2007-10-12[SCSI] advansys: Remove library-style callback routinesMatthew Wilcox
Convert adv_isr_callback, adv_async_callback and asc_isr_callback into direct calls. Remove the unused asc_exe_callback. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-12[SCSI] advansys: Move struct device out of the cfg structuresMatthew Wilcox
The cfg structures are supposed to be disposable after initialisation; with the 'dev' used for DMA mapping in there, that's not possible. Move the dev to the board. Also inline AscInitFromAscDvcVar into its only caller, remove some unnecessary prototypes and sort out a few minor formatting issues.

2007-10-12[SCSI] advansys: Stop using n_io_port in Scsi_Host structureMatthew Wilcox
n_io_port isn't suitable for advansys because some of the boards have more than 255 bytes of io port space. There's already a driver-private replacement, asc_n_io_port, but for some reason the driver was still setting and occasionally reporting n_io_port.

2007-10-12[SCSI] advansys: ioremap no longer needs page-aligned addressesMatthew Wilcox
At some point during Linux 2.1 development, ioremap() gained the ability to handle addresses which weren't page-aligned. Also expand the CONFIG_PCI range to encompass that entire section of wide board initialisation, since all wide boards are PCI.

2007-10-12[SCSI] advansys: delete AscGetChipBusTypeMatthew Wilcox
By moving a test from AscGetChipBusType into its only caller, we can delete the whole function Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-12[SCSI] advansys: misc reformattingMatthew Wilcox
Remove some useless forward declarations Reformat some comments, debug messages, and the occasional piece of real code Removal of unnecessary braces Remove duplicate setting of shost->irq Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-12[SCSI] advansys: remove INQUIRY sniffingMatthew Wilcox
Use slave_configure() to do all the work that used to be done in AscInquiryHandling and AdvInquiryHandling. Split slave_configure into two functions, one for wide and one for narrow controllers. Remove some unused definitions, duplicate definitions, unnecessary declarations, and scsireqq, cap_info and inquiry from struct asc_board.

2007-10-12[SCSI] advansys: More PCI cleanupsMatthew Wilcox
- Remove wrappers around the PCI configuration space accessors - Call pci_set_master() instead of poking at config space directly - Move the latency setting into one function called for both narrow and wide boards. - Tidy up AdvInitGetConfig() a little. - Delete a few unused prototypes and definitions. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-12[SCSI] advansys: Update resource managementMatthew Wilcox
Make sure the resources are reserved and released by all the callers of advansys_board_found(). This eliminates the check_region-style race. It also allows us to use the pci_request_regions() API. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-12[SCSI] advansys: Convert to ISA driver modelMatthew Wilcox
Register two isa_drivers, one for ISA and one for VLB, in order to preserve detection order. When deleting advansys_detect, we lose the last vestiges of the code that limited IO port scanning. This code has been effectively disabled for many years anyway; I'll restore it in a module_param later. We also lose the code that placed all ISA PnP cards into WaitForKey state -- drivers shouldn't be doing this anyway. The asc_host array goes away too. Also remove some IOADR and other definitions, such as ASC_NUM_BOARD_SUPPORTED. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-12[SCSI] advansys: Convert to EISA driver modelMatthew Wilcox
- Switch EISA probing to the driver model - Remove some now-unused macros and functions - Update the FIXME now that we use the correct driver model probing API Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-12[SCSI] advansys: Convert to PCI driver modelMatthew Wilcox
- Add a pci_driver interface for the PCI advansys devices (for ISA/EISA/VLB devices, we still call advansys_detect). - Many functions are converted from __init to __devinit to allow hotplug PCI to work. - Only keep devices found by advansys_detect in the asc_host list. - Rename asc_board_count to asc_legacy_count. New asc_board_count is only used to generate a unique name for each device. - Remove some now-unused macros and struct definitions Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-12[SCSI] advansys: Move to scsi hotplug initialisation modelMatthew Wilcox
- Switch from scsi_register/scsi_unregister to scsi_host_alloc, scsi_add_host, scsi_scan_host and scsi_host_put. - Rename the scsi_host_template to advansys_template - Use module_init and module_exit instead of scsi_module.c - Remove protection against advansys_detect being called twice Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-12[SCSI] advansys: Make advansys_board_found a little more readableMatthew Wilcox
- Put all the error cleanup at the end of the function and goto the appropriate label - Split advansys_wide_init_chip out of advansys_board_found - Split advansys_wide_free_mem out of advansys_board_found. Use it from advansys_release - Use GFP_KERNEL, not GFP_ATOMIC, when allocating memory during initialisation - Eliminate lots of PROC_FS ifdefs by removing the ifdefs around the prtbuf struct member Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-12[SCSI] advansys: Stop checking the scsi_cmnd belongs to our Scsi_HostMatthew Wilcox
The interrupt routines used to walk the list of Scsi_Hosts belonging to this driver to make sure that the scsi_cmnd belonged to one of them. This is a waste of time and gets in the way of later cleanups, so delete it. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-12[SCSI] advansys: Improve interrupt handlerMatthew Wilcox
Pass the Scsi_Host to the interrupt handler, rather than polling all hosts for each interrupt. Return IRQ_NONE if we didn't handle this interrupt Don't set the IRQF_DISABLED flag; this is not a fast-executing interrupt handler.

2007-10-12[SCSI] advansys: Clean up proc_info implementationMatthew Wilcox

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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.

2005-08-08[SCSI] add global timeout to the scsi mid-layerJames Bottomley
There are certain rogue devices (and the aic7xxx driver) that return BUSY or QUEUE_FULL forever. This code will apply a global timeout (of the total number of retries times the per command timer) to a given command. If it is exceeded, the command is completed regardless of its state. The patch also removes the unused field in the command: timeout and timeout_total. This solves the problem of detecting an endless loop in the mid-layer because of BUSY/QUEUE_FULL bouncing, but will not recover the device. In the aic7xxx case, the driver can be recovered by sending a bus reset, so possibly this should be tied into the error handler? Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
