| * MSI: Give archs the option to free all MSI/Xs at once.Michael Ellerman2007-05-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces an optional function, arch_teardown_msi_irqs(), which gives an arch the opportunity to do per-device teardown for MSI/X. If that's not required, the default version simply calls arch_teardown_msi_irq() for each msi irq required. arch_teardown_msi_irqs() is simply passed a pdev, attached to the pdev is a list of msi_descs, it is up to the arch to free the irq associated with each of these as appropriate. For archs that _don't_ implement arch_teardown_msi_irqs(), all msi_descs with irq == 0 are considered unallocated, and the arch teardown routine is not called on them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces an optional function, arch_setup_msi_irqs(), (note the plural) which gives an arch the opportunity to do per-device setup for MSI/X and then allocate all the requested MSI/Xs at once. If that's not required by the arch, the default version simply calls arch_setup_msi_irq() for each MSI irq required. arch_setup_msi_irqs() is passed a pdev, attached to the pdev is a list of msi_descs with irq == 0, it is up to the arch to connect these up to an irq (via set_irq_msi()) or return an error. For convenience the number of vectors and the type are passed also. All msi_descs with irq != 0 are considered allocated, and the arch teardown routine will be called on them when necessary. The existing semantics of pci_enable_msix() are that if the requested number of irqs can not be allocated, the maximum number that _could_ be allocated is returned. To support that, we define that in case of an error from arch_setup_msi_irqs(), the number of msi_descs with irq != 0 are considered allocated, and are counted toward the "max that could be allocated".

| * MSI: Remove dev->first_msi_irqMichael Ellerman2007-05-021-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Now that we keep a list of msi descriptors, we don't need first_msi_irq in the pci dev. If we somehow have zero MSIs configured list_entry() will give us weird oopes or nice memory corruption bugs. So be paranoid. Add BUG_ONs and also a check in pci_msi_check_device() to make sure nvec > 0. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
| * MSI: Use a list instead of the custom link structureMichael Ellerman2007-05-022-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The msi descriptors are linked together with what looks a lot like a linked list, but isn't a struct list_head list. Make it one. The only complication is that previously we walked a list of irqs, and got the descriptor for each with get_irq_msi(). Now we have a list of descriptors and need to get the irq out of it, so it needs to be in the actual struct msi_desc. We use 0 to indicate no irq is setup.

| | | | | | | | | | | | | | | | | | | | | | There are currently several places in the kernel where we kmalloc() a struct pci_dev and start initialising it.

Here is an attempt to clean it all up. In order to find all possibly affected files, I searched for all files including <linux/pci.h> but without any other occurence of "pci" or "PCI". I removed the include statement from all of these, then I compiled an allmodconfig kernel on both i386 and x86_64 and fixed the false positives manually. My tests covered 66% of the affected files, so there could be false positives remaining. Untested files are: arch/alpha/kernel/err_common.c arch/alpha/kernel/err_ev6.c arch/alpha/kernel/err_ev7.c arch/ia64/sn/kernel/huberror.c arch/ia64/sn/kernel/xpnet.c arch/m68knommu/kernel/dma.c arch/mips/lib/iomap.c arch/powerpc/platforms/pseries/ras.c arch/ppc/8260_io/enet.c arch/ppc/8260_io/fcc_enet.c arch/ppc/8xx_io/enet.c arch/ppc/syslib/ppc4xx_sgdma.c arch/sh64/mach-cayman/iomap.c arch/xtensa/kernel/xtensa_ksyms.c arch/xtensa/platform-iss/setup.c drivers/i2c/busses/i2c-at91.c drivers/i2c/busses/i2c-mpc.c drivers/media/video/saa711x.c drivers/misc/hdpuftrs/hdpu_cpustate.c drivers/misc/hdpuftrs/hdpu_nexus.c drivers/net/au1000_eth.c drivers/net/fec_8xx/fec_main.c drivers/net/fec_8xx/fec_mii.c drivers/net/fs_enet/fs_enet-main.c drivers/net/fs_enet/mac-fcc.c drivers/net/fs_enet/mac-fec.c drivers/net/fs_enet/mac-scc.c drivers/net/fs_enet/mii-bitbang.c drivers/net/fs_enet/mii-fec.c drivers/net/ibm_emac/ibm_emac_core.c drivers/net/lasi_82596.c drivers/parisc/hppb.c drivers/sbus/sbus.c drivers/video/g364fb.c drivers/video/platinumfb.c drivers/video/stifb.c drivers/video/valkyriefb.c include/asm-arm/arch-ixp4xx/dma.h sound/oss/au1550_ac97.c I would welcome test reports for these files.

| * pci: New PCI-E reset APIBrian King2007-05-021-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a new API which can be used to issue various types of PCI-E reset, including PCI-E warm reset and PCI-E hot reset. This is needed for an ipr PCI-E adapter which does not properly implement BIST. Running BIST on this adapter results in PCI-E errors. The only reliable reset mechanism that exists on this hardware is PCI Fundamental reset (warm reset). Since driving this type of reset is architecture unique, this provides the necessary hooks for architectures to add this support.

This presents a problem when the new algorithm is not equivalent to the old algorithm. In particular, the new algorithm might only function on top of the existing one.

This is in preparation for templates that may support multiple types of instances depending on what is requested. For example, the planned software async crypto driver will use this construct. For the moment this allows us to check whether the instance constructed is of the correct type and avoid returning success if the type does not match.

| * | [CRYPTO] api: Add async block cipher interfaceHerbert Xu2007-05-021-4/+195
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the frontend interface for asynchronous block ciphers. In addition to the usual block cipher parameters, there is a callback function pointer and a data pointer. The callback will be invoked only if the encrypt/decrypt handlers return -EINPROGRESS. In other words, if the return value of zero the completion handler (or the equivalent code) needs to be invoked by the caller. The request structure is allocated and freed by the caller. Its size is determined by calling crypto_ablkcipher_reqsize(). The helpers ablkcipher_request_alloc/ablkcipher_request_free can be used to manage the memory for a request.

Useful for chips that don't have a built-in I2C controller, additional I2C busses, or testing purposes. To use, include something similar to the following in the board-specific setup code: #include <linux/i2c-gpio.h> static struct i2c_gpio_platform_data i2c_gpio_data = { .sda_pin = GPIO_PIN_FOO, .scl_pin = GPIO_PIN_BAR, }; static struct platform_device i2c_gpio_device = { .name = "i2c-gpio", .id = 0, .dev = { .platform_data = &i2c_gpio_data, }, }; Register this platform_device, set up the I2C pins as GPIO if required and you're ready to go. This will use default values for udelay and timeout, and will work with GPIO hardware that does not support open drain mode, but allows sensing of the SDA and SCL lines even when they are being driven.

| * | i2c-algo-bit: Implement a 50/50 SCL duty cycleJean Delvare2007-05-011-2/+4

While the I2C specification doesn't forbid it, this prevents us from driving the I2C bus to its max speed, limiting us to 66 kbps max on standard I2C busses. Implementing a 50/50 duty cycle instead lets us max out the bandwidth up to the theoretical max of 100 kbps on standard I2C busses. This is particularly important when large amounts of data need to be transfered over the bus, as is the case with some TV adapters when the firmware is being uploaded. In fact this change even allows, at least in theory, fast-mode I2C support at 125, 166 and 250 kbps. There's no way to reach the theoretical max of 400 kbps with this implementation. But I don't think we want to put efforts in that direction anyway: software-driven I2C is very CPU-intensive and bad for latency. Other timing changes: * Don't set SDA high explicitly on error, we're going to issue a stop condition before we leave anyway. * If an error occurs when sending the slave address, yield the CPU before retrying, and remove the additional delay after the new start condition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new helper function to instantiate an i2c device. It is meant as a replacement for i2c_new_device() when you don't know for sure at which address your I2C/SMBus device lives. This happens frequently on TV adapters for example, you know there is a tuner chip on the bus, but depending on the exact board model and revision, it can live at different addresses. So, the new i2c_new_probed_device() function will probe the bus according to a list of addresses, and as soon as one of these addresses responds, it will call i2c_new_device() on that one address. This function will make it possible to port the old i2c drivers to the new model quickly. Signed-off-by: Jean Delvare <khali@linux-fr.org>

| | | | | | | | | | | | | | | | | | | | | | | | Add i2c_bit_add_numbered_bus(), which is equivalent to i2c_bit_add_bus except that it calls i2c_add_numbered_adapter() at the end instead of i2c_add_adapter(). Signed-off-by: Jean Delvare <khali@linux-fr.org>
| * | i2c: Add i2c_add_numbered_adapter()David Brownell2007-05-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a call, i2c_add_numbered_adapter(), registering an I2C adapter with a specific bus number and then creating I2C device nodes for any pre-declared devices on that bus. It builds on previous patches adding I2C probe() and remove() support, and that pre-declaration of devices. This completes the core support for "new style" I2C device drivers. Those follow the standard driver model for binding devices to drivers (using probe and remove methods) rather than a legacy model (where the driver tries to autoconfigure each bus, and registers devices itself).

| * | i2c: Add i2c_board_info and i2c_new_device()David Brownell2007-05-011-0/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides partial support for new-style I2C driver binding. It builds on "struct i2c_board_info" declarations that identify I2C devices on a given board. This is needed on systems with I2C devices that can't be fully probed and/or autoconfigured, such as many embedded Linux configurations where the way a given I2C device is wired may affect how it must be used. There are two models for declaring such devices: * LATE -- using a public function i2c_new_device(). This lets modules declare I2C devices found *AFTER* a given I2C adapter becomes available. For example, a PCI card could create adapters giving access to utility chips on that card, and this would be used to associate those chips with those adapters. * EARLY -- from arch_initcall() level code, using a non-exported function i2c_register_board_info(). This copies the declarations *BEFORE* such an i2c_adapter becomes available, arranging that i2c_new_device() will be called later when i2c-core registers the relevant i2c_adapter. For example, arch/.../.../board-*.c files would declare the I2C devices along with their platform data, and I2C devices would behave much like PNPACPI devices. (That is, both enumerate from board-specific tables.) To match the exported i2c_new_device(), the previously-private function i2c_unregister_device() is now exported. Pending later patches using these new APIs, this is effectively a NOP. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | More update for new style driver support: add a remove() method, and use it in the relevant code paths. Again, nothing will use this yet since there's nothing to create devices feeding this infrastructure.

This patch updates probe() and associated hotplug/coldplug support, but not remove(). Nothing yet _uses_ it to create I2C devices, so those hotplug/coldplug mechanisms will be the only externally visible change. This patch will be an overall NOP since the I2C stack doesn't yet create clients/devices except as part of binding them to legacy drivers. Some code is moved earlier in the source code, helping group more of the per-device infrastructure in one place and simplifying handling per-device attributes. Terminology being adopted: "legacy drivers" create devices (i2c_client) themselves, while "new style" ones follow the driver model (the i2c_client is handed to the probe routine). It's an either/or thing; the two models don't mix, and drivers that try mixing them won't even be registered.

Because the I2C_NAME_SIZE symbol was abused for both i2c_client.name and for i2c_adapter.name, this needed to affect i2c_adapter too. The adapters which used that symbol now use the more-obviously-correct idiom of taking the size of that field. JD: Shorten i2c_adapter.name from 50 to 48 bytes while we're here, to avoid wasting space in padding.

Instead, set the class of i2c_adapter.dev to i2c_adapter_class, so that a symlink will be created for every i2c_adapter in /sys/class/i2c-adapter.
