* [PATCH] ppc32: add 405EP cpu_spec entryEugene Surovegin2005-06-08

Recent change to arch/ppc/kernel/misc.S ("Fix incorrect CPU_FTR fixup usage for unified caches") triggered this bug and 405EP boards don't boot anymore.

* [PATCH] ppc32: Fix incorrect CPU_FTR fixup usage for unified cachesKumar Gala2005-06-06
| | | | | | | | | | | | Runtime feature support for unified caches was testing a userland feature flag (PPC_FEATURE_UNIFIED_CACHE) instead of a cpu feature flag (CPU_FTR_SPLIT_ID_CACHE). Luckily the current defined bit mask for cpu features and userland features do not overlap so this only causes an issue on machines with a unified cache, which is extremely rare on PPC today.

* [PATCH] ppc32: MPC834x BCSR_SIZE too small for use in a BAT.Kumar Gala2005-05-28
| | | | | | | | | | | | The call to io_block_mapping was creating an invalid BAT entry because the value of BCSR_SIZE (32K) is too small to be used in a BAT (128K min).

* [PATCH] ppc32: Simplified load string emulation error checkingKumar Gala2005-05-28
| | | | | | | | | | | | | | | | The error checking for emulation of load string instructions was overly generous and would cause certain valid forms of the instructions to be treated as illegal. We drop the range checking since the architecture allows this to be boundedly undefined. Tests on CPUs that support these instructions appear not do cause illegal instruction traps on range errors and just allow the execution to occur. Thanks to Kim Phillips for debugging this and figuring out what real HW was doing.

* [PATCH] ppc32: Fix cpufreq vs. sleep issueBenjamin Herrenschmidt2005-05-28
| | | | | | | | | | | | | | | | | | | Recent kernels occasionally trigger a PMU timeout on some mac laptops, typically on wakeup from sleep. This seem to be caused by either a too big latency caused by the cpufreq switch on wakeup from sleep or by an interrupt beeing lost due to the reset of the interrupt controller done during wakeup. This patch makes that code more robust by stopping PMU auto poll activity around cpufreq changes on machines that use the PMU for such changes (long latency switching involving a CPU hard reset and flush of all caches) and by removing the reset of the open pic interrupt controller on wakeup (that can cause the loss of an interrupt and Darwin doesn't do it, so it must not be necessary).

* [PATCH] ppc32: don't call progress functions after bootPaul Mackerras2005-05-20
| | | | | | | | | | | | | | | On ppc32, the platform code can supply a "progress" function that is used to show progress through the boot. These functions are usually in an init section and so can't be called after the init pages are freed. Now that the cpu bringup code can be called after the system is booted (for hotplug cpu) we can get the situation where the progress function can be called after boot. The simple fix is to set the progress function pointer to NULL when the init pages are freed, and that is what this patch does (note that all callers already check whether the function pointer is NULL before trying to call it).

| | | | | | | | | | | | | | | The PPC32 kernel puts platform-specific functions into separate sections so that unneeded parts of it can be freed when we've booted and actually worked out what we're running on today.

* [PATCH] ISA DMA Kconfig fixes - part 1Al Viro2005-05-04
| | | | | | | | | | | | | | | | | | | | A bunch of drivers use ISA DMA helpers or their equivalents for platforms that have ISA with different DMA controller (a lot of ARM boxen). Currently there is no way to put such dependency in Kconfig - CONFIG_ISA is not it (e.g. it is not set on platforms that have no ISA slots, but have on-board devices that pretend to be ISA ones). New symbol added - ISA_DMA_API. Set when we have functional enable_dma()/set_dma_mode()/etc. set of helpers. Next patches in the series will add missing dependencies for drivers that need them. I'm very carefully staying the hell out of the recurring flamefest on what exactly CONFIG_ISA would mean in ideal world - added symbol has a well-defined meaning and for now I really want to treat it as completely independent from the mess around CONFIG_ISA.

* [PATCH] ppc64: very basic desktop g5 sound supportBenjamin Herrenschmidt2005-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
