2008-11-15[SCSI] dpt_i2o: fix transferred data length for scsi_set_resid()Miquel van Smoorenburg
dpt_i2o.c::adpt_i2o_to_scsi() reads the value at (reply+5) which should contain the length in bytes of the transferred data. This would be correct if reply was a u32 *. However it is a void * here, so we need to read the value at (reply+20) instead. The value at (reply+5) is usually 0xff0000, which is apparently 'large enough' and didn't cause any trouble until 2.6.27 where commit 427e59f09fdba387547106de7bab980b7fff77be Author: James Bottomley <James.Bottomley@HansenPartnership.com> Date: Sat Mar 8 18:24:17 2008 -0600 [SCSI] make use of the residue value caused this to become visible through e.g. iostat -x .

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.

2006-01-14[SCSI] I2O: move pci_request_regions() just behind pci_enable_device()Salyzyn, Mark
The problem in dpt_i2o could be the pci config space accesses it triggers as it loads, dangerous to do if there is any I/O activity going on in the other driver (probable if a boot driver I guess). I approve this patch to dpt_i2o.c, and am applying it to the Adaptec branch of the driver. Thanks for the investigation Ryoji. --- In linux 2.6.15, data transfer does hang when both dpt_i2o and i2o_block drivers are loaded. It seems that location of pci_request_regions() are wrong.

Originally From: Andrew Morton <akpm@osdl.org> Altered By: "Salyzyn, Mark" <mark_salyzyn@adaptec.com> There is an additional 'build fix' patch that Andrew Morton submitted on the kernel list (I have changed out his dpr_i2o with dpt_i2o below though).

2005-08-08[SCSI] Bug 4940 Repeatable Kernel Panic on Adaptec 2015S I20 device on bootupJames Bottomley
From: "Salyzyn, Mark" <mark_salyzyn@adaptec.com> Prevent driver from loading if another driver (i2o) has already claimed the resources associated with the card. Discussion associated with this bug can be referenced at http://bugzilla.kernel.org/show_bug.cgi?id=4940 where it was agreed to use pci_request_regions in both the dpt_i2o and the i2o driver to prevent both drivers loading on the same adapter(s).

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!
