2006-11-01[PATCH] ahci: fix status register check in ahci_softresetTejun Heo1-2/+1
ahci_softreset() used to use ahci_tf_read() which reads D2H_REG area to check for the Status register. However, this area is zeroed on initialization and not set by initial signature FIS. Replace it with ahci_check_status(). This bug prevented CLO code from being activated whenever BSY and/or DRQ is set prior to softreset. This fix makes AHCI_FLAG_RESET_NEEDS_CLO flag redundant.

2006-10-31[PATCH] ata_piix: allow 01b MAP for both ICH6M and ICH7MTejun Heo1-32/+5
ICH7M was separated from ICH6M to allow undocumented MAP value 01b which was spotted on an ASUS notebook. However, there is also notebooks with MAP value 01b on ICH6M. This patch re-merges ICH6M and ICH7M entries and allows MAP value 01b for both. This problem has been reported and initial patch provided by Jonathan Dieter.

2006-10-31[PATCH] sata_sis: fix flags handling for the secondary portTejun Heo1-11/+10
sis_init_one() modifies probe_ent->port_flags after allocating and initializing it using ata_pci_init_native_mode(). This makes port_flags for the secondary port (probe_ent->pinfo2->flags) go out of sync resulting in misdetection of device due to incorrectly initialized SCR access flag. This patch make probe_ent alloc/init happen after the final port flags value is determined. This is fragile but probe_ent and all the related mess are scheduled to go away soon for exactly this reason. We just need to hold everything together till then. This has been spotted and diagnosed and tested by Patrick McHardy.

There are some Linux supported platforms that simply cannot hit the low I/O addresses used by ATA legacy mode PCI mappings. These platforms have a window for PCI space that is fixed by the board logic and doesn't include the neccessary locations.

2006-10-21[PATCH] libata: use correct map_db values for ICH8Kristen Carlson Accardi1-2/+2
Use valid values for ICH8 map_db. With the old values, when the controller was in Native mode, and SCC was 1 (drives configured for IDE), any drive plugged into a slave port was not recognized. For Combined Mode (and SCC is still 1), 2 is a value value for MAP.map_value, and needs to be recognized.

2006-10-11[PATCH] libata: return sense data in HDIO_DRIVE_CMD ioctlEran Tromer1-7/+39
Make the HDIO_DRIVE_CMD ioctl in libata (ATA command pass through) return a few ATA registers to userspace, following the same convention as the drivers/ide implementation of the same ioctl. This is needed to support ATA commands like CHECK POWER MODE, which return information in nsectors. This fixes "hdparm -C" on SATA drives. Forcing the sense data read via the cc flag causes spurious check conditions, so we filter these out (following the ATA command pass-through specification T10/04-262r7).

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells11-37/+24
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.
