2008-01-31[ALSA] snd-powermac: handle dead DMA transfersT. H. Huth1-5/+102
This patch provides the snd-powermac sound driver with the ability to handle dead DMA transfers. If a dead DMA transfer is detected, the driver now sets up a new DMA transfer to continue with the sound output at the point where the old transfer died. This dead DMA transfer handling has become necessary with recent kernels on certain G4 PowerMacs. Please refer to the following URLs for more information: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3126 https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/87652 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=436723 The patch is based on the dead DMA transfer handling code from the old dmasound driver which can be found in the file sound/oss/dmasound/dmasound_awacs.c in the Linux source code.

2007-06-19[POWERPC] Fix snd-powermac refcounting bugsBenjamin Herrenschmidt1-3/+5
The old snd-powermac driver has some serious refcounting issues when initialisation fails, which is the case on all new machines with a layout-id since those are handled by the new snd-aoa driver. Some of those bugs seem to have been under the radar for some time (like double pci_dev_put), but one was actually added in 2.6.22 with Stephen attempt at teaching refcounting to the driver which didn't do it at all. This patch fixes both, thus removing all sort of kref errors that would happen if that driver gets loaded on a G5 machine or a recent PowerBook due to OF nodes left around with a 0 refcount.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2-4/+4
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.

This patch makes snd-powermac load when it can't bind the device right away. That's the expected behaviour for hotplugging, but fixes an important problem I was seeing with doing a modprobe snd-powermac with a version that refuses loading on machines with layout-id: snd-powermac would create a bunch of uevents and then refuse to load, the uevents causing udev to reload it again, ad eternum.

2006-07-03[POWERPC] Add new interrupt mapping core and change platforms to use itBenjamin Herrenschmidt2-23/+18
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.

2006-07-02[PATCH] powermac: Fix some 64b resource damageBenjamin Herrenschmidt1-1/+1
The 64 bits resource patches did a bit of damage on PowerMac causing a buffer overflow in macio_asic and a warning in a sound driver. The former is fixed by reverting the sprintf of the bus_id to %08x as it was before. The bus_id used for macio devices is always a 32 bits value (macio always sits in 32 bits space) and since it's exposed to userland, the format of the string shouldn't be changed like that anyway.
