Raw Normal View History

Linux-2.6.12-rc2 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!

menu "Generic Driver Options"
Driver core: add CONFIG_UEVENT_HELPER_PATH The kernel creates a process for every event that is send, even when there is no binary it could execute. We are needlessly creating around 200-300 failing processes during early bootup, until we have the chance to disable it from userspace. This change allows us to disable /sbin/hotplug entirely, if you want to, by setting UEVENT_HELPER_PATH="" in the kernel config.

help
Select this option if you don't have magic firmware for drivers that
need it.
If unsure, say Y.
config PREVENT_FIRMWARE_BUILD
bool "Prevent firmware from being built"
default y
help
Say yes to avoid building firmware. Firmware is usually shipped
with the driver, and only when updating the firmware a rebuild
should be made.
If unsure say Y here.

tristate "Userspace firmware loading support"
[PATCH] don't select CONFIG_HOTPLUG It's useful to be able to turn off CONFIG_HOTPLUG for compile-coverage testing and for section-checking coverage. But a few things go and select CONFIG_HOTPLUG, making it a royal PITA to turn the thing off. It's only turnable offable if CONFIG_EMBEDDED anyway. So let's make those things depend on HOTPLUG, not select it.

firmware: Add CONFIG_EXTRA_FIRMWARE option This allows arbitrary firmware files to be included in the static kernel where the firmware loader can find them without requiring userspace to be alive.

config EXTRA_FIRMWARE
string "External firmware blobs to build into the kernel binary"
depends on FW_LOADER
help
This option allows firmware to be built into the kernel, for the
cases where the user either cannot or doesn't want to provide it from
userspace at runtime (for example, when the firmware in question is
required for accessing the boot device, and the user doesn't want to
use an initrd).
This option is a string, and takes the (space-separated) names of the
firmware files -- the same names which appear in MODULE_FIRMWARE()
and request_firmware() in the source. These files should exist under
the directory specified by the EXTRA_FIRMWARE_DIR option, which is
by default the firmware/ subdirectory of the kernel source tree.
So, for example, you might set CONFIG_EXTRA_FIRMWARE="usb8388.bin",
copy the usb8388.bin file into the firmware/ directory, and build the
kernel. Then any request_firmware("usb8388.bin") will be
satisfied internally without needing to call out to userspace.
WARNING: If you include additional firmware files into your binary
kernel image which are not available under the terms of the GPL,
then it may be a violation of the GPL to distribute the resulting
image -- since it combines both GPL and non-GPL work. You should
consult a lawyer of your own before distributing such an image.
config EXTRA_FIRMWARE_DIR
string "Firmware blobs root directory"
depends on EXTRA_FIRMWARE != ""
default "firmware"
help
This option controls the directory in which the kernel build system
looks for the firmware files listed in the EXTRA_FIRMWARE option.
The default is the firmware/ directory in the kernel source tree,
but by changing this option you can point it elsewhere, such as
the /lib/firmware/ directory or another separate directory
containing firmware files.

devres: device resource management Implement device resource management, in short, devres. A device driver can allocate arbirary size of devres data which is associated with a release function. On driver detach, release function is invoked on the devres data, then, devres data is freed. devreses are typed by associated release functions. Some devreses are better represented by single instance of the type while others need multiple instances sharing the same release function. Both usages are supported. devreses can be grouped using devres group such that a device driver can easily release acquired resources halfway through initialization or selectively release resources (e.g. resources for port 1 out of 4 ports). This patch adds devres core including documentation and the following managed interfaces. * alloc/free : devm_kzalloc(), devm_kzfree() * IO region : devm_request_region(), devm_release_region() * IRQ : devm_request_irq(), devm_free_irq() * DMA : dmam_alloc_coherent(), dmam_free_coherent(), dmam_declare_coherent_memory(), dmam_pool_create(), dmam_pool_destroy() * PCI : pcim_enable_device(), pcim_pin_device(), pci_is_managed() * iomap : devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(), devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(), pcim_iomap(), pcim_iounmap() Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

[PATCH] Driver Core: Add /sys/hypervisor when needed To have a home for all hypervisors, this patch creates /sys/hypervisor.
