The C6X IRQ support was copied almost verbatim from the PowerPC virtual IRQ code.

irq_domain_add_simple() was a stop-gap measure until complete irq_domain support was complete. This patch removes the irq_domain_add_simple() interface. This patch also drops the explicit irq_domain initialization performed by the mach-versatile code because the versatile interrupt controller already has irq_domain support built into it. This was a bug that was hanging around quietly for a while, but with the full irq_domain which actually verifies that irq_domain ranges are available it would cause the registration to fail and the system wouldn't boot. v4: Fixed number of irqs in mx5 gpio code v2: Updated to pass in host_data pointer on irq_domain allocation.

This patch removes the simplistic implementation of irq_domains and enables the powerpc infrastructure for all irq_domain users. The powerpc infrastructure includes support for complex mappings between Linux and hardware irq numbers, and can manage allocation of irq_descs. This patch also converts the few users of irq_domain_add()/irq_domain_del() to call irq_domain_add_legacy() instead. v3: Fix bug that set up too many irqs in translation range. v2: Fix removal of irq_alloc_descs() call in gic driver Signed-off-by: NGrant Likely <grant.likely@secretlab.ca> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Milton Miller <miltonm@bga.com> Tested-by: NOlof Johansson <olof@lixom.net>

Add support for a legacy mapping where irq = (hwirq - first_hwirq + first_irq) so that a controller driver can allocate a fixed range of irq_descs and use a simple calculation to translate back and forth between linux and hw irq numbers. This is needed to use an irq_domain with many of the ARM interrupt controller drivers that manage their own irq_desc allocations. Ultimately the goal is to migrate those drivers to use the linear revmap, but doing it this way allows each driver to be converted separately which makes the migration path easier. This patch generalizes the IRQ_DOMAIN_MAP_LEGACY method to use (first_irq-first_hwirq) as the offset between hwirq and linux irq number, and adds checks to make sure that the hwirq number does not exceed range assigned to the controller.

Each revmap type has different arguments for setting up the revmap. This patch splits up the generator functions so that each revmap type can do its own setup and the user doesn't need to keep track of how each revmap type handles the arguments. This patch also adds a host_data argument to the generators. There are cases where the host_data pointer will be needed before the function returns. ie. the legacy map calls the .map callback for each irq before returning. v2: - Add void *host_data argument to irq_domain_add_*() functions - fixed failure to compile - Moved IRQ_DOMAIN_MAP_* defines into irqdomain.c Signed-off-by: NGrant Likely <grant.likely@secretlab.ca> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Milton Miller <miltonm@bga.com> Tested-by: NOlof Johansson <olof@lixom.net>

This patch drops the powerpc-specific irq_map table and replaces it with directly using the irq_alloc_desc()/irq_free_desc() interfaces for allocating and freeing irq_desc structures. This patch is a preparation step for generalizing the powerpc-specific virq infrastructure to become irq_domains. As part of this change, the irq_big_lock is changed to a mutex from a raw spinlock. There is no longer any need to use a spin lock since the irq_desc allocation code is now responsible for the critical section of finding an unused range of irq numbers. The radix lookup table is also changed to store the irq_data pointer instead of the irq_map entry since the irq_map is removed. This should end up being functionally equivalent since only allocated irq_descs are ever added to the radix tree. v5: - Really don't ever allocate virq 0. The previous version could still do it if hint == 0 - Respect irq_virq_count setting for NOMAP. Some NOMAP domains cannot use virq values above irq_virq_count. - Use numa_node_id() when allocating irq_descs. Ideally the API should obtain that value from the caller, but that touches a lot of call sites so will be deferred to a follow-on patch. - Fix irq_find_mapping() to include irq numbers lower than NUM_ISA_INTERRUPTS. With the switch to irq_alloc_desc*(), the lowest possible allocated irq is now returned by arch_probe_nr_irqs(). v4: - Fix incorrect access to irq_data structure in debugfs code - Don't ever allocate virq 0 Signed-off-by: NGrant Likely <grant.likely@secretlab.ca> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Milton Miller <miltonm@bga.com> Tested-by: NOlof Johansson <olof@lixom.net>

This patch drops the powerpc-specific irq_host structures and uses the common irq_domain strucutres defined in linux/irqdomain.h. It also fixes all the users to use the new structure names. Renaming irq_host to irq_domain has been discussed for a long time, and this patch is a step in the process of generalizing the powerpc virq code to be usable by all architecture. An astute reader will notice that this patch actually removes the irq_host structure instead of renaming it. This is because the irq_domain structure already exists in include/linux/irqdomain.h and has the needed data members.

Part of the series to unify the irq remapping mechanisms in the kernel. A follow up patch will copy the powerpc implementation into kernel/irq/irqdomain.c, which will be a lot easier if the structures are identical.

This set of changes are fixing various section mismatch warnings which look to be completely valid. Primerily, those which are fixed are those which can cause oopses by manipulation of driver binding via sysfs. For example: calling code marked __init from driver probe __devinit functions. Some of these changes will be reworked at the next merge window when the underlying reasons are sorted out. In the mean time, I think it's important to have this fixed for correctness. Also included in this set are fixes to various error messages in OMAP - including making them gramatically correct, fixing a few spelling errors, and more importantly, making them greppable by unwrapping them.

Some code - especially the crypto layer - wants to use the x86 FP/MMX/AVX register set in what may be interrupt (typically softirq) context. That *can* be ok, but the tests for when it was ok were somewhat suspect. We cannot touch the thread-specific status bits either, so we'd better check that we're not going to try to save FP state or anything like that. Now, it may be that the TS bit is always cleared *before* we set the USEDFPU bit (and only set when we had already cleared the USEDFP before), so the TS bit test may actually have been sufficient, but it certainly was not obviously so. So this explicitly verifies that we will not touch the TS_USEDFPU bit, and adds a few related sanity-checks. Because it seems that somehow AES-NI is corrupting user FP state. The cause is not clear, and this patch doesn't fix it, but while debugging it I really wanted the code to be more obviously correct and robust.

-
由 Takashi Iwai 提交于
Since 3.2 kernel, the driver starts trying to assign the multi-io DACs before the speaker, thus it assigns DAC2/3 for multi-io and DAC4 for the speaker for a standard laptop setup like a HP, a speaker, a mic-in and a line-in. However, on Acer Aspire 6935, it seems that the speaker pin 0x14 must be connected with either DAC1 or 2; otherwise it results in silence by some reason, although the codec itself allows the routing to DAC3/4. As a workaround, the connection list of each pin is reduced to be mapped to either only DAC1/2 or DAC3/4, so that the compatible assignment as in kernel 3.1 is achieved.

VT1705 codec has two ADCs where the secondary ADC has no MUX but only a fixed connection to the mic pin. This confused the driver and it tries always overriding the input-source selection by assumption of the existing MUX for the secondary ADC, resulted in resetting the input-source at each time PM (including power-saving) occurs. The fix is simply to check the existence of MUX for secondary ADCs in the initialization code.
