aty128fb: fix blanking

I have a problem with blanking. The soundcard uses speakers of the monitor.
Sound is muted when the screen blanks due to a bug in aty128fb.c.

Here is a fragment of linux/fb.h
/* VESA Blanking Levels */
#define VESA_NO_BLANKING        0
#define VESA_VSYNC_SUSPEND      1
#define VESA_HSYNC_SUSPEND      2
#define VESA_POWERDOWN          3

enum {
        /* screen: unblanked, hsync: on,  vsync: on */
        FB_BLANK_UNBLANK       = VESA_NO_BLANKING,

        /* screen: blanked,   hsync: on,  vsync: on */
        FB_BLANK_NORMAL        = VESA_NO_BLANKING + 1,

        /* screen: blanked,   hsync: on,  vsync: off */
        FB_BLANK_VSYNC_SUSPEND = VESA_VSYNC_SUSPEND + 1,

        /* screen: blanked,   hsync: off, vsync: on */
        FB_BLANK_HSYNC_SUSPEND = VESA_HSYNC_SUSPEND + 1,

        /* screen: blanked,   hsync: off, vsync: off */
        FB_BLANK_POWERDOWN     = VESA_POWERDOWN + 1
};

So FB_BLANK_NORMAL is 1, FB_BLANK_VSYNC_SUSPEND is 2,
FB_BLANK_HSYNC_SUSPEND is 3, FB_BLANK_POWERDOWN is 4.
And now:
blank = FB_BLANK_NORMAL (1)
blank & FB_BLANK_HSYNC_SUSPEND (1 & 3) is true,
so normal blank caused hsync suspend and sound is muted.

x86, serial: convert legacy COM ports to platform devices

Make x86 COM ports into platform devices and don't probe for them
if we have PNP.

This prevents double discovery, where a device was found both by
the legacy probe and by 8250_pnp, e.g.,

    serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
    00:02: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A

This also means IRDA devices without a UART PNP ID will no longer be
claimed by the serial driver, which might require changes in IRDA
drivers and administration.

In addition to this patch, you may need to configure a setserial init
script, e.g., /etc/init.d/setserial, so it doesn't poke legacy UART
stuff back in.  On Debian, "dpkg-reconfigure setserial" with the "kernel"
option does this.

To force the old legacy probe behavior even when we have PNPBIOS or
ACPI, load the new legacy_serial module (or build 8250 static) with
the "legacy_serial.force" option.

17 years agosmsc-ircc2: add PNP support
Bjorn Helgaas [Tue, 8 May 2007 07:36:05 +0000 (00:36 -0700)]
smsc-ircc2: add PNP support

Claim devices using PNP, unless the user explicitly specified device
addresses.  This can be disabled with the "smsc-ircc2.nopnp" option.

This removes the need for probing legacy addresses and helps untangle IR
devices from serial8250 devices.

Sometimes the SMC device is at a legacy COM port address but does not use the
legacy COM IRQ.  In this case, claiming the device using PNP rather than 8250
legacy probe means we can automatically use the correct IRQ rather than
forcing the user to use "setserial" to set the IRQ manually.

If the PNP claim doesn't work, make sure you don't have a setserial init
script, e.g., /etc/init.d/setserial, configured to poke in legacy COM port
resources for the IRDA device.  That causes the serial driver to claim
resources needed by this driver.

PNP: notice whether we have PNP devices (PNPBIOS or PNPACPI)

This series converts i386 and x86_64 legacy serial ports to be platform
devices and prevents probing for them if we have PNP.

This prevents double discovery, where a device was found both by the legacy
probe and by 8250_pnp.

This also prevents the serial driver from claiming IRDA devices (unless they
have a UART PNP ID).  The serial legacy probe sometimes assumed the wrong IRQ,
so the user had to use "setserial" to fix it.

Removing the need for setserial to make IRDA devices work seems good, but it
does break some things.  In particular, you may need to keep setserial from
poking legacy UART stuff back in by doing something like "dpkg-reconfigure
setserial" with the "kernel" option.  Otherwise, the setserial-discovered
"UART" will claim resources and prevent the IRDA driver from loading.

This patch:

If we can discover devices using PNP, we can skip some legacy probes.  This
flag ("pnp_platform_devices") indicates that PNPBIOS or PNPACPI is enabled and
should tell us about builtin devices.

17 years agoAdd IRQF_IRQPOLL flag (common code)
Bernhard Walle [Tue, 8 May 2007 07:35:24 +0000 (00:35 -0700)]
Add IRQF_IRQPOLL flag (common code)

irqpoll is broken on some architectures that don't use the IRQ 0 for the timer
interrupt like IA64.  This patch adds a IRQF_IRQPOLL flag.

Each architecture is handled in a separate pach.  As I left the irq == 0 as
condition, this should not break existing architectures that use timer_irq ==
0 and that I did't address with that patch (because I don't know).

This patch:

This patch adds a IRQF_IRQPOLL flag that the interrupt registration code could
use for the interrupt it wants to use for IRQ polling.

Because this must not be the timer interrupt, an additional flag was added
instead of re-using the IRQF_TIMER constant.  Until all architectures will
have an IRQF_IRQPOLL interrupt, irq == 0 will stay as alternative as it should
not break anything.

Also, note_interrupt() is called on CPU-specific interrupts to be used as
interrupt source for IRQ polling.

i386:

  implicit declarations of cmpxchg symbols.  The i386 build presumably isn't
  seeing this because a separate inclusion of system.h is covering it over.

  The cmpxchg stuff is moved to asm-i386/cmpxchg.h, with an include left in
  system.h for the benefit of generic code which expects cmpxchg there.

  Meanwhile, atomic.h includes cmpxchg.h.

  This causes no noticable damage to the i386 build.

x86_64:

  Move cmpxchg into its own header.  atomic.h already included system.h, so
  this is changed to include cmpxchg.h.

  This is purely cleanup - it's not fixing any warnings - so if the x86_64
  system.h isn't considered as cleanup-worthy as i386, then this can be
  dropped.

  It causes no noticable damage to the x86_64 build.
