This updates the CFQ io scheduler to the new time sliced design (cfq v3). It provides full process fairness, while giving excellent aggregate system throughput even for many competing processes. It supports io priorities, either inherited from the cpu nice value or set directly with the ioprio_get/set syscalls. The latter closely mimic set/getpriority. This import is based on my latest from -mm. Signed-off-by: NJens Axboe <axboe@suse.de> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

I have tweaked this patch slightly to handle an empty list of pages to relocate passed to relocate_new_kernel. And I have added ppc_md.machine_crash_shutdown. To keep up with the changes in the generic kexec infrastructure. From: Albert Herranz <albert_herranz@yahoo.es> The following patch adds support for kexec on the ppc32 platform. Non-OpenFirmware based platforms are likely to work directly without additional changes on the kernel side. The kexec-tools userland package may need to be slightly updated, though. For OpenFirmware based machines, additional work is still needed on the kernel side before kexec support is ready. Benjamin Herrenschmidt is kindly working on that part. In order for a ppc platform to use the kexec kernel services it must implement some ppc_md hooks. Otherwise, kexec will be explicitly disabled, as suggested by benh. There are 3+1 new ppc_md hooks that a platform supporting kexec may implement. Two of them are mandatory for kexec to work. See include/asm-ppc/machdep.h for details. - machine_kexec_prepare(image) This function is called to make any arrangements to the image before it is loaded. This hook _MUST_ be provided by a platform in order to activate kexec support for that platform. Otherwise, the platform is considered to not support kexec and the kexec_load system call will fail (that makes all existing platforms by default non-kexec'able). - machine_kexec_cleanup(image) This function is called to make any cleanups on image after the loaded image data it is freed. This hook is optional. A platform may or may not provide this hook. - machine_kexec(image) This function is called to perform the _actual_ kexec. This hook _MUST_ be provided by a platform in order to activate kexec support for that platform. If a platform provides machine_kexec_prepare but forgets to provide machine_kexec, a kexec will fall back to a reboot. A ready-to-use machine_kexec_simple() generic function is provided to, hopefully, simplify kexec adoption for embedded platforms. A platform may call this function from its specific machine_kexec hook, like this: void myplatform_kexec(struct kimage *image) { machine_kexec_simple(image); } - machine_shutdown() This function is called to perform any machine specific shutdowns, not already done by drivers. This hook is optional. A platform may or may not provide this hook. An example (trimmed) platform specific module for a platform supporting kexec through the existing machine_kexec_simple follows: /* ... */ #ifdef CONFIG_KEXEC int myplatform_kexec_prepare(struct kimage *image) { /* here, we can place additional preparations */ return 0; /* yes, we support kexec */ } void myplatform_kexec(struct kimage *image) { machine_kexec_simple(image); } #endif /* CONFIG_KEXEC */ /* ... */ void __init platform_init(unsigned long r3, unsigned long r4, unsigned long r5, unsigned long r6, unsigned long r7) { /* ... */ #ifdef CONFIG_KEXEC ppc_md.machine_kexec_prepare = myplatform_kexec_prepare; ppc_md.machine_kexec = myplatform_kexec; #endif /* CONFIG_KEXEC */ /* ... */ } The kexec ppc kernel support has been heavily tested on the GameCube Linux port, and, as reported in the fastboot mailing list, it has been tested too on a Moto 82xx ppc by Rick Richardson.

The preempt_count member of struct thread_info is currently either defined as int, unsigned int or __s32 depending on arch. This patch makes the type of preempt_count an int on all archs. Having preempt_count be an unsigned type prevents the catching of preempt_count < 0 bugs, and using int on some archs and __s32 on others is not exactely "neat" - much nicer when it's just int all over. A previous version of this patch was already ACK'ed by Robert Love, and the only change in this version of the patch compared to the one he ACK'ed is that this one also makes sure the preempt_count member is consistently commented.

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.

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.

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.

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.

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.

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.

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.

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.
