+ help
+ This option enables the Linux bootsplash screen.
+
+ The bootsplash is a full-screen logo or animation indicating a
+ booting system. It replaces the classic scrolling text with a
+ graphical alternative, similar to other systems.
+
+ Since this is technically implemented as a hook on top of fbcon,
+ it can only work if the FRAMEBUFFER_CONSOLE is enabled and a
+ framebuffer driver is active. Thus, to get a text-free boot,
+ the system needs to boot with vesafb, efifb, or similar.
+
+ Once built into the kernel, the bootsplash needs to be enabled
+ with bootsplash.enabled=1 and a splash file needs to be supplied.
+
+ Further documentation can be found in:
+ Documentation/fb/bootsplash.txt
+
+ If unsure, say N.
+ This is typically used by distributors and system integrators.

+====================
+The Linux bootsplash
+====================
+
+:Date: November, 2017
+:Author: Max Staudt <mstaudt@suse.de>
+
+
+The Linux bootsplash is a graphical replacement for the '``quiet``' boot
+option, typically showing a logo and a spinner animation as the system starts.
+
+Currently, it is a part of the Framebuffer Console support, and can be found
+as ``CONFIG_BOOTSPLASH`` in the kernel configuration. This means that as long
+as it is enabled, it hijacks fbcon's output and draws a splash screen instead.
+
+Purely compiling in the bootsplash will not render it functional - to actually
+render a splash, you will also need a splash theme file. See the example
+utility and script in ``tools/bootsplash`` for a live demo.
+
+
+
+Motivation
+==========
+
+- The '``quiet``' boot option only suppresses most messages during boot, but
+ errors are still shown.
+
+- A user space implementation can only show a logo once user space has been
+ initialized far enough to allow this. A kernel splash can display a splash
+ immediately as soon as fbcon can be displayed.
+
+- Implementing a splash screen in user space (e.g. Plymouth) is problematic
+ due to resource conflicts.
+
+ For example, if Plymouth is keeping ``/dev/fb0`` (provided via vesafb/efifb)
+ open, then most DRM drivers can't replace it because the address space is
+ still busy - thus leading to a VRAM reservation error.
+
+ See: https://bugzilla.opensuse.org/show_bug.cgi?id=980750
+
+
+
+Command line arguments
+======================
+
+``bootsplash.bootfile``
+ Which file in the initramfs to load.
+
+ The splash theme is loaded via request_firmware(), thus to load
+ ``/lib/firmware/bootsplash/mytheme`` pass the command line:
+
+ ``bootsplash.bootfile=bootsplash/mytheme``
+
+ Note: The splash file *has to be* in the initramfs, as it needs to be
+ available when the splash is initialized early on.
+
+ Default: none, i.e. a non-functional splash, falling back to showing text.
+
+
+
+sysfs run-time configuration
+============================
+
+``/sys/devices/platform/bootsplash.0/enabled``
+ Enable/disable the bootsplash.
+ The system boots with this set to 1, but will not show a splash unless
+ a splash theme file is also loaded.
+
+
+
+Kconfig
+=======
+
+``BOOTSPLASH``
+ Whether to compile in bootsplash support
+ (depends on fbcon compiled in, i.e. ``FRAMEBUFFER_CONSOLE=y``)
+
+
+
+Bootsplash file format
+======================
+
+A file specified in the kernel configuration as ``CONFIG_BOOTSPLASH_FILE``
+or specified on the command line as ``bootsplash.bootfile`` will be loaded
+and displayed as soon as fbcon is initialized.
+
+
+Main blocks
+-----------
+
+There are 3 main blocks in each file:
+
+ - one File header
+ - n Picture headers
+ - m (Blob header + payload) blocks
+
+
+Structures
+----------
+
+The on-disk structures are defined in
+``drivers/video/fbdev/core/bootsplash_file.h`` and represent these blocks:
+
+ - ``struct splash_file_header``
+
+ Represents the file header, with splash-wide information including:
+
+ - The magic string "``Linux bootsplash``" on big-endian platforms
+ (the reverse on little endian)
+ - The file format version (for incompatible updates, hopefully never)
+ - The background color
+ - Number of picture and blob blocks
+ - Animation speed (we only allow one delay for all animations)
+
+ The file header is followed by the first picture header.
+
+
+ - ``struct splash_picture_header``
+
+ Represents an object (picture) drawn on screen, including its immutable
+ properties:
+ - Width, height
+ - Positioning relative to screen corners or in the center
+ - Animation, if any
+ - Animation type
+ - Number of blobs
+
+ The picture header is followed by another picture header, up until n
+ picture headers (as defined in the file header) have been read. Then,
+ the (blob header, payload) pairs follow.
+
+
+ - ``struct splash_blob_header``
+ (followed by payload)
+
+ Represents one raw data stream. So far, only picture data is defined.
+
+ The blob header is followed by a payload, then padding to n*16 bytes,
+ then (if further blobs are defined in the file header) a further blob
+ header.
+
+
+Alignment
+---------
+
+The bootsplash file is designed to be loaded into memory as-is.
+
+All structures are a multiple of 16 bytes long, all elements therein are
+aligned to multiples of their length, and the payloads are always padded
+up to multiples of 16 bytes. This is to allow aligned accesses in all
+cases while still simply mapping the structures over an in-memory copy of
+the bootsplash file.
+
+
+Further information
+-------------------
+
+Please see ``drivers/video/fbdev/core/bootsplash_file.h`` for further
+details and possible values in the file.
+
+
+
+Hooks - how the bootsplash is integrated
+========================================
+
+``drivers/video/fbdev/core/fbcon.c``
+ ``fbcon_init()`` calls ``bootsplash_init()``, which loads the default
+ bootsplash file or the one specified on the kernel command line.
+
+ ``fbcon_switch()`` draws the bootsplash when it's active, and is also
+ one of the callers of ``set_blitting_type()``.
+
+ ``set_blitting_type()`` calls ``fbcon_set_dummyops()`` when the
+ bootsplash is active, overriding the text rendering functions.
+
+ ``fbcon_cursor()`` will call ``bootsplash_disable()`` when an oops is
+ being printed in order to make a kernel panic visible.
+
+``drivers/video/fbdev/core/dummyblit.c``
+ This contains the dummy text rendering functions used to suppress text
+ output while the bootsplash is shown.
+
+``drivers/tty/vt/keyboard.c``
+ ``kbd_keycode()`` can call ``bootsplash_disable()`` when the user
+ presses ESC or F1-F12 (changing VT). This is to provide a built-in way
+ of disabling the splash manually at any time.
+
+
+
+FAQ: Frequently Asked Questions
+===============================
+
+I want to see the log! How do I show the log?
+---------------------------------------------
+
+Press ESC while the splash is shown, or remove the ``bootsplash.bootfile``
+parameter from the kernel cmdline. Without that parameter, the bootsplash
+will boot disabled.
+
+
+Why use FB instead of modern DRM/KMS?
+-------------------------------------
+
+This is a semantic problem:
+ - What memory to draw the splash to?
+ - And what mode will the screen be set to?
+
+Using the fbdev emulation solves these issues.
+
+Let's start from a bare KMS system, without fbcon, and without fbdev
+emulation. In this case, as long as userspace doesn't open the KMS
+device, the state of the screen is undefined. No framebuffer is
+allocated in video RAM, and no particular mode is set.
+
+In this case, we'd have to allocate a framebuffer to show the splash,
+and set our mode ourselves. This either wastes a screenful of video RAM
+if the splash is to co-exist with the userspace program's own allocated
+framebuffer, or there is a flicker as we deactivate and delete the
+bootsplash's framebuffer and hand control over to userspace. Since we
+may set a different mode than userspace, we'd also have flicker due
+to mode switching.
+
+This logic is already contained in every KMS driver that performs fbdev
+emulation. So we might as well use that. And the correct API to do so is
+fbdev. Plus, we get compatibility with old, pure fbdev drivers for free.
+With the fbdev emulation, there is *always* a well-defined framebuffer
+to draw on. And the selection of mode has already been done by the
+graphics driver, so we don't need to reinvent that wheel, either.
+Finally, if userspace decides to use /dev/fbX, we don't have to worry
+about wasting video RAM, either.
+
+
+Why is the bootsplash integrated in fbcon?
+------------------------------------------
+
+Right now, the bootsplash is drawn from within fbcon, as this allows us
+to easily know *when* to draw - i.e. when we're safe from fbcon and
+userspace drawing all over our beautiful splash logo.
+
+Separating them is not easy - see the to-do list below.

+It may be helpful to differentiate between the system and the user
+switching off the bootsplash. Thus, the system may make it disappear and
+reappear e.g. for a password prompt, yet once the user has pressed ESC,
+it could stay gone.
+
+
+Fix buggy DRM/KMS drivers
+-------------------------
+
+Currently, the splash code manually checks for fbdev emulation provided by
+the ast, cirrus, and mgag200 DRM/KMS drivers.
+These drivers use a manual mechanism similar to deferred I/O for their FB
+emulation, and thus need to be manually flushed onto the screen in the same
+way.
+
+This may be improved upon in several ways:
+
+1. Changing these drivers to expose the fbdev BO's memory directly, like
+ bochsdrmfb does.
+2. Creating a new fb_ops->fb_flush() API to allow the kernel to flush the
+ framebuffer once the bootsplash has been drawn into it.
+
+
+Separating from fbcon
+---------------------
+
+Separating these two components would yield independence from fbcon being
+compiled into the kernel, and thus lowering code size in embedded
+applications.
+
+To do this cleanly will involve a clean separation of users of an FB device
+within the kernel, i.e. fbcon, bootsplash, and userspace. Right now, the
+legacy fbcon code and VT code co-operate to switch between fbcon and
+userspace (by setting the VT into KD_GRAPHICS mode). Installing a muxer
+between these components ensues refactoring of old code and checking for
+correct locking.

From: Anthony G. Basile <blueness@gentoo.org>
This patch adds support for a restricted user-controlled namespace on
tmpfs filesystem used to house PaX flags. The namespace must be of the
form user.pax.* and its value cannot exceed a size of 8 bytes.
This is needed even on all Gentoo systems so that XATTR_PAX flags
are preserved for users who might build packages using portage on
a tmpfs system with a non-hardened kernel and then switch to a
hardened kernel with XATTR_PAX enabled.
The namespace is added to any user with Extended Attribute support
enabled for tmpfs. Users who do not enable xattrs will not have
the XATTR_PAX flags preserved.

The encryption is only mandatory to be enforced when both sides are using
Secure Simple Pairing and this means the key size check makes only sense
in that case.
On legacy Bluetooth 2.0 and earlier devices like mice the encryption was
optional and thus causing an issue if the key size check is not bound to
using Secure Simple Pairing.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
FEATURES
This patch adds additional CPU options to the Linux kernel accessible under:
Processor type and features --->
Processor family --->
With the release of gcc 11.1 and clang 12.0, several generic 64-bit levels are
offered which are good for supported Intel or AMD CPUs:
• x86-64-v2
• x86-64-v3
• x86-64-v4
Users of glibc 2.33 and above can see which level is supported by current
hardware by running:
/lib/ld-linux-x86-64.so.2 --help | grep supported
Alternatively, compare the flags from /proc/cpuinfo to this list.[1]
CPU-specific microarchitectures include:
• AMD Improved K8-family
• AMD K10-family
• AMD Family 10h (Barcelona)
• AMD Family 14h (Bobcat)
• AMD Family 16h (Jaguar)
• AMD Family 15h (Bulldozer)
• AMD Family 15h (Piledriver)
• AMD Family 15h (Steamroller)
• AMD Family 15h (Excavator)
• AMD Family 17h (Zen)
• AMD Family 17h (Zen 2)
• AMD Family 19h (Zen 3)†
• Intel Silvermont low-power processors
• Intel Goldmont low-power processors (Apollo Lake and Denverton)
• Intel Goldmont Plus low-power processors (Gemini Lake)
• Intel 1st Gen Core i3/i5/i7 (Nehalem)
• Intel 1.5 Gen Core i3/i5/i7 (Westmere)
• Intel 2nd Gen Core i3/i5/i7 (Sandybridge)
• Intel 3rd Gen Core i3/i5/i7 (Ivybridge)
• Intel 4th Gen Core i3/i5/i7 (Haswell)
• Intel 5th Gen Core i3/i5/i7 (Broadwell)
• Intel 6th Gen Core i3/i5/i7 (Skylake)
• Intel 6th Gen Core i7/i9 (Skylake X)
• Intel 8th Gen Core i3/i5/i7 (Cannon Lake)
• Intel 10th Gen Core i7/i9 (Ice Lake)
• Intel Xeon (Cascade Lake)
• Intel Xeon (Cooper Lake)*
• Intel 3rd Gen 10nm++ i3/i5/i7/i9-family (Tiger Lake)*
• Intel 3rd Gen 10nm++ Xeon (Sapphire Rapids)‡
• Intel 11th Gen i3/i5/i7/i9-family (Rocket Lake)‡
• Intel 12th Gen i3/i5/i7/i9-family (Alder Lake)‡
Notes: If not otherwise noted, gcc >=9.1 is required for support.
*Requires gcc >=10.1 or clang >=10.0
†Required gcc >=10.3 or clang >=12.0
‡Required gcc >=11.1 or clang >=12.0
It also offers to compile passing the 'native' option which, "selects the CPU
to generate code for at compilation time by determining the processor type of
the compiling machine. Using -march=native enables all instruction subsets
supported by the local machine and will produce code optimized for the local
machine under the constraints of the selected instruction set."[2]
Users of Intel CPUs should select the 'Intel-Native' option and users of AMD
CPUs should select the 'AMD-Native' option.
MINOR NOTES RELATING TO INTEL ATOM PROCESSORS
This patch also changes -march=atom to -march=bonnell in accordance with the
gcc v4.9 changes. Upstream is using the deprecated -match=atom flags when I
believe it should use the newer -march=bonnell flag for atom processors.[3]
It is not recommended to compile on Atom-CPUs with the 'native' option.[4] The
recommendation is to use the 'atom' option instead.
BENEFITS
Small but real speed increases are measurable using a make endpoint comparing
a generic kernel to one built with one of the respective microarchs.
See the following experimental evidence supporting this statement:
