2005-04-16[PATCH] ppc64: very basic desktop g5 sound supportBenjamin Herrenschmidt
This patch hacks the current PowerMac Alsa driver to add some basic support of analog sound output to some desktop G5s. 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 Herrenschmidt
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 Herrenschmidt
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).

2005-04-16[PATCH] ppc32: Fix a problem with NTP on !(chrp||gemini)Giovambattista Pulcini
The following problem was found by Giovambattista Pulcini <gpulcini@swintel.it>, who also provided a partial patch, and this has been verified by our time guru Gabriel Paubert <paubert@iram.es>. The problem is that in do_settimeofday() we always set time_state to TIME_ERROR and except on two platforms, never re-set it. This meant that ntp_gettime() and ntp_adjtime() always returned TIME_ERROR, incorrectly. Based on Gabriel's analysis, time_state is used for leap-second processing, and ppc shouldn't be mucking with it.

2005-04-16[PATCH] ppc32: Support 36-bit physical addressing on e500Kumar Gala
To add support for 36-bit physical addressing on e500 the following changes have been made. The changes are generalized to support any physical address size larger than 32-bits: * Allow FSL Book-E parts to use a 64-bit PTE, it is 44-bits of pfn, 20-bits of flags. * Introduced new CPU feature (CPU_FTR_BIG_PHYS) to allow runtime handling of updating hardware register (SPRN_MAS7) which holds the upper 32-bits of physical address that will be written into the TLB. This is useful since not all e500 cores support 36-bit physical addressing. * Currently have a pass through implementation of fixup_bigphys_addr * Moved _PAGE_DIRTY in the 64-bit PTE case to free room for three additional storage attributes that may exist in future FSL Book-E cores and updated fault handler to copy these bits into the hardware TLBs.

2005-04-16[PATCH] ppc32: Allow adjust of pfn offset in pteKumar Gala
Allow the pfn to be offset by more than just PAGE_SHIFT in the pte. Today, PAGE_SHIFT tends to allow us to have 12-bits of flags in the pte. In the future if we have a larger pte we can allocate more bits for flags by offsetting the pfn even further.

CONFIG_PTE_64BIT & CONFIG_PHYS_64BIT are not currently consistently used in the code base. Fixed up the usage such that CONFIG_PTE_64BIT is used when we have a 64-bit PTE regardless of physical address width. CONFIG_PHYS_64BIT is used if the physical address width is larger than 32-bits, regardless of PTE size. These changes required a few sub-arch specific ifdef's to be fixed and the introduction of a physical address format string.

2005-04-16[PATCH] ppc32: Fix pte_update for 64-bit PTEsKumar Gala
While the existing pte_update code handled atomically modifying a 64-bit PTE, it did not return all 64-bits of the PTE before it was modified. This causes problems in some places that expect the full PTE to be returned, like ptep_get_and_clear(). Created a new pte_update function that is conditional on CONFIG_PTE_64BIT. It atomically reads the low PTE word which all PTE flags are required to be in and returns a premodified full 64-bit PTE. Since we now have an explicit 64-bit PTE version of pte_update we can also remove the hack that existed to get the low PTE word regardless of size.

2005-04-16[PATCH] ppc32: Fix AGP and sleep againBenjamin Herrenschmidt
My previous patch that added sleep support for uninorth-agp and some AGP "off" stuff in radeonfb and aty128fb is breaking some configs. More specifically, it has problems with rage128 setups since the DRI code for these in X doesn't properly re-enable AGP on wakeup or console switch (unlike the radeon DRM). This patch fixes the problem for pmac once for all by using a different approach. The AGP driver "registers" special suspend/resume callbacks with some arch code that the fbdev's can later on call to suspend and resume AGP, making sure it's resumed back in the same state it was when suspended. This is platform specific for now. It would be too complicated to try to do a generic implementation of this at this point due to all sort of weird things going on with AGP on other architectures. We'll re-work that whole problem cleanly once we finally merge fbdev's and DRI. In the meantime, please apply this patch which brings back some r128 based laptops into working condition as far as system sleep is concerned.

It fixes various issues related to cpufreq on pmac, including some crashes on some models when sleeping the machine while in low speed, proper voltage control on some newer machines, and adds voltage control on 750FX based G3 laptops.

2005-04-16[PATCH] ppc32: improve timebase sync for SMPPaul Mackerras
Currently the procedure in the ppc32 kernel that synchronizes the timebase registers across an SMP powermac system does so by setting both timebases to zero. That is OK at boot but causes problems if done later. So that we can do hotplug CPU on these machines, this patch changes the code so it reads the timebase from one CPU and transfers the value to the other CPU. (Hotplug CPU is needed for sleep (aka suspend to RAM) to work.)

2005-04-16[PATCH] ppc32: ppc4xx_pic - add acknowledge when enabling level-sensitive IRQEugene Surovegin
This patch adds interrupt acknowledge to the PPC4xx PIC enable_irq implementation for level-sensitive IRQ sources. This helps in cases when enable/disable_irq is used in interrupt handlers for hardware, which requires IRQ acknowledge to be issued from non-interrupt context (e.g. when actual ACK in device needs an I2C transaction). For such strange hardware, interrupt handler disables IRQ and defers actual ACK to some other context. When this happens, IRQ is enabled again. For level-sensitive sources we get spurious triggering right after IRQ is enabled. This patch fixes this. Suggested by Tolunay Orkun <listmember@orkun.us>.

) From: Russell King <rmk+lkml@arm.linux.org.uk> ARM wasn't raising a SIGBUS with a siginfo structure. Fix __do_user_fault() to allow us to use it for SIGBUS conditions, and arrange for the sigbus path to use this. We need to prevent the siginfo code being called if we do not have a user space context to call it, so consolidate the "user_mode()" tests. Thanks to Ian Campbell who spotted this oversight.

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!
