* [PATCH] ppc32: Clean up NUM_TLBCAMS usage for Freescale Book-E PPC'sKumar Gala2005-06-21
| | | | | | | | | | | Made the number of TLB CAM entries private and converted the board consumers to use num_tlbcam_entries which is setup at boot time from configuration registers. This way the only consumers of the #define NUM_TLBCAMS are the arrays used to manage the TLB.

* [PATCH] ppc32: Added support for all MPC8548 internal interruptsKumar Gala2005-06-21
| | | | | | | | | | | | | | | | | The MPC8548 has 48 internal interrupts and 12 external interrupts. The previous generation PowerQUICC III devices only had 32 internal and 12 external interrupts on the primary interrupt controller. Expanded the number of internal interrupts to 48 for all PowerQUICC III processors and moved the interrupt numbers for the external after the 48 internal interrupt lines, rather than putting the 12 new internal interrupts at the end and ifdef'ng the whole mess. As parted of this created a macro which represents the internal interrupt senses since they are the same on all PQ3 processors.

* [PATCH] smp_processor_id() cleanupIngo Molnar2005-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements a number of smp_processor_id() cleanup ideas that Arjan van de Ven and I came up with. The previous __smp_processor_id/_smp_processor_id/smp_processor_id API spaghetti was hard to follow both on the implementational and on the usage side. Some of the complexity arose from picking wrong names, some of the complexity comes from the fact that not all architectures defined __smp_processor_id. In the new code, there are two externally visible symbols: - smp_processor_id(): debug variant. - raw_smp_processor_id(): nondebug variant. Replaces all existing uses of _smp_processor_id() and __smp_processor_id(). Defined by every SMP architecture in include/asm-*/smp.h. There is one new internal symbol, dependent on DEBUG_PREEMPT: - debug_smp_processor_id(): internal debug variant, mapped to smp_processor_id(). Also, i moved debug_smp_processor_id() from lib/kernel_lock.c into a new lib/smp_processor_id.c file. All related comments got updated and/or clarified. I have build/boot tested the following 8 .config combinations on x86: {SMP,UP} x {PREEMPT,!PREEMPT} x {DEBUG_PREEMPT,!DEBUG_PREEMPT} I have also build/boot tested x64 on UP/PREEMPT/DEBUG_PREEMPT. (Other architectures are untested, but should work just fine.)

| * [PATCH] AGP fix for Xen VMMKeir Fraser2005-06-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When Linux is running on the Xen virtual machine monitor, physical addresses are virtualised and cannot be directly referenced by the AGP GART. This patch fixes the GART driver for Xen by adding a layer of abstraction between physical addresses and 'GART addresses'. Architecture-specific functions are also defined for allocating and freeing the GATT. Xen requires this to ensure that table really is contiguous from the point of view of the GART. These extra interface functions are defined as 'no-ops' for all existing architectures that use the GART driver.

| | | | | | | | | | | | | | | | | | | | | | | | This patch adds on-chip PCI bridge support for the PQ2 family. The incomplete existent code is updated with interrupt handling stuff and board-specific bits for 8272ADS and PQ2FADS; the related files were renamed (from m8260_pci to m82xx_pci) to be of more generic fashion.

| | | | | | | | | | | | The clock spreading disable/enable code was called to late/early during the suspend/resume code on some laptops and would trigger a might_sleep() warning due to the down() call in the low level i2c code.

* [PATCH] move SA_xxx defines to linux/signal.hStas Sergeev2005-05-01
| | | | | | | | | | | | | | | | | | | The attached patch moves the IRQ-related SA_xxx flags (namely, SA_PROBE, SA_SAMPLE_RANDOM and SA_SHIRQ) from all the arch-specific headers to linux/signal.h. This looks like a left-over after the irq-handling code was consolidated. The code was moved to kernel/irq/*, but the flags are still left per-arch. Right now, adding a new IRQ flag to the arch-specific header, like this patch does: http://cvs.sourceforge.net/viewcvs.py/*checkout*/alsa/alsa-driver/utils/patches/pcsp-kernel-2.6.10-03.diff?rev=1.1 no longer works, it breaks the compilation for all other arches, unless you add that flag to all the other arch-specific headers too.

* [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.

* [PATCH] ppc32: Support 36-bit physical addressing on e500Kumar Gala2005-04-16
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] ppc32: Allow adjust of pfn offset in pteKumar Gala2005-04-16
| | | | | | | | | | | 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.

* [PATCH] ppc32: Fix pte_update for 64-bit PTEsKumar Gala2005-04-16
| | | | | | | | | | | | | | | | | | 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.

* [PATCH] ppc32: Fix AGP and sleep againBenjamin Herrenschmidt2005-04-16
| | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
