* [PATCH] libata: move ata_irq_on() into libata-sff.cTejun Heo2006-12-01
| | | | | | | | | | ata_irq_on() isn't used outside of libata core layer. The function is TF/SFF interface specific but currently used by core path with some hack too. Move it from include/linux/libata.h to drivers/ata/libata-sff.c. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] libata: handle 0xff status properlyTejun Heo2006-12-01
| | | | | | | | | | | | | | | | | | | | libata waits for !BSY even when the status register reports 0xff. This causes long boot delays when D8 isn't pulled down properly. This patch does the followings. * don't wait if status register is 0xff in all wait functions * make ata_busy_sleep() return 0 on success and -errno on failure. -ENODEV is returned on 0xff status and -EBUSY on other failures. * make ata_bus_softreset() succeed on 0xff status. 0xff status is not reset failure. It indicates no device. This removes unnecessary retries on such ports. Note that the code change assumes unoccupied port reporting 0xff status does not produce valid device signature.

* [PATCH] sata_nv ADMA/NCQ support for nForce4Robert Hancock2006-12-01
| | | | | | | | | | | | | | | | | | | | | This patch adds support for ADMA mode on NVIDIA nForce4 (CK804/MCP04) SATA controllers to the sata_nv driver. Benefits of ADMA mode include: - NCQ support - Reduced CPU overhead (controller DMAs command information from memory instead of them being pushed in by the CPU) - Full 64-bit DMA support ADMA mode is enabled by default in this version. To disable it, set the module parameter adma_enabled=0.

* [PATCH] ahci: ignore PORT_IRQ_IF_ERR on JMB controllersTejun Heo2006-11-29
| | | | | | | | | | | | | | | JMicron AHCI controllers set PORT_IRQ_IF_ERR on device errors. The IRQ status bit indicates interface error or protocol mismatch and ahci driver interprets it into AC_ERR_ATA_BUS. So, whenever an ATAPI device raises check condition, ahci interprets it as ATA bus error and thus resets it which, in turn, raises check condition thus creating a reset loop and rendering the device unuseable. This patch makes JMB controllers ignore PORT_IRQ_IF_ERR when interpreting error condition. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Justin Tsai <justin@jmicron.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A curious thing happens, however, when ata_qc_new_init fails to get an ata_queued_cmd: First, ata_qc_new_init handles the failure like this: cmd->result = (DID_OK << 16) | (QUEUE_FULL << 1); done(cmd); Then, we return to ata_scsi_translate and do this: err_mem: cmd->result = (DID_ERROR << 16); done(cmd); It appears to me that first we set a status code indicating that we're ok but the device queue is full and finish the command, but then we blow away that status code and replace it with an error flag and finish the command a second time! That does not seem to be desirable behavior since we merely want the I/O to wait until a command slot frees up, not send errors up the block layer. In the err_mem case, we should simply exit out of ata_scsi_translate instead. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

|/ | | | | | | | | | | | | | | | When building a monolithic kernel, the load order of drivers does not work for SAS libata users, resulting in a kernel oops. Convert libata to use subsys_initcall instead of module_init, which ensures that libata gets loaded before any LLDD. This is the same thing that scsi core does to solve the problem.

This patch make probe_ent alloc/init happen after the final port flags value is determined.

| * IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.
