No longer terribly relevant these days but still broken and just an eyesore
mess of neglience just as I've already raised it a few days ago.  Time to
sort this.

drivers/input/misc/pcspkr.c:

#if defined(CONFIG_MIPS) || defined(CONFIG_X86)
/* Use the global PIT lock ! */
#include <asm/i8253.h>
#else
#include <asm/8253pit.h>
static DEFINE_RAW_SPINLOCK(i8253_lock);
#endif

sound/drivers/pcsp/pcsp.h:

#if defined(CONFIG_MIPS) || defined(CONFIG_X86)
/* Use the global PIT lock ! */
#include <asm/i8253.h>
#else
#include <asm/8253pit.h>
static DEFINE_RAW_SPINLOCK(i8253_lock);

$ git grep -F pcsp.h sound/drivers/pcsp
sound/drivers/pcsp/pcsp.c:#include "pcsp.h"
sound/drivers/pcsp/pcsp_input.c:#include "pcsp.h"
sound/drivers/pcsp/pcsp_lib.c:#include "pcsp.h"
sound/drivers/pcsp/pcsp_mixer.c:#include "pcsp.h"
$ git grep -w i8253_lock sound/drivers/pcsp/
sound/drivers/pcsp/pcsp.h:static DEFINE_RAW_SPINLOCK(i8253_lock);
sound/drivers/pcsp/pcsp_input.c:        raw_spin_lock_irqsave(&i8253_lock, flags
sound/drivers/pcsp/pcsp_input.c:        raw_spin_unlock_irqrestore(&i8253_lock, 
sound/drivers/pcsp/pcsp_lib.c:          raw_spin_lock_irqsave(&i8253_lock, flags
sound/drivers/pcsp/pcsp_lib.c:          raw_spin_unlock_irqrestore(&i8253_lock, 
sound/drivers/pcsp/pcsp_lib.c:  raw_spin_lock(&i8253_lock);
sound/drivers/pcsp/pcsp_lib.c:  raw_spin_unlock(&i8253_lock);
sound/drivers/pcsp/pcsp_lib.c:  raw_spin_lock(&i8253_lock);
sound/drivers/pcsp/pcsp_lib.c:  raw_spin_unlock(&i8253_lock);

Locks are great, everybody should have their own lock!

$ find . -name 8253pit.h
./arch/powerpc/include/asm/8253pit.h
./arch/alpha/include/asm/8253pit.h
$ cat arch/*/include/asm/8253pit.h
/*
 * 8253/8254 Programmable Interval Timer
 */
/*
 * 8253/8254 Programmable Interval Timer
 */
$

Eh...

$ git grep -w PCSPKR_PLATFORM 
arch/mips/Kconfig:      select PCSPKR_PLATFORM
arch/mips/Kconfig:      select PCSPKR_PLATFORM
arch/mips/Kconfig:      select PCSPKR_PLATFORM
arch/powerpc/platforms/amigaone/Kconfig:        select PCSPKR_PLATFORM
drivers/input/misc/Kconfig:     depends on PCSPKR_PLATFORM
init/Kconfig:config PCSPKR_PLATFORM
sound/drivers/Kconfig:  depends on PCSPKR_PLATFORM && X86 && HIGH_RES_TIMERS

So the status is:

 Alpha:		There is no PCSPKR_PLATFORM so while a platform device is
		being installed no drivers will be built.  I don't know
		which Alpha platforms or even if all of Alpha should be
		doing a PCSPKR_PLATFORM so I haven't even tried to sort
		this.
 ARM:		No PC speaker supported, yeah :)
 PowerPC:	Should compile but the locking is wrong but only the AmigaOne
   		platforms should be affected.
 MIPS:		Ok.
 x86:		Ok.
 All others:	No PC speaker supported

Also only the plain old IBM PC XT was using a i8253; every later system
had i8254.  So maybe this is the time for renaming the support code?

[-- Attachment #1: i8253-cleanup-x86-global_clock_event.patch --]
[-- Type: text/plain, Size: 3677 bytes --]

There are multiple declarations of global_clock_event in header files
specific to particular clock event implementatiosn.  Consolidate them
in <asm/time.h> and make sure all users include that header.

[-- Attachment #1: i8253-sort-out-pit_latch-definitions.patch --]
[-- Type: text/plain, Size: 2715 bytes --]

x86 defines PIT_LATCH as LATCH which in <linux/timex.h> is defined as
((CLOCK_TICK_RATE + HZ/2) / HZ) and <asm/timex.h> again defines
CLOCK_TICK_RATE as PIT_TICK_RATE.

MIPS defines PIT_LATCH as LATCH which in <linux/timex.h> is defined as
((CLOCK_TICK_RATE + HZ/2) / HZ) and <asm/timex.h> again defines
CLOCK_TICK_RATE as 1193182.

ARM defines PITCH_LATCH as ((PIT_TICK_RATE + HZ / 2) / HZ) - and that's
the sanest thing and equivalent to above definitions so use that as the
new definition in <linux/i8253.h>.

Lenghty lists of the kind "depends on ARCH1 || ARCH2 ... || ARCH123" are

[-- Type: text/plain, Size: 1464 bytes --]

Only the Siemens-Nixdorf RM series workstations and the Jazz family
workstations have PC speakers built in; Malta can connect one via the
infamous AMR connector with an AMR sound card or a little creativity.
So we don't want to offer the PC speaker driver on all MIPS systems.

The Kconfig dependencies cleanup patch for CHRP, PSERIES, etc. should
also apply to the AmigaOne. Can you resend it with a fix for the
AmigaOne, or should I send a patch?
I'll check next week, if the PC speaker is still working on my AmigaOne.

Thanks,
Gerhard

I can sort that; it's easy enough.

I can't imagine that it's going to break - the code is sorta simple ;-)

One obscurity I noticed is this bit in the amigaone.dts:

        timer@40 {
                // Also adds pcspkr to platform devices.
                compatible = "pnpPNP,100";
                reg = <1 0x00000040 0x00000020>;
        };

Shouldn't that rather be something like the following?

        pcspeaker@61 {
                device_type = "sound";
                compatible = "pnpPNP,800";
                reg = <1 0x61 1>;
        };

pnpPNP,100 is the i8253 timer as I understand and pnpPNP,800 the PC speaker.
If you interpret pnpPNP,100 to imply the presence of a PC speaker you can't
express a system that has a i8253 but no PCspeaker in a DT so maybe
amigaone.dts and arch/powerpc/kernel/setup-common.c should be changed to
use pnpPNP,800 instead?

That's true, but testing the most recent Linux kernel on the AmigaOne is
never wrong. :-)

That would be cleaner, but I guess it would break CHRP and PSERIES.
These platforms probably only provide a pnpPNP,100 entry in the device
tree (at least that's the case on the Pegasos2 CHRP machine AFAICT).

That's true, but testing the most recent Linux kernel on the AmigaOne is
never wrong. :-)

That would be cleaner, but I guess it would break CHRP and PSERIES.
These platforms probably only provide a pnpPNP,100 entry in the device
tree (at least that's the case on the Pegasos2 CHRP machine AFAICT).

i8253: Consolidate all kernel definitions of i8253_lock

Move them to drivers/clocksource/i8253.c and remove the
implementations in arch/

[ tglx: Avoid the extra file in lib - folded arch patches in. The
  export will become conditional in a later step ]

alpha: i8253: Cleanup remaining users of i8253pit.h

The Alpha <asm/i8253pit.h> header is empty so this inclusion can just be
removed.

x86: i8253: Consolidate definitions of global_clock_event

There are multiple declarations of global_clock_event in header files
specific to particular clock event implementations.  Consolidate them
in <asm/time.h> and make sure all users include that header.

i8253: Consolidate definitions of PIT_LATCH

x86 defines PIT_LATCH as LATCH which in <linux/timex.h> is defined as
((CLOCK_TICK_RATE + HZ/2) / HZ) and <asm/timex.h> again defines
CLOCK_TICK_RATE as PIT_TICK_RATE.

MIPS defines PIT_LATCH as LATCH which in <linux/timex.h> is defined as
((CLOCK_TICK_RATE + HZ/2) / HZ) and <asm/timex.h> again defines
CLOCK_TICK_RATE as 1193182.

ARM defines PITCH_LATCH as ((PIT_TICK_RATE + HZ / 2) / HZ) - and that's
the sanest thing and equivalent to above definitions so use that as the
new definition in <linux/i8253.h>.

i8253: Move remaining content and delete asm/i8253.h

Move setup_pit_timer() declaration to the common header file and
remove the arch specific ones.

[ tglx: Move it to linux/i8253.h instead of asm/mips and asm/x86 ]

pcspkr: Cleanup Kconfig dependencies

Lenghty lists of the kind "depends on ARCH1 || ARCH2 ... || ARCH123" are
usually either wrong or too coarse grained.  Or plain an ugly sin.

pcpskr: MIPS: Make config dependencies finer grained

Only the Siemens-Nixdorf RM series workstations and the Jazz family
workstations have PC speakers built in; Malta can connect one via the
infamous AMR connector with an AMR sound card or a little creativity.
So we don't want to offer the PC speaker driver on all MIPS systems.

i8253: Consolidate all kernel definitions of i8253_lock

Move them to drivers/clocksource/i8253.c and remove the
implementations in arch/

[ tglx: Avoid the extra file in lib - folded arch patches in. The
  export will become conditional in a later step ]

x86: i8253: Consolidate definitions of global_clock_event

There are multiple declarations of global_clock_event in header files
specific to particular clock event implementations.  Consolidate them
in <asm/time.h> and make sure all users include that header.

i8253: Consolidate definitions of PIT_LATCH

x86 defines PIT_LATCH as LATCH which in <linux/timex.h> is defined as
((CLOCK_TICK_RATE + HZ/2) / HZ) and <asm/timex.h> again defines
CLOCK_TICK_RATE as PIT_TICK_RATE.

MIPS defines PIT_LATCH as LATCH which in <linux/timex.h> is defined as
((CLOCK_TICK_RATE + HZ/2) / HZ) and <asm/timex.h> again defines
CLOCK_TICK_RATE as 1193182.

ARM defines PITCH_LATCH as ((PIT_TICK_RATE + HZ / 2) / HZ) - and that's
the sanest thing and equivalent to above definitions so use that as the
new definition in <linux/i8253.h>.

i8253: Move remaining content and delete asm/i8253.h

Move setup_pit_timer() declaration to the common header file and
remove the arch specific ones.

[ tglx: Move it to linux/i8253.h instead of asm/mips and asm/x86 ]

pcspkr: Cleanup Kconfig dependencies

Lenghty lists of the kind "depends on ARCH1 || ARCH2 ... || ARCH123" are
usually either wrong or too coarse grained.  Or plain an ugly sin.

pcpskr: MIPS: Make config dependencies finer grained

Only the Siemens-Nixdorf RM series workstations and the Jazz family
workstations have PC speakers built in; Malta can connect one via the
infamous AMR connector with an AMR sound card or a little creativity.
So we don't want to offer the PC speaker driver on all MIPS systems.
