From 5658374766d9e0249bd04e9d62bdb8456b916b64 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Fri, 21 Oct 2005 22:33:38 -0400 Subject: [PARISC] Convert parisc_device tree to use struct device klists Fix parse_tree_node. much more needs to be done to fix this file. Signed-off-by: Matthew Wilcox Make drivers.c compile based on a patch from Pat Mochel. From: Patrick Mochel Signed-off-by: Kyle McMartin Fix drivers.c to create new device tree nodes when no match is found. 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.

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().

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.

The ide-scsi + st (+serverworks ide controller) combo results in a hard lockup of the machine which I have not had the energy to debug, so I turned to ide-tape (which seems to work). The system in question debian stable, using udev to manage /dev. The following patch to ide-tape.c allows udev to create the cdev nodes for my drive.

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.

That way we'll catch all unsupported commands, not only I2C_SMBUS_PROC_CALL. * Refactor some code. * Convert some dev_dbg into dev_err. Errors better be reported even in non-debug mode. * Do not verify that the final reset succeeded. It'll be checked at the beginning of the next transaction anyway. * Use the driver name to reserve the I/O region. * Do not print the contents of the SMBREV register, it reads 0 on all chips I've seen so far. * Some other minor fixes all over the place.

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.

I2C_SMBUS_I2C_BLOCK_MAX has always been defined to the same value as I2C_SMBUS_BLOCK_MAX, and this will never change: setting it to a lower value would make no sense, setting it to a higher value would break i2c_smbus_data compatibility. There is no point in changing i2c_smbus_data to support larger block transactions in SMBus mode, as no SMBus hardware supports more than 32 byte blocks.

The key change is that it uses the new __iomem/iowrite8/ioread8 functions to abstract the direct or memory-mapped variants of register access. Also, the original driver would crash on module load on the Alpha because the PCI memory region was not remapped into kernel memory. I have managed the following testing: * compiled and tested it on my Alpha UP2000+ system. * compiles cleanly for x86 but I don't have the hardware to test.

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.

Only the ADM1032 chip supports it, and in a rather tricky way, which is why this patch comes with documentation reinforcements. At least, this demonstrates that the new PEC support logic in i2c-core can properly deal with chips with partial PEC support. As enabling PEC causes a significant performance drop, it can be disabled through a sysfs file (unsurprisingly named "pec").
