mfdcr, mtdcr, etc operations ...

   local_irq_restore(flags);

which is treating the operations on the DCRs as a critical section.

I should probably be doing the same when I enable the external IRQs
and modify the GPIO registers.

Any comments on that?

use in_/out_ accessors, not pointers. Look at other 4xx drivers (i2c, 
emac)

Also, you don't have worry about this code being non-portable, because 
every chip has it's own GPIO impl anyway.

You have to use locks if you access GPIO registers, because other bits 
can be used by other device drivers, although there is no drivers in 
the official tree which use GPIO (I have tons of them in my private 
tree and I added global "gpio_lock" to serialize GPIO access).

DCRs are a little different, there are separate DCR for different 
peripherals, so generally, you don't have to use locks, because those 
DCR accesses are implicitly bound to particular device anyway and 
device "owns" them.

Thanks for the feedback.

I haven't looked for it yet, but do you know if there is a driver
for the Yosemite board I2C temperature sensor already written?

If its not, that might be a nice little exercise for me.

What kind of global lock; a spinlock?

What is the advantage of say using the gpio_lock, rather than
the irq_save/restore sequence above - which is what is used in
the emac and usb code?

Right, but I was accessing the DCR for the UIC status register,
which, I assume, is also used by the Linux IRQ handling subsystem.

Well, ok perhaps that is not a good example, I have not tested
whether the IRQ handler in the example code I posted needs to
clear the UIC1_SR bit, or whether the Linux IRQ handling code
already takes care of it. I suspect the latter, since the IRQ
could be shared, and Linux needs to go through and call all
handlers on that IRQ line.

But in a debug context of reading those registers, I would
expect some form of lock holding would be recommended.
Do you happen to know if the Linux IRQ handling code uses a
lock?

I'm just learning, so feel free to enlighten me.

What drivers do you have in your 'private' tree that you might
be willing to share?

I'm planning on putting the 440EP on custom boards with a
number of Altera FPGAs located in the peripheral bus. I'll
post results and code as I go. Ulimately I'll open-source
the lot (hardware and all).

Here's the existing hardware I'm revising:

I have no idea what temp sensor is used in this board, but it's very 
likely that lm-sensors project already has a driver for it (look 
under Drivers/Hardware Monitoring support).

yes, spinlock.

emac doesn't use GPIO registers :). Also, if there is no IRQ code 
accesses GPIO registers, you don't need IRQ disabling lock, and 
spin_lock effectively becomes just a preemption lock. Personally, I use 
spinlocks just out of habit, I think it's a good style, even if you 
know your chip doesn't support SMP (but some day might :).

DO NOT access UIC registers directly. DO NOT.

4xx IRQ code takes care of all this. You don't need to mess with UIC 
registers. 4xx PIC code doesn't use locks because it's being called 
from special context (IRQs disabled), 4xx doesn't support SMP and PIC 
code "owns" those DCRs.

Nothing that can be of interest for a general public. They are 
board-specific (lots of bit-banging SPI stuff). All other drivers I 
wrote are already in public tree.

Okay :)

With regard to SPI drivers. Has the 2.6 kernel implemented
an SPI 'bus' interface (like PCI, OCP, etc). The 440EP also
has an SPI interface that I plan to look at.

The custom boards will need temperature sensing and other
monitoring jobs. I want to see what kind of overhead both
the I2C and SPI bus require. If its too much, then I'll
move those tasks out into an FPGA FSM.

The PowerPC's main job will be reading FPGA data every 1ms,
int-to-float conversions, FFT, and accumulation.

The Analog Devices AD7414 is used on Yosemite/Yellowstone and it doesn't seem 
to be supported from the lm-sensors project right now. Shouldn't be that 
difficult to write a driver for it though.

Thanks Stefan, I'll take a shot at it then.

Hey Stefan,

I just stumbled across the section in Rubini 3rd Ed that mislead
me into believing that the readl()/writel() were machine endianness
dependent, i.e., LE on x86, BE on PPC.

p453 of his book has a PCI DMA example, where he uses the
cpu_to_le32() macros inside calls writel().

However, since these functions are internally implemented to
perform LE operations, this example appears to be incorrect.

Would you agree?

I just checked the Oreilly web site for errata's and this is not
listed. If you agree that the example is incorrect, then I'll
submit an errata.
