2016-09-20powerpc: Remove all usages of NO_IRQMichael Ellerman1-4/+4
NO_IRQ has been == 0 on powerpc for just over ten years (since commit 0ebfff1491ef ("[POWERPC] Add new interrupt mapping core and change platforms to use it")). It's also 0 on most other arches. Although it's fairly harmless, every now and then it causes confusion when a driver is built on powerpc and another arch which doesn't define NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least some of which are to work around that problem. So we'd like to remove it. This is fairly trivial in the arch code, we just convert: if (irq == NO_IRQ) to if (!irq) if (irq != NO_IRQ) to if (irq) irq = NO_IRQ; to irq = 0; return NO_IRQ; to return 0; And a few other odd cases as well. At least for now we keep the #define NO_IRQ, because there is driver code that uses NO_IRQ and the fixes to remove those will go via other trees. Note we also change some occurrences in PPC sound drivers, drivers/ps3, and drivers/macintosh. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells1-1/+1
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

2006-09-23[ALSA] [PPC,SOUND] Fix audio gpio state detectionAndreas Schwab1-2/+3
When booting with line out or headphone plugged, you won't hear anything. The problem is that after reset all channels are muted, but the actual value of the gpio port doesn't exactly match the active_val settings as expected by check_audio_gpio. For example, the line_mute port is set to 7, but check_audio_gpio would expect 0xd or 0xf, thus its return value indicates that it is not active, even though it is. AFAICS only looking at the low bit is enough to determine whether the port is active.

2006-07-03[POWERPC] Add new interrupt mapping core and change platforms to use itBenjamin Herrenschmidt1-4/+4
This adds the new irq remapper core and removes the old one. Because there are some fundamental conflicts with the old code, like the value of NO_IRQ which I'm now setting to 0 (as per discussions with Linus), etc..., this commit also changes the relevant platform and driver code over to use the new remapper (so as not to cause difficulties later in bisecting). This patch removes the old pre-parsing of the open firmware interrupt tree along with all the bogus assumptions it made to try to renumber interrupts according to the platform. This is all to be handled by the new code now. For the pSeries XICS interrupt controller, a single remapper host is created for the whole machine regardless of how many interrupt presentation and source controllers are found, and it's set to match any device node that isn't a 8259. That works fine on pSeries and avoids having to deal with some of the complexities of split source controllers vs. presentation controllers in the pSeries device trees. The powerpc i8259 PIC driver now always requests the legacy interrupt range. It also has the feature of being able to match any device node (including NULL) if passed no device node as an input. That will help porting over platforms with broken device-trees like Pegasos who don't have a proper interrupt tree.

ever since suspend to disk works I had the problem that headphone (un)plugging doesn't get detected properly anymore after the first resume. Reloading the module worked around this ever since, however the real cause of the problem was that after a resume the driver only got interrupts on "unplug" not on "plug". Reactivating the headphone status interrupt in tumbler_resume fixes this.

Ben's patch that shutdowns master switch and restores it after resume ("pmac: Improve sleep code of tumbler driver") isn't enough here on an iBook (snapper chip).

It has severe limitations though: - Only 44100Khz 16 bits - Only work on G5 models using a TAS3004 analog code, that is early single CPU desktops and all dual CPU desktops at this date, but none of the more recent ones like iMac G5. - It does analog only, no digital/SPDIF support at all, no native AC3 support Better support would require a complete rewrite of the driver (which I am working on, but don't hold your breath), to properly support the diversity of apple sound HW setup, including dual codecs, several i2s busses, all the new codecs used in the new machines, proper clock switching with digital, etc etc etc... This patch applies on top of the other PowerMac sound patches I posted in the past couple of days (new powerbook support and sleep fixes). Note: This is a FAQ entry for PowerMac sound support with TI codecs: They have a feature called "DRC" which is automatically enabled for the internal speaker (at least when auto mute control is enabled) which will cause your sound to fade out to nothing after half a second of playback if you don't set a proper "DRC Range" in the mixer. So if you have a problem like that, check alsamixer and raise your DRC Range to something reasonable. Note2: This patch will also add auto-mute of the speaker when line-out jack is used on some earlier desktop G4s (and on the G5) in addition to the headphone jack. If that behaviour isn't what you want, just disable auto-muting and use the manual mute controls in alsamixer.

2005-04-16[PATCH] pmac: Improve sleep code of tumbler driverBenjamin Herrenschmidt1-36/+106
This patch improves the behaviour of the "tumbler/snapper" driver used on newer PowerMacs during sleep. It properly set the HW mutes to shut down amplifiers and does an analog shutdown of the codec. That might improve power consumption during sleep on a number of machines.

2005-04-16[PATCH] pmac: sound support for latest laptopsBenjamin Herrenschmidt1-13/+33
This patch hacks the current Alsa snd-powermac driver to add support for recent machine models with the tas3004 chip, that is basically new laptop models. The Mac Mini is _NOT_ yet supported by this patch (soon soon ...). The G5s (iMac or Desktop) will need the rewritten sound driver on which I'm working on (I _might_ get a hack for analog only on some G5s on the current driver, but no promise).

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
