* FS_ENET: OF-related fixup for FEC and SCC MAC'sVitaly Bordug2007-01-303-7/+14
| | | | | | | | | | | Updated direct resource pass with ioremap call, make it grant proper IRQ mapping, stuff incompatible with the new approach were respectively put under #ifndef CONFIG_PPC_MERGE. It is required so that both ppc and powerpc could utilize fs_enet effectively.

* b44: Fix frequent link changesMichael Chan2007-01-301-15/+20
| | | | | | | | | | | | | | | | | | | | | This fixes the issue of frequent link changes under heavy traffic reported below: http://bugzilla.kernel.org/show_bug.cgi?id=7696 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=216338 The b44 chip occasionally needs to be reset when ISTAT_ERRORS are encountered. The reset sequence includes a PHY reset that will take many seconds to complete and cause the link to go down and up. By skipping the PHY reset, it will greatly reduce the interruption when ISTAT_ERRORS are encountered. Change the full_reset parameter to reset_kind parameter in b44_init_hw(). This will allow PHY reset to be skipped when ISTAT_ERRORS are encountered.

For drivers/ide this was handled by the architecture's "pci_get_legacy_ide_irq()" function, but in libata we just hard-code the numbers 14 and 15. This patch provides asm-powerpc/libata-portmap.h which maps the IRQ as appropriate, having added a pci_dev argument to the ATA_{PRIM,SECOND}ARY_IRQ macros. There's probably a better way to do this -- especially if we observe that the _only_ case in which this seemingly-generic "pci_get_legacy_ide_irq()" function returns anything other than 14 and 15 for primary and secondary respectively is the case of the AMD8111 on the Maple board -- couldn't we handle that with a special case in the pata_amd driver, or perhaps with a PCI quirk for Maple to switch it into native mode during early boot and assign resources properly?

| * | ahci: use 0x80 as wait stat value instead of 0xffTejun Heo2007-01-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before hardreset, ahci initialized stat part of received FIS area to 0xff to wait for the first D2H Reg FIS which would change the value to device ready state. This used to work but now libata considers status value of 0xff as device not present making this wait prone to failure. This patch makes ahci use 0x80 for the wait stat value instead of 0xff to fix the above problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a GFP_KERNEL allocation is attempted in md while the mddev_lock is held, it is possible for a deadlock to eventuate. This happens if the array was marked 'clean', and the memalloc triggers a write-out to the md device. For the writeout to succeed, the array must be marked 'dirty', and that requires getting the mddev_lock. So, before attempting a GFP_KERNEL allocation while holding the lock, make sure the array is marked 'dirty' (unless it is currently read-only).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow noflush suspend/resume of device-mapper device only for the case where the device size is unchanged. Otherwise, dm-multipath devices can stall when resumed if noflush was used when suspending them, all paths have failed and queue_if_no_path is set. Explanation: 1. Something is doing fsync() on the block dev, holding inode->i_sem 2. The fsync write is blocked by all-paths-down and queue_if_no_path 3. Someone requests to suspend the dm device with noflush. Pending writes are left in queue. 4. In the middle of dm_resume(), __bind() tries to get inode->i_sem to do __set_size() and waits forever. 'noflush suspend' is a new device-mapper feature introduced in early 2.6.20. So I hope the fix being included before 2.6.20 is released. Example of reproducer: 1. Create a multipath device by dmsetup 2. Fail all paths during mkfs 3. Do dmsetup suspend --noflush and load new map with healthy paths 4.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In most cases we check the size of the bitmap file before reading data from it. However when reading the superblock, we always read the first PAGE_SIZE bytes, which might not always be appropriate. So limit that read to the size of the file if appropriate. Also, we get the count of available bytes wrong in one place, so that too can read past the end of the file.

After some cpufreq debugging i tracked the regression back to the following (totally correct) bug-fix commit: commit 0916bd3ebb7cefdd0f432e8491abe24f4b5a101e Author: Dave Jones <davej@redhat.com> Date: Wed Nov 22 20:42:01 2006 -0500 [PATCH] Correct bound checking from the value returned from _PPC method. This bugfix, which makes other laptops work, made a previously hidden (BIOS) bug visible on my laptop. The bug is the following: if the _PPC (Performance Present Capabilities) optional ACPI object is queried /after/ bootup then the BIOS reports an incorrect value of '2'. My laptop (Lenovo T60) has the following performance states supported: 0: 1833000 1: 1333000 2: 1000000 Per ACPI specification, a _PPC value of '0' means that all 3 performance states are usable. A _PPC value of '1' means states 1 .. 2 are usable, a value of '2' means only state '2' (slowest) is usable. now, the _PPC object is optional, and it also comes with notification. Furthermore, when a CPU object is initialized, the _PPC object is initialized as well. So the following evaluation of the _PPC object is superfluous: [<c028ba5f>] acpi_processor_get_platform_limit+0xa1/0xaf [<c028c040>] acpi_processor_register_performance+0x3b9/0x3ef [<c0111a85>] acpi_cpufreq_cpu_init+0xb7/0x596 [<c03dab74>] cpufreq_add_dev+0x160/0x4a8 [<c02bed90>] sysdev_driver_register+0x5a/0xa0 [<c03d9c4c>] cpufreq_register_driver+0xb4/0x176 [<c068ac08>] acpi_cpufreq_init+0xe5/0xeb [<c010056e>] init+0x14f/0x3dd And this is the point where my laptop's BIOS returns the incorrect value of '2'. Note that it has not sent any notification event, so the value is probably not really intentional (possibly spurious), and Windows likely doesnt query it after bootup either. Maybe the value is kept at '2' normally, and is only set to the real value when a true asynchronous event (such as AC plug event, battery switch, etc.) occurs. So i /think/ this is a grey area of the ACPI spec: per the letter of the spec the _PPC value only changes when notified, so there's no reason to query it after the system has booted up. So in my opinion the best (and most compatible) strategy would be to do the change below, and to not evaluate the _PPC object in the acpi_processor_get_performance_info() call, but only evaluate it if _PPC is present during CPU object init, or if it's notified during an asynchronous event. This change is more permissive than the previous logic, so it definitely shouldnt break any existing system. This also happens to fix my laptop, which is merrily chugging along at 1.83 GHz now. Yay!

This problem was not in 2.6.19. The backtrace (on MIPS) was: [<8024db6c>] kobject_uevent_env+0x54c/0x5e8 [<802a8264>] store_uevent+0x1c/0x3c (in drivers/class.c) [<801cb14c>] subsys_attr_store+0x2c/0x50 [<801cb80c>] flush_write_buffer+0x38/0x5c [<801cb900>] sysfs_write_file+0xd0/0x190 [<80181444>] vfs_write+0xc4/0x1a0 [<80181cdc>] sys_write+0x54/0xa0 [<8010dae4>] stack_done+0x20/0x3c flush_write_buffer() passes kobject of spi_master_class.subsys to subsys_addr_store(), then subsys_addr_store() passes a pointer to a struct subsystem to store_uevent() which expects a pointer to a struct class_device. The problem seems subsys_attr_store() called instead of class_device_attr_store(). This mismatch was caused by commit 3bd0f6943520e459659d10f3282285e43d3990f1, which overrides kset of master class. This made spi_master_class.subsys.kset.ktype NULL so subsys_sysfs_ops is used instead of class_dev_sysfs_ops. The commit was to fix spi_busnum_to_master(). Here is a patch fixes this function in other way, just searching children list of class_device.

* | [PATCH] KVM: MMU: Perform access checks in walk_addr()Avi Kivity2007-01-262-40/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Check pte permission bits in walk_addr(), instead of scattering the checks all over the code. This has the following benefits: 1. We no longer set the accessed bit for accessed which fail permission checks. 2. Setting the accessed bit is simplified. 3. Under some circumstances, we used to pretend a page fault was fixed when it would actually fail the access checks. This caused an unnecessary vmexit. 4. The error code for guest page faults is now correct. The fix helps netbsd further along booting, and allows kvm to pass the new mmu testsuite.

Some hang completely requiring physical power removal while others fail to wake up till the link is hardreset a couple of times. The addition of slumber on power down was never driven by real need. It just followed what ahci spec said literally. The spec itself seems faulty in that it doesn't consider devices (not controllers) which don't support link powersaving mode. Theory never matches reality when it comes to dark allys of cheap ATA/ATAPI world. It's just unrealistic to expect vendors to test rarely used link powersaving feature rigorously. This patch makes ahci more friendly to the coldness of reality. This shouldn't have any negative effect - when suspend operation succeeds, we power off the whole machine; otherwise, we wake up everything. I can't see any reason to be so elaborate with powering down the link in the first place. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* | | sata_nv: don't rely on NV_INT_DEV indication with ADMARobert Hancock2007-01-241-8/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several people reported issues with certain drive commands timing out on sata_nv controllers running in ADMA mode. The commands in question were non-DMA-mapped commands, usually FLUSH CACHE or FLUSH CACHE EXT. From experimentation it appears that the NV_INT_DEV indication isn't always set when a legitimate command completion interrupt is received on a legacy-mode command, at least not on these controllers in ADMA mode. When a command is pending on the port, force the flag on always in the irq_stat value before calling nv_host_intr so that the drive busy state is always checked by ata_host_intr. This also fixes some questionable code in nv_host_intr which called ata_check_status when a command was pending and ata_host_intr returned "unhandled". If the device interrupted at just the wrong time this could cause interrupts to be lost. Signed-off-by: Robert Hancock <hancockr@shaw.ca> Signed-off-by: Jeff Garzik <jeff@garzik.org>
