* [SCSI] BusLogic: make FlashPoint support x86-32 onlyMatthew Wilcox2008-04-071-1/+4
| | | | | | | | | | | We've verified that there are 64 bit and endianness problems in the flashpoint driver. Reverse the logic of CONFIG_OMIT_FLASHPOINT (make it CONFIG_SCSI_FLASHPOINT) and make it depend on X86_32 so it can't appear for any other architectures. Long term, if someone chooses, they could make FlashPoint 64 bit compliant (it looks like its a question of fixing up the sizes in some of the packed descriptors) Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* [SCSI] remove use_sg_chainingJames Bottomley2008-01-301-1/+0
| | | | | | | | | | | With the sg table code, every SCSI driver is now either chain capable or broken (or has sg_tablesize set so chaining is never activated), so there's no need to have a check in the host template. Also tidy up the code by moving the scatterlist size defines into the SCSI includes and permit the last entry of the scatterlist pools not to be a power of two.

* [SCSI] add use_sg_chaining option to scsi_host_templateFUJITA Tomonori2007-10-161-0/+1
| | | | | | | | | | This option is true if a low-level driver can support sg chaining. This will be removed eventually when all the drivers are converted to support sg chaining. q->max_phys_segments is set to SCSI_MAX_SG_SEGMENTS if false.

* [SCSI] BusLogic: stop using check_regionZachary Amsden2007-04-171-25/+48
| | | | | | | | | | | | I got so sick of seing the check_region warnings from BusLogic.c I actually fixed it properly. Never use check region, reserve it before the probe with request region instead and check the error result; free region if setup fails. Should be functionally identical to the original except for fixing the potential race.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [SCSI] Pass proper device from BusLogic to SCSI layerPetr Vandrovec2006-01-121-1/+2
| | | | | | | | | | | | | | | | | | | | | | While trying to get SUSE's SLES9 working on system with more than 4GB we've noticed that SCSI layer happilly passes addresses over 4GB to the buslogic driver, which is quite a big problem as buslogic can generate only 32bit busmastering cycles. Fortunately in the current kernels this problem does not exist anymore as SCSI layer now assumes 4GB capable device by default, but it is still good idea to pass correct device structure to the SCSI layer. If nothing else, /sys/block/sda/device now points to /sys/devices/pci0000:00/0000:00:10.0/host0/... instead of /sys/devices/platform/host0/... like it did in the past. Change does nothing for ISA based BusLogic adapters, they'll still end under platform (and they are probably broken for long time as I do not see anything forcing ISA 16MB limit for them).

| | | | | | | | | | | | | scsi_cmnd->serial_number_at_timeout doesn't serve any purpose anymore. All serial_number == serial_number_at_timeout tests are always true in abort callbacks. Kill the field. Also, as ->pid always equals ->serial_number and ->serial_number doesn't have any special meaning anymore, update comments above ->serial_number accordingly. Once we remove all uses of this field from all lldd's, this field should go. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+3574
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!
