* [SCSI] aic79xx: use dma_get_required_mask()Hannes Reinecke2007-02-10
| | | | | | | | | | | | | | | | | As originally noted by Frederic Temporelli, the aic79xx supports 64 bit addressing, but the initialization code of the driver is wrong: it tests the available memory size instead of testing the maximum available memory address. This patch uses the correct dma_get_required_mask() macros to determine the correct addressing method.

* [SCSI] aic79xx: Fixup external device resetHannes Reinecke2006-10-25
| | | | | | | | | | | | | | | Whenever an external device is resetted we really have to take care to keep the channel in sync. Just notifying SCSI-ML and retry is not enough as we have to make sure the SCSI bus is not getting confused, either. So whenever we detect an external reset we rewrite the command to TUR, disable packetized command and notify the internal engine that an abort has happened. This way we trigger a proper bus reset sequence and all devices will be renegotiated properly. Kudos to Justin Gibbs and Luben Tuikov for this idea.

* 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.

* | [PATCH] EISA bus MODALIAS attributes supportMichael Tokarev2006-09-27
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add modalias attribute support for the almost forgotten now EISA bus and (at least some) EISA-aware modules. The modalias entry looks like (for an 3c509 NIC): eisa:sTCM5093 and the in-module alias like: eisa:sTCM5093* The patch moves struct eisa_device_id declaration from include/linux/eisa.h to include/linux/mod_devicetable.h (so that the former now #includes the latter), adds proper MODULE_DEVICE_TABLE(eisa, ...) statements for all drivers with EISA IDs I found (some drivers already have that DEVICE_TABLE declared), and adds recognision of __mod_eisa_device_table to scripts/mod/file2alias.c so that proper modules.alias will be generated. There's no support for /lib/modules/$kver/modules.eisamap, as it's not used by any existing tools, and because with in-kernel modalias mechanism those maps are obsolete anyway. The rationale for this patch is: a) to make EISA bus to act as other busses with modalias support, to unify driver loading b) to foget about EISA finally - with this patch, kernel (who still supports EISA) will be the only one who knows how to choose the necessary drivers for this bus ;) [akpm@osdl.org: fix the kbuild bit] Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Randy Dunlap <rdunlap@xenotime.net> Acked-the-net-bits-by: Jeff Garzik <jeff@garzik.org> Acked-the-tulip-bit-by: Valerie Henson <val_henson@linux.intel.com> Cc: James Bottomley <James.Bottomley@steeleye.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even with the latest fixes aic79xx still occasionally triggers the BUG_ON in slave_destroy. Rather than trying to figure out the various levels of interaction here I've decided to remove the callback altogether. The primary reason for the slave_alloc / slave_destroy is to keep an index of pointers to the sdevs associated with a given target. However, by changing the arguments to the affected functions slightly it's possible to avoid the use of that index entirely. The only performance penalty we'll incur is in writing the information for /proc/scsi/XXX, as we'll have to recurse over all available sdevs to find the correct ones. But I doubt that reading from /proc is in any way time-critical. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
