* kbuild: make $(checker-shell ) strip spaces around the resultLinus Torvalds2007-02-081-3/+2Star
| | | | | | | | | | | | It looks like GNU make version 3.80 (but apparently not 3.81) adds leading whitespace to the result of the checker-shell execution. This strips them off explicitly. Also, don't bother symlinking the output file to /dev/null. It's likely as expensive as just writing the temp-file, and we need to remove it anyway afterwards.

| * ACPI support for IDE devicesHannes Reinecke2007-02-076-0/+770
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The arch hooks arch_setup_msi_irq and arch_teardown_msi_irq are now responsible for allocating and freeing the linux irq in addition to setting up the the linux irq to work with the interrupt. arch_setup_msi_irq now takes a pci_device and a msi_desc and returns an irq. With this change in place this code should be useable by all platforms except those that won't let the OS touch the hardware like ppc RTAS. Signed-off-by: Eric W.

| * | msi: Kill the msi_desc array.Eric W. Biederman2007-02-084-24/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to be able to get from an irq number to a struct msi_desc. The msi_desc array in msi.c had several short comings the big one was that it could not be used outside of msi.c. Using irq_data in struct irq_desc almost worked except on some architectures irq_data needs to be used for something else. So this patch adds a msi_desc pointer to irq_desc, adds the appropriate wrappers and changes all of the msi code to use them. The dynamic_irq_init/cleanup code was tweaked to ensure the new field is left in a well defined state. Signed-off-by: Eric W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since msi_remove_pci_irq_vectors is designed to be called during hotplug remove it is actively wrong to query the hardware and expect meaningful results back. To that end remove the pci_find_capability calls. Testing dev->msi_enabled and dev->msix_enabled gives us all of the information we need. Signed-off-by: Eric W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the removal of msi_lookup_irq all of the functions using msi_lock operated on a single device and none of them could reasonably be called on that device at the same time. Since what little synchronization that needs to happen needs to happen outside of the msi functions, msi_lock could never be contended and as such is useless and just complicates the code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function msi_lookup_irq was horrible. As a side effect of running it changed dev->irq, and then the callers would need to change it back. In addition it does a global scan through all of the irqs, which seems to be the sole justification of the msi_lock. To remove the neede for msi_lookup_irq I added first_msi_irq to struct pci_dev. Then depending on the context I replaced msi_lookup_irq with dev->first_msi_irq, dev->msi_enabled, or dev->msix_enabled. msi_enabled and msix_enabled were already present in pci_dev for other reasons.

| * | MSI: Combine pci_(save|restore)_msi/msix_stateMichael Ellerman2007-02-083-11/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PCI save/restore code doesn't need to care about MSI vs MSI-X, all it really wants is to say "save/restore all MSI(-X) info for this device". This is borne out in the code, we call the MSI and MSI-X save routines side by side, and similarly with the restore routines. So combine the MSI/MSI-X routines into pci_save_msi_state() and pci_restore_msi_state(). It is up to those routines to decide what state needs to be saved.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I don't see any reason why we need pci_msi_quirk, quirk code can just call pci_no_msi() instead. Remove the check of pci_msi_quirk in msi_init(). This is safe as all calls to msi_init() are protected by calls to pci_msi_supported(), which checks pci_msi_enable, which is disabled by pci_no_msi(). The pci_disable_msi routines didn't check pci_msi_quirk, only pci_msi_enable, but as far as I can see that was a bug not a feature.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's an existing quirk for the kernel to use 1k IO space granularity on the Intel P64H2. It turns out however that pci_setup_bridge() in drivers/pci/setup-bus.c reads in the IO base and limit address register masks it off to the nearest 4k, and writes it back. This causes the kernel to be on 1k boundaries and the hardware to be 4k aligned. The patch below fixes the problem.
