From ac17b8b57013a3e38d1958f66a218f15659e5752 Mon Sep 17 00:00:00 2001 From: Dave Kleikamp Date: Mon, 3 Oct 2005 15:32:11 -0500 Subject: [PATCH 001/243] JFS: make special inodes play nicely with page balancing This patch fixes up a few problems with jfs's reserved inodes. 1. There is no need for the jfs code setting the I_DIRTY bits in i_state. I am ashamed that the code ever did this, and surprised it hasn't been noticed until now. 2. Make sure special inodes are on an inode hash list. If the inodes are unhashed, __mark_inode_dirty will fail to put the inode on the superblock's dirty list, and the data will not be flushed under memory pressure. 3. Force writing journal data to disk when metapage_writepage is unable to write a metadata page due to pending journal I/O.

Signed-off-by: Richard Hirst Do a proper depth-first search returning parents before children, using the new klist infrastructure. Signed-off-by: Richard Hirst Fixed parisc_device traversal so that pdc_stable works again Fixed check_dev so it doesn't dereference a parisc_device until it has verified the bus type Signed-off-by: Randolph Chung Convert pa_dev->hpa from an unsigned long to a struct resource. Use insert_resource() instead of request_mem_region(). Request resources at bus walk time instead of driver probe time. Don't release the resources as we don't have any hotplug parisc_device support yet. Add parisc_pathname() to conveniently get the textual representation of the hwpath used in sysfs. Inline the remnants of claim_device() into its caller. Signed-off-by: Matthew Wilcox I noticed that some of the STI regions weren't showing up in iomem. Reading the STI spec indicated that all STI devices occupy at least 32MB. So check for STI HPAs and give them 32MB instead of 4kB.

Thanks to Joel Soete for pointing out this oversight. Signed-off-by: Grant Grundler 2.6.14-rc2-pa3 move "sync" outside the main loop that fills IO Pdir. Signed-off-by: Grant Grundler remove explicit use of sr0 in fdc ops. Thanks to Joel Soete for reminding me were I added those... Signed-off-by: Grant Grundler 2.6.14-rc2-pa2 - make SBA more anal about invalidating pdir entries Previous code cleared the valid flag a pdir entry but it did NOT guarantee this change was visible to the PDIR before writing the PCOM register. Ie the SBA could pick up a stale entry if the write happened to hit the SBA before the cacheline was flushed from the cache. Long term, I think I want to make this a compile time flag. Developement tree should enable anal pdir checking by default and Debian can disable it with either a CONFIG option or one-line patch. fdc/sync options can only negatively affect performance though I haven't measure how much yet. If someone can run netperf TCP_RR across gige and compare -pa1 and -pa2, that would be sufficient. Cleaned up the use of "fdc" to make sure it's using "kernel" space id (specify sr0 but maps to sr4-7). It seems a bit fragile to assume "sr1" gets loaded with KERNEL_SPACE which is how the code works today. Tested on 32 and 64-bit SMP kernels on j6k. Signed-off-by: Grant Grundler remove PDC_NARROW from SBA and document history of PDC_NARROW a bit. It will still show up in an older kernel's .config file. Signed-off-by: Grant Grundler if/ifdef cleanups from Joel Soete. Signed-off-by: Grant Grundler 2.6.12-rc4-pa2 fix 32-bit support for Astro platforms o Since my last SBA code change, SBA could allocate more than 1GB of IOVA space on Astro boxes with more than 1GB of RAM when running 32-bit kernel. This is bad since IOMMU can only talk to the first 1GB at most. Kudos to jejb for quickly spotting that bug. o jejb also noted SBA should *always* reject DMA masks > 32-bits since DMA-mapping.txt indicates caller should try again with 32-bits. o off-by-one error when comparing the mask to IOVA space size.

Signed-off-by: Grant Grundler Take into account nullified insn and lock functions for profiling This is needed at the end of functions; it is typical that the return branch nullifies the next insn, which is in the next function. This causes profiling data to show up against the "wrong" function. We also count lock times against the locker. This is consistent with other architectures.

Gives about 25% perf improvement with a rsync test with ext3. Signed-off-by: Randolph Chung fix ext3 performance - ext2_find_next_zero() was culprit. Kudos to jejb for pointing out the the possibility that ext2_test_bit and ext2_find_next_zero() may in fact not be enumerating bits in the bitmap because of endianess. Took sparc64 implementation and adapted it to our tree. I suspect the real problem is ffz() wants an unsigned long and was getting garbage in the top half of the unsigned int. Not confirmed but that's what I suspect.

I think header files that might go to user space should use something userspace will know about (__LP64__).

Main advantage is it allows use of msleep() in the led_LCD_driver to "atomically" perform two MMIO writes (CMD, then DATA). Lead to nice cleanup of the main led_work_func() and led_LCD_driver().

The problem has been around since 2.6.9-rc2-pa6 when we allowed floating point registers to be used in kernel code. The essence of the problem is that gcc prefers to use floating point for integer divides and multiples. Further, it can rely on the values in the no clobber fp regs being correct across a function call. Unfortunately, our task switch function only saves the integer no clobber registers, not the fp ones, so if gcc makes a function call to any function in the kernel which could sleep, the values it is relying on in any no clobber floating point register may be lost. In the case of alloc_slabmgmt, the value of the page offset is being stored in %fr12 across a call to kmem_getpages(), which sleeps if no pages are available. Thus, the offset can be trashed and the slab code can end up with a completely bogus address leading to corruption. Kudos to Randolph who came up with the program to trip this problem at will and thus allowed it to be tracked and fixed.

While there are no platforms in the tree ATM that use it, it has been tested tested on the IXP2350 NPU and I would like to get the support for that chipset upstream one piece at a time. There are also other Intel chipset ports in development that are waiting on this to go upstream. The patch replaces the print formats for physical addresses with %016llx which will create a bit extraneous output on 32-bit systems, but I think that is cleaner than having #ifdefs, specially since users will only see the output in error cases.

I submitted an ALSA patch for this http://thread.gmane.org/gmane.linux.alsa.devel/27804 issue and it was suggested that it might be preferable to change the register definitions to use u32. Most other subarches seem to use u32 for their register type, at least the ones which use a __REG macro (like the PXA) do. Nico indicated in the thread above that he wouldn't mind this patch. Changing the type required fixes for opposite warnings in the pxa2xx usb gadget code but that was the only new warning introduced on defconfig or lubbock, mainstone and our own PXA255 boards.

Honor power mode parameter of pxa_cpu_suspend(mode), no longer force to 3 (sleep). Full Deep Sleep low-power mode support for PXA27x is pending generic PM interfaces to select more than 2 suspend-to-RAM-style power modes, but this is expected soon. This can be hardcoded in the meantime by replacing the pxa_cpu_suspend() parameter value. From David Burrage and Todd Poynor. Try #2 removes one of the register copies and moves the code to save the pxa_cpu_suspend parameter to immediately surround the call that requires the parameter value be preserved.

This will allow us to (hopefully) fix up the input and video class subsystem mess. But please people, don't go crazy and start making huge trees of class devices, you should only need 2 levels deep to get everything to work (remember to use a class_interface to get notification of a new class device being added to the system.) Oh, this also allows us to have the possibility of potentially, someday, moving /sys/block into /sys/class. The main hindrance is that pesky /dev numberspace issue...

The main culprits are due to the initialisation functions not being declared in a header file. Also, the firmware.c file should include to get the prototype of firmware_register() and firmware_unregister(). This patch moves the init function declerations from the init.c file to the base.h, and ensures it is included in all the relevant c sources. It also adds to the included headers for firmware.c. The patch does not solve all the sparse errors generated, but reduces the count significantly. drivers/base/core.c:161:1: warning: symbol 'devices_subsys' was not declared.

Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

Breaking the suspend transition into several -stages affords the platform flexibility in performing device power -management based on the requirements of the system and the -user-defined policy. - -SUSPEND_NOTIFY notifies the device that a suspend transition is about -to happen. This happens on system power state transitions to verify -that all devices can successfully suspend. - -A driver may choose to fail on this call, which should cause the -entire suspend transition to fail. A driver should fail only if it -knows that the device will not be able to be resumed properly when the -system wakes up again. It could also fail if it somehow determines it -is in the middle of an operation too important to stop. - -SUSPEND_DISABLE tells the device to stop I/O transactions. When it -stops transactions, or what it should do with unfinished transactions -is a policy of the driver. After this call, the driver should not -accept any other I/O requests. - -SUSPEND_SAVE_STATE tells the device to save the context of the -hardware. This includes any bus-specific hardware state and -device-specific hardware state. A pointer to this saved state can be -stored in the device's saved_state field. - -SUSPEND_POWER_DOWN tells the driver to place the device in the low -power state requested. - -Whether suspend is called with a given level is a policy of the -platform. Some levels may be omitted; drivers must not assume the -reception of any level. However, all levels must be called in the -order above; i.e. notification will always come before disabling; -disabling the device will come before suspending the device. - -All calls are made with interrupts enabled, except for the -SUSPEND_POWER_DOWN level. +suspend is called to put the device in a low power state. int (*resume) (struct device * dev, u32 level); -Resume is used to bring a device back from a low power state. Like the -suspend transition, it happens in several stages. - -RESUME_POWER_ON tells the driver to set the power state to the state -before the suspend call (The device could have already been in a low -power state before the suspend call to put in a lower power state). - -RESUME_RESTORE_STATE tells the driver to restore the state saved by -the SUSPEND_SAVE_STATE suspend call. - -RESUME_ENABLE tells the driver to start accepting I/O transactions -again. Depending on driver policy, the device may already have pending -I/O requests. - -RESUME_POWER_ON is called with interrupts disabled. The other resume -levels are called with interrupts enabled. - -As with the various suspend stages, the driver must not assume that -any other resume calls have been or will be made. Each call should be -self-contained and not dependent on any external state. +Resume is used to bring a device back from a low power state.

This patch incorporate the review comments by Jeff Garzik. 2. Renamed USO as UFO (UDP Fragmentation Offload) 3. udp sendfile support with UFO This patches uses scatter-gather feature of skb to generate large UDP datagram. Below is a "how-to" on changes required in network device driver to use the UFO interface. UDP Fragmentation Offload (UFO) Interface: ------------------------------------------- UFO is a feature wherein the Linux kernel network stack will offload the IP fragmentation functionality of large UDP datagram to hardware. This will reduce the overhead of stack in fragmenting the large UDP datagram to MTU sized packets 1) Drivers indicate their capability of UFO using dev->features |= NETIF_F_UFO | NETIF_F_HW_CSUM | NETIF_F_SG NETIF_F_HW_CSUM is required for UFO over ipv6. 2) UFO packet will be submitted for transmission using driver xmit routine. UFO packet will have a non-zero value for "skb_shinfo(skb)->ufo_size" skb_shinfo(skb)->ufo_size will indicate the length of data part in each IP fragment going out of the adapter after IP fragmentation by hardware. skb->data will contain MAC/IP/UDP header and skb_shinfo(skb)->frags[] contains the data payload. The skb->ip_summed will be set to CHECKSUM_HW indicating that hardware has to do checksum calculation. Hardware should compute the UDP checksum of complete datagram and also ip header checksum of each fragmented IP packet. For IPV6 the UFO provides the fragment identification-id in skb_shinfo(skb)->ip6_frag_id. The adapter should use this ID for generating IPv6 fragments.

While some other sensors chips respond to all addresses in 0x290-0x297 range, Winbond chips respond to 0x295-0x296 only (this behavior is implied by documentation, and matches behavior observed on real systems). This is not problem alone, as no BIOS was found to put something at these unused addresses, and sensors chip itself provides nothing there as well. But in addition to only respond to these two addresses, also BIOS vendors report in their ACPI-PnP structures that there is some resource at I/O address 0x295 of length 2. And when later this hwmon driver attempts to request region with base 0x290/length 8, it fails as one request_region cannot span more than one device. Due to this we have to ask only for region this hardware really occupies, otherwise driver cannot be loaded on systems with ACPI-PnP enabled.

Also, the original driver would crash on module load on the Alpha because the PCI memory region was not remapped into kernel memory.

The original implementation was known to have bugs (credits go to Hideki Iwamoto for reporting many of them recently), and was incomplete due to a conceptual limitation. The rewrite affects only software PEC. Hardware PEC needs very little code and is mostly untouched. Technically, both implementations differ in that the original one was emulating PEC in software by modifying the contents of an i2c_smbus_data union (changing the transaction to a different type), while the new one works one level lower, on i2c_msg structures (working on message contents). Due to the definition of the i2c_smbus_data union, not all SMBus transactions could be handled (at least not without changing the definition of this union, which would break user-space compatibility), and those which could had to be implemented individually. At the opposite, adding PEC to an i2c_msg structure can be done on any SMBus transaction with common code. Advantages of the new implementation: * It's about twice as small (from ~136 lines before to ~70 now, only counting i2c-core, including blank and comment lines). The memory used by i2c-core is down by ~640 bytes (~3.5%). * Easier to validate, less tricky code. The code being common to all transactions by design, the risk that a bug can stay uncovered is lower. * All SMBus transactions have PEC support in I2C emulation mode (providing the non-PEC transaction is also implemented). Transactions which have no emulation code right now will get PEC support for free when they finally get implemented. * Allows for code simplifications in header files and bus drivers (patch follows). Drawbacks (I guess there had to be at least one): * PEC emulation for non-PEC capable non-I2C SMBus masters was dropped. It was based on SMBus tricks and doesn't quite fit in the new design. I don't think it's really a problem, as the benefit was certainly not worth the additional complexity, but it's only fair that I at least mention it. Lastly, let's note that the new implementation does slightly affect compatibility (both in kernel and user-space), but doesn't actually break it. Some defines will be dropped, but the code can always be changed in a way that will work with both the old and the new implementations. It shouldn't be a problem as there doesn't seem to be many users of SMBus PEC to date anyway.

At least, this demonstrates that the new PEC support logic in i2c-core can properly deal with chips with partial PEC support.
