2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau4-4/+0
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2007-02-12[PATCH] mark struct file_operations const 3Arjan van de Ven2-2/+2
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2007-02-07ACPI support for IDE devicesHannes Reinecke5-0/+743
This patch implements ACPI integration for generic IDE devices. The ACPI spec mandates that some methods are called during suspend and resume. And consequently there most modern Laptops cannot resume properly without it. According to the spec, we should call '_GTM' (Get Timing) upon suspend to store the current IDE adapter settings. Upon resume we should call '_STM' (Set Timing) to initialize the adapter with the stored settings; afterwards '_GTF' (Get Taskfile) should be called which returns a buffer with some IDE initialisation commands. Those commands should be passed to the drive. There are two module params which control the behaviour of this patch: 'ide=noacpi' Do not call any ACPI methods (Disables any ACPI method calls) 'ide=acpigtf' Enable execution of _GTF methods upon resume. Has no effect if 'ide=noacpi' is set. 'ide=acpionboot' Enable execution of ACPI methods during boot. This might be required on some machines if 'ide=acpigtf' is selected as some machines modify the _GTF information depending on the drive identification passed down with _STM.

This is for the Delking/Lexar/ASKA/etc.. 32-bit cardbus IDE CompactFlash adapter card. It's probably way out of sync with the latest driver model (??), but it still builds/works. I'm not interested in doing much of a rewrite, other than for libata someday, as I no longer use the card myself. But lots of other people do seem to use it, so it might be nice to see it "in-tree".

2007-02-07ide: add Toshiba TC86C001 IDE driver (take 2)Sergei Shtylyov3-0/+314
This is the driver for the Toshiba TC86C001 GOKU-S PCI IDE controller, completely reworked from the original brain-damaged Toshiba's 2.4 version. This single channel UltraDMA/66 controller is very simple in programming, yet Toshiba managed to plant many interesting bugs in it. The particularly nasty "limitation 5" (as they call the errata) caused me to abuse the IDE core in a possibly most interesting way so far. However, this is still better than the #ifdef mess in drivers/ide/ide-io.c that the original version included (well, it had much more mess)...

2007-02-07piix: fix 82371MX enablebitsSergei Shtylyov1-2/+8
According to the datasheet, Intel 82371MX (MPIIX) actually has only a single IDE channel mapped to the primary or secondary ports depending on the value of the bit 14 of the IDETIM register at PCI config. offset 0x6C (the register at 0x6F which the driver refers to. doesn't exist). So, disguise the controller as dual channel and set enablebits masks/values such that only either primary or secondary channel is detected enabled. Also, preclude the IDE probing code from reading PCI BARs, this controller just doesn't have them (it's not the separate PCI function like the other PCI controllers), it only decodes the legacy addresses.

2007-02-07hpt366: HPT36x PCI clock detection fixSergei Shtylyov1-2/+6
Fix minor coding mistake in the HPT36x PCI clock detection code noticed by Bartlomiej Zolnierkiewicz -- it always reported 33 MHz due to the missing 'break' statements. This, however, most probably never mattered -- in fact, I was thinking of removing the 25/40 MHz cases completely since HPT36x BIOSes didn't seem to set any other value than 7 into the 'cmd_high_time' field, i.e. supported only 33 MHz PCI. Note that in the original driver there was another bug: 25 and 40 MHz cases were interchanged. Since the 'cmd_high_time' field is in units of PCI clocks, a lower clock count just *cannot* correspond to a higher frequency, i. e. it should be 5 for 25 MHz PCI and 9 for 40 MHz PCI, not the other way around.

2007-02-07hpt366: init code rewriteSergei Shtylyov1-362/+489
Finally, rework the driver init. code to correctly handle all the chip variants HighPoint has created so far. This should cure the rest of the timing issues in the driver (especially, on 66 MHz PCI) caused by the HighPoint's habit of switching the base DPLL clock with every new revision of the chips... - switch to using the enumeration type to differ between the numerous chip variants, matching PCI device/revision ID with the chip type early, at the init_setup stage; - extend the hpt_info structure to hold the DPLL and PCI clock frequencies, stop duplicating it for each channel by storing the pointer in the pci_dev structure: first, at the init_setup stage, point it to a static "template" with only the chip type and its specific base DPLL frequency, the highest supported DMA mode, and the chip settings table pointer filled, then, at the init_chipset stage, allocate per-chip instance and fill it with the rest of the necessary information; - get rid of the constant thresholds in the HPT37x PCI clock detection code, switch to calculating PCI clock frequency based on the chip's base DPLL frequency; - switch to using the DPLL clock and enable UltraATA/133 mode by default on anything newer than HPT370/A; - fold PCI clock detection and DPLL setup code into init_chipset_hpt366(), unify the HPT36x/37x setup code and the speedproc handlers by joining the register setting lists into the table indexed by the clock selected; - add enablebits for all the chips to avoid touching disabled channels (though the HighPoint BIOS seem to only disable the primary one on HPT371/N); - separate the UltraDMA and MWDMA masks there to avoid changing PIO timings when setting an UltraDMA mode in hpt37x_tune_chipset(). This version has been tested on HPT370/302/371N. Thanks to Alan for the inspiration. Hopefully, his libata driver will also benefit from the work done on this "obsolete" driver...

Clean up DMA timeout handling for HPT370: - hpt370_lostirq_timeout() cleared the DMA status which made __ide_dma_end() called afterwards return the incorrect result, and the DMA engine was reset both before and after stopping DMA while the HighPoint drivers only do it after (which seems logical) -- fix this and also rename the function; - get rid of the needless mutual recursion in hpt370_ide_dma_end() and hpt370_ide_dma_timeout(); - get rid of hpt370_lostirq_timeout() since hwif->ide_dma_end() called from the driver's interrupt handler later does all its work.

2007-01-05[PATCH] atiixp: Old drivers/ide layer driver for the ATIIXP hang fixAlan1-8/+10
When the old IDE layer calls into methods in the driver during error handling it is essentially random whether ide_lock is already held. This causes a deadlock in the atiixp driver which also uses ide_lock internally for locking. Switch to a private lock instead.

2007-01-05[PATCH] via82cxxx: fix cable detectionBartlomiej Zolnierkiewicz1-73/+65
This patch fixes 2.6.15 regression, is straightforward and tested. Cable detection got broken probably while converting the driver to support multiple controllers. Cable detection is done by examining how BIOS configured the attached devices. The current code is broken in that it examines the status *after* modifying Clk66 configuration ending up detecting 40c cables as 80c. This patch fixes it.

2006-12-30[PATCH] PIIX/SLC90E66: PIO mode fallback fixSergei Shtylyov2-28/+25
The fallback to PIO mode in the hwif->dma_check() handler doesn't work in the Intel PIIX and SMsC SLC90E66 IDE drivers because: - config_drive_for_dma() calls the hwif->speedproc() handler with a wrong mode number (unbiased by XFER_PIO_0) in case of the PIO fallback; - hwif->tuneproc() handler doesn't really set the drive's own speed (this is not fixed as yet).

2006-12-30[PATCH] PIIX: remove check for broken MW DMA mode 0Sergei Shtylyov1-31/+0
There's no need to check in piix_config_drive_for_dma() for broken MW DMA mode 0 as this mode is not supported by the driver (it sets hwif->mwdma_mask to 0x6), and hence can't be selected by ide_dma_speed(). (Alan sayeth "Probably right but if not you've got a subtle corruptor. Should at least stick a BUG_ON mode 0 setting right close when the mode is set.")

And then drop a few hunks which conflicted with outstanding work.

2006-12-13[PATCH] HPT37x: read f_CNT saved by BIOS from portSergei Shtylyov1-3/+3
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!

2006-12-13[PATCH] ide: fix HPT3xx hotswap supportSergei Shtylyov1-79/+36
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.

2006-12-13[PATCH] ide: optimize HPT37x timing tablesSergei Shtylyov1-230/+174
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.
