* firmware: use memory_read_from_buffer()Akinobu Mita2008-07-251-9/+3

* firmware: allow firmware files to be built into kernel imageDavid Woodhouse2008-07-101-2/+31
| | | | | | | | | | | | | | | Some drivers have their own hacks to bypass the kernel's firmware loader and build their firmware into the kernel; this renders those unnecessary. Other drivers don't use the firmware loader at all, because they always want the firmware to be available. This allows them to start using the firmware loader. A third set of drivers already use the firmware loader, but can't be used without help from userspace, which sometimes requires an initrd. This allows them to work in a static kernel.

* firmware: make fw->data constDavid Woodhouse2008-07-101-1/+1
| | | | | | | | | In preparation for supporting firmware files linked into the static kernel, make fw->data const to ensure that users aren't modifying it (so that we can pass a pointer to the original in-kernel copy, rather than having to copy it).

* firmware loader: printk when requesting firmwareCiaran McCreesh2008-04-291-0/+2
| | | | | | | | | | | Before requesting firmware, printk a message saying what we're requesting. This makes it easier to see what's going on, and provides an explanation for the huge silent delay that one would otherwise get after accidentally building ipw2200 as a non-module.

* Driver core: Revert "Fix Firmware class name collision"Michael E Brown2008-02-071-1/+2
| | | | | | | | | | | | | | | This reverts commit 109f0e93b6b728f03c1eb4af02bc25d71b646c59. The original patch breaks BIOS updates on all Dell machines. The path to the firmware file for the dell_rbu driver changes, which breaks all of the userspace tools which rely on it. Note that this patch re-introduces a problem with i2c name collision that was previously fixed by this patch.

* Driver core: change add_uevent_var to use a structKay Sievers2007-10-121-8/+3
| | | | | | | | | | | | | | | | | | This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

* sysfs: add parameter "struct bin_attribute *" in .read/.write methods for ↵Zhang Rui2007-07-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysfs binary attributes Well, first of all, I don't want to change so many files either. What I do: Adding a new parameter "struct bin_attribute *" in the .read/.write methods for the sysfs binary attributes. In fact, only the four lines change in fs/sysfs/bin.c and include/linux/sysfs.h do the real work. But I have to update all the files that use binary attributes to make them compatible with the new .read and .write methods. I'm not sure if I missed any. :( Why I do this: For a sysfs attribute, we can get a pointer pointing to the struct attribute in the .show/.store method, while we can't do this for the binary attributes. I don't know why this is different, but this does make it not so handy to use the binary attributes as the regular ones. So I think this patch is reasonable. :) Who benefits from it: The patch that exposes ACPI tables in sysfs requires such an improvement. All the table binary attributes share the same .read method. Parameter "struct bin_attribute *" is used to get the table signature and instance number which are used to distinguish different ACPI table binary attributes. Without this parameter, we need to offer different .read methods for different ACPI table binary attributes. This is impossible as there are various ACPI tables on different platforms, and we don't know what they are until they are loaded.

* sysfs: kill unnecessary attribute->ownerTejun Heo2007-07-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

* [PATCH] x86 microcode: using request_firmware to pull microcodeShaohua Li2006-09-271-1/+1
| | | | | | | | | | | | | | | | | | | Using request_firmware to pull ucode from userspace, so we don't need the application 'microcode_ctl' to assist. We name each ucode file according to CPU's info as intel-ucode/family-model-stepping. In this way we could split ucode file as small one. This has a lot of advantages such as selectively update and validate microcode for specific models, better manage microcode file, easily write tools for administerators and so on. with the changes, we should put all intel-ucode/xx-xx-xx microcode files into the firmware dir (I had a tool to split previous big data file into small one and later we will release new style data file).

* [PATCH] firmware: fix BUG: in fw_realloc_bufferJeff Moyer2006-03-201-2/+4
| | | | | | | | | | | | | | | The fw_realloc_buffer routine does not handle an increase in buffer size of more than 4k. It's not clear to me why it expects that it will only get an extra 4k of data. The attached patch modifies fw_realloc_buffer to vmalloc as much memory as is requested, instead of what we previously had + 4k. I've tested this on my laptop, which would crash occaisionally on boot without the patch. With the patch, it hasn't crashed, but I can't be certain that this code path is exercised.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
