* [PATCH] getting rid of all casts of k[cmz]alloc() callsRobert P. J. Day2006-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Run this: #!/bin/sh for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do echo "De-casting $f..." perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f done And then go through and reinstate those cases where code is casting pointers to non-pointers. And then drop a few hunks which conflicted with outstanding work.

* [PATCH] HPT37x: read f_CNT saved by BIOS from portSergei Shtylyov2006-12-13
| | | | | | | | | | | | | The undocumented register BIOS uses for saving f_CNT seems to only be mapped to I/O space while all the other HPT3xx regs are dual-mapped. Looks like another HighPoint's dirty trick. With this patch, the deadly kernel oops on the cards having the modern HighPoint BIOSes is now at last gone!

* [PATCH] ide: fix HPT3xx hotswap supportSergei Shtylyov2006-12-13
| | | | | | | | | | | | | | | | | Fix the broken hotswap code: on HPT37x it caused RESET- to glitch when tristating the bus (the MISC control 3/6 and soft control 2 need to be written to in the certain order), and for HPT36x the obsolete HDIO_TRISTATE_HWIF ioctl() handler was called instead which treated the state argument wrong. Also, get rid of the soft control reg. 1 wtite to enable IDE interrupt -- this is done in init_hpt37x() already... Have been tested on HPT370 and 371N.

* [PATCH] ide: optimize HPT37x timing tablesSergei Shtylyov2006-12-13
| | | | | | | | | | | | | | | | | Save some space on the timing tables by introducing the separate transfer mode table in which the mode lookup is done to get the index into the timing table itself. Get rid of the rest of the obsolete/duplicate tables and use one set of tables for the whole HPT37x chip family like the HighPoint open-source drivers do. Documnent the different timing register layout for the HPT36x chip family (this is my guesswork based on the timing values). Have been tested and works fine on HPT370/302/371N.

* [PATCH] ide: fix HPT37x timing tablesSergei Shtylyov2006-12-13
| | | | | | | | | | | | | | | | | | | Fix/remove bad/unused timing tables: HPT370/A 66 MHz tables weren't really needed (the chips are not UltraATA/133 capable and shouldn't support 66 MHz PCI) and had many modes over- and underclocked, HPT372 33 MHz table was in fact for 66 MHz and 50 MHz table missed UltraDMA mode 6, HPT374 33 MHz table was really for 50 MHz... (Actually, HPT370/A 33 MHz tables also have issues. e.g. HPT370 has PIO modes 0/1 overlocked.) There's also no need in the separate HPT374 tables because HPT372 timings should be the same (and those tables has UltraDMA mode 6 which HPT374 supports depending on HPT374_ALLOW_ATA133_6 #define)...

* [PATCH] ide: HPT3xxN clocking fixesSergei Shtylyov2006-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix serious problems with the HPT372N clock turnaround code: - the wrong ports were written to when called for the secondary channel; - it didn't serialize access to the channels; - turnaround shou;dn't be done on 66 MHz PCI; - caching the clock mode per-channel caused it to get out of sync with the actual register value. Additionally, avoid calibrating PLL twice (for each channel) as the second try results in a wrong PCI frequency and thus in the wrong timings. Make the driver deal with HPT302N and HPT371N correctly -- the clocking and (seemingly) a need for clock tunaround is the same as for HPT372N. HPT371/N chips have only one, secondary channel, so avoid touching their "pure virtual" primary channel, and disable it if the BIOS haven't done this already. Also, while at it, disable UltraATA/133 for HPT372 by default -- 50 MHz DPLL clock don't allow for this speed anyway. And remove the traces of the former bad patch that wasn't even applicable to this version of driver. Has been tested on HPT370/371N, unfortunately I don't have an instant access to the other chips...

| | | | | | | | | | | | | | | | | | While working on bidi support at struct request level I have found that blk_queue_activity_fn is actually never used. The only user is in ide-probe.c with this code: /* enable led activity for disk drives only */ if (drive->media == ide_disk && hwif->led_act) blk_queue_activity_fn(q, hwif->led_act, drive); And led_act is never initialized anywhere. (Looking back at older kernels it was used in the PPC arch, but was removed around 2.6.18) Unless it is all for future use off course.

* [PATCH] ide-cd: Handle strange interrupt on the Intel ESB2Alan Cox2006-12-10
| | | | | | | | | | | | | | | | The ESB2 appears to emit spurious DMA interrupts when configured for native mode and handling ATAPI devices. Stratus were able to pin this bug down and produce a patch. This is a rework which applies the fixup only to the ESB2 (for now). We can apply it to other chips later if the same problem is found.

* [PATCH] pdc202xx_new: fix PLL/timing issuesSergei Shtylyov2006-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the CRC errors in the higher UltraDMA modes with the Promise PDC20268 and newer chips that always occur on non-x86 machines and when there are more than 2 adapters on x86 machines. Fix the overclocking issue for PDC20269 and newer chips that occurs when an UltraDMA/133 capable drive is connected. Here's the summary of changes: - add code to detect the PLL input clock detection and setup it output clock, remove the PowerMac hacks; - replace the macros accessing the indexed regiters with functions, switch to using them where appropriate, gather the PIO/MWDMA/UDMA timings into tables; - rewrite the speedproc() handler to set the drive's transfer mode first, and then override the timing registers set by hardware on UltraDMA/133 chips; - use better criterion for determining higher UltraDMA modes, and add comment concerning the doubtful value of the code enabling IORDY/prefetch; - replace the stupid 'pdcnew_new_' prefixes with mere 'pdcnew_'; - get rid of unneded spaces, parens and type casts, clean up some printk's, add some new lines here and there... This work is loosely based on these former patches by Albert Lee: [1] http://marc.theaimsgroup.com/?l=linux-ide&m=110992442032300 [2] http://marc.theaimsgroup.com/?l=linux-ide&m=110992457729382 [3] http://marc.theaimsgroup.com/?l=linux-ide&m=110992474205555 [4] http://marc.theaimsgroup.com/?l=linux-ide&m=111019224802939 Some PLL clock detection code was backported from his pata_pdc2027x driver... This code has been successfully tested by me on PDC2026[89] chips. I tried to keep this rework as several patches but it made no sense: [2] was largely a modification of the non-working timing override code, [3] by itself extended the overclocking issue to the case of non-UltraDMA/133 drives, and finally, the cleanup patch based on [1] ended up rejected...

| * [PATCH] drivers/ide/pci/generic.c: re-add the __setup("all-generic-ide",...)Adrian Bunk2006-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The change from __setup() to module_param_named() requires users to prefix the option with "generic.". This patch re-adds the __setup() additionally to the module_param_named(). Usually it would make sense getting rid of such an obsolete __setup() at some time, but considering that drivers/ide/ is slowly approaching a RIP status it's already implicitely scheduled for removal. This patch fixes kernel Bugzilla #7353.

| * [PATCH] ioc4: Enable build on non-SN2Brent Casavant2006-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SGI PCI-RT card, based on the SGI IOC4 chip, will be made available on Altix XE (x86_64) platforms in the near future. As such it is now a misnomer for the IOC4 base device driver to live under drivers/sn, and would complicate builds for non-SN2. This patch moves the IOC4 base driver code from drivers/sn to drivers/misc, and updates the associated Makefiles and Kconfig files to allow building on non-SN2 configs. Due to the resulting change in link order, it is now necessary to use late_initcall() for IOC4 subdriver initialization.

* 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.
