There are many changes in this file and its impossible to cover this with a patch for now current and all kernels back
We are using same hack in UWE drivers.
This is just a cosmetic change. Patches have been consolidated
into one patch within each corresponding linux version directory.
Added: linux-6.6 (RC-1)
Removed: linux-6.2/6.3

Also added some cleanup fixes to silence some of the compiler warnings,
fixes for issues during inserting and removing xradio module and fixes
for possible data corruption on vmmaped stack.
All of these fixes were taken from https://github.com/fifteenhex/xradio
* patch: misc: rtw88: wireless-next: 2023-08-25
Updated: 6.1 / 6.4
Added: 6.5
For doc sake, this update makes 6.1 slightly differrent than 6.4 and
6.5 in one particular area of main.c.
As shown here:
7746e2fa87
6.1 requires we use del_timer_sync, where the above releases use
timer_delete_sync.
Tested-on: ODROID-C4 X96-AIR BPI-CM4 (linux 6.x.y)

> tl-dr:
> - maximize OCI cache hit ratio across nightlies/releases/PRs/etc;
> - publish simple `Version:`'s that don't include a crazy hash in repo and images
> - introduce `output/packages-hashed` directory
> - radically change the `output/debs` directory structure
- simplify artifact's `prepare_version()` method for `deb` and `deb-tar` artifacts:
- `artifact_base_dir` and `artifact_final_file` will now be auto-calculated; thus removed from each artifact (except `rootfs`)
- `artifact_deb_repo` ("global", "jammy", "bookworm") is now required; "global" means common across all RELEASES
- `artifact_deb_arch` is now required, "all" is arch-independent, otherwise use `${ARCH}`
- `artifact_map_debs` is now auto-calculated based on the above, and shouldn't be specified manually
- `artifact_final_version_reversioned` is optional, and can force the final version of the artifact (specific for the `base-files` case)
- artifacts that need special handling for reversioning can add function names to `artifact_debs_reversion_functions` array (`base-files` and `bsp-cli` cases)
- artifacts `prepare_version()` should set `artifact_version`, but _never_ include it in other variables; `artifact_version` is now changed by framework after `prepare_version()` returns
- no longer use/refer/mention `${REVISION}` when building packages. All packages should be `${REVISION}`-agnostic.
- `${REVISION}` (actually, `artifact_final_version_reversioned`) will be automatically swapped in the `control` file during reversioning
- `fakeroot_dpkg_deb_build()` now takes exactly two arguments: the directory to pack, and the deb ID (key of `artifact_map_packages` dict); add this change in all the artifact's code for this
- `obtain_complete_artifact()`:
- automatically adds `-Rxxxx` "revisioning-hash" to `artifact_version`, by hashing the revisioning functions and any `artifact_debs_reversion_functions` set
- calculates more complex subdirectory paths for both the `output/packages-hashed` and `output/debs`/`output/debs-beta` directories
- with the new subdirectories we can be sure a re-version is already done correctly and can skip it (eg, for partial `download-debs` re-runs)
- in the future we can automatically clean/remove old versions that are no longer relevant based on the dir structure
- exports a lot more information to JSON, including the new subdirectory paths
- comment-out code that implemented `skip_unpack_if_found_in_caches`, I'm very unsure why we had this in the first place
- `obtain_artifact_from_remote_cache()`
- for `deb` type artifacts, OCI won't preserve the subdirectory structure, so move downloaded files to the correct subdirectory manually
- this is not needed for `deb-tar`, since that can preserve the dir structure itself
- introduce `artifacts-reversion.sh` and its main function `artifact_reversion_for_deployment()`
- this has the logic for reversioning .deb's, by `ar`-unpacking them, changing `control.tar` (and possibly `data.tar`), handling `.xz` compression, etc.
- also handles hashing those functions, for consistency. Any changes in reversioning code actually change the artifact itself so we're not caught by surprise
- by default, it changes `control` file only:
- replace `Version:` (which is the hash-version originally) with `artifact_final_version_reversioned` (which is mostly just `${REVISION}`)
- add a custom field `Armbian-Original-Hash:` with the original hash-version
- `artifact_reversion_for_deployment()` is called by
- new CLI wrapper `cli_obtain_complete_artifact()`, used for CLI building of specific artifact, but also for `download-artifact`
- `build_artifact_for_image()` used during image build
- `armbian-bsp-cli-deb.sh`: move `${REVISION}` related stuff from the main package build to new reversioning functions.
- `artifact-armbian-base-files.sh`: move `${REVISION}` related stuff from the main package build to new reversioning functions.
- `kernel`:
- add some custom fields to `DEBIAN/control`:
- `Armbian-Kernel-Version:` / `Armbian-Kernel-Version-Family:` (for future use: cleanup of usage of `Source: ` field which should be removed)
- declutter the `Description:` field, moving long description out of the first line
- obtain `IMAGE_INSTALLED_KERNEL_VERSION` from the reversioned deb (this is still a hack and has not been fixed)
- `uboot`:
- declutter the `Description:` field, moving long description out of the first line
- use the reversioned .deb when deploying u-boot to the image
- `main_default_build_packages()` now stores reversioned values and complete paths to reversioned .deb's
- `list_installed_packages()` now compares custom field `Armbian-Original-Hash: `, and not the `Version:` to make sure debs in the image are the ones we want
- `install_artifact_deb_chroot()` is a new wrapper around `install_deb_chroot()` for easy handling of reversioned debs
- use it everywhere `install_deb_chroot()` was used in `distro-agnostic.sh` and `distro-specific.sh`
- change deployment dir to not include REVISION or ARCH
- get rid uboot's CHOSEN_UBOOT, REVISION and ARCH in the directory name.
- no two u-boot debs can be installed in the same machine anyway
- this should avoid (late) patching errors that might happen during a point release bump like `6.4.5` -> `6.4.6` cos we'd be using the wrong cached drivers patch
- using the SHA1 will instead (possibly) trigger the "real patching failure", during drivers-harness when building a new driver patch cache
- also try to cleanup old caches in the old format so we've not many leftovers -- each patch is ~150mb
- `USE_TMPFS=no` disables usage of generic tmpfs mechanism (still possibly used for rootfs/image building, which is unrelated), for last-resort cases
- use better/more descriptive `temp_dir_id`'s for kernel build than `k` (now `kernel_dest_install_dir`) and `kd` (now `kernel_debs_temp_dir`)
- specific image/dtb/headers packaging already had decent names, same for other .deb's
- replace `mktemp -d` with `mktemp -d --tmpdir "${temp_dir_id}-XXXXX"` in `prepare_temp_dir_in_workdir_and_schedule_cleanup()`, so we know what's using what in tmpfs
With this change, setting EXTRAWIFI=no will disable all wireless
patches applied within drivers_network.sh script. Also since #5265
the rtl88x2cs patches were suppose to be not applied to 6.1+ kernel
onwards, instead they were disabled entirely. As this was done by
adding EXTRAWIFI=no, its now replaced with kernel version limit.
Keeping EXTRAWIFI=no there would have made those patches to apply
which would have changed the meaning of the flag.
Cope with the fix in stable 6.3.13 bf353116d1bf and 6.5-rc1 e8c2af660ba0
"wifi: cfg80211: fix regulatory disconnect with OCB/NAN".
That is the removal of REGULATORY_IGNORE_STALE_KICKOFF
from the wireless regulator internal API to fix any driver
that allowed OCB/NAN.
Note this code will need to be expanded once and if 6.4 include the
above fixup.

Use multiple consecutive reads in rtw_sdio_read_port() to limit the number of bytes which are copied by the host from the card in one MMC/SDIO transfer. This allows receiving a buffer that's larger than the hosts max_req_size (number of bytes which can be transferred in one MMC/SDIO transfer). As a result of this the skb_over_panic error is gone as the rtw88 driver is now able to receive more than 1536 bytes from the card (either because the incoming packet is larger than that or because multiple packets have been aggregated).

- introduced at 228354ed69
- simply creating the dir solves it
- reported to author, let's hope for an -rc2 fix.
- better logging when DEBUG=yes (don't pass "-s"(ilent) to make clean)
This brings the patch set up to 2023-06-22 wireless-next
Drivers tested;
8822CS. 8821CU and 8723DS
Notables;
Not seeing random dmesg spam `rtw_8822cs failed to get tx report from firmware` which I would see on both the CS and CU from time to time.

Patch set includes a complete backport of RTW88 as it currently stands, along with extras
Extra:
Patch: RTL8723DS (SDIO)
Patch: _rtw_download_firmware() warn: missing unwind goto?
Hack: SDIO RX Aggregation Limiting
I only have two units available to me with an 8822CS module and in my testing this is only required on the BPI-CM4IO. With out LIMITING the unit will either kernel panic or not be able to send or receive.
This is currently being looked into:
https://lore.kernel.org/linux-wireless/CAFBinCBaXtebixKbjkWKW_WXc5k=NdGNaGUjVE8NCPNxOhsb2g@mail.gmail.com/T/#u
It may be possible to just set LIMITING across all builds, but that to me seems like a poor choice. This requires testing.

# Brief detour. Turns out that HardKernel's vendor odroidxu4 kernel already has this driver
# "slipstreamed" into it, complete with a bunch of PDF files and other junk.
# See https://github.com/hardkernel/linux/tree/odroid-5.4.y/drivers/net/wireless/rtl8812au
# If we remove them here, the resulting patch will contain binary diffs which are unsupported by patch(1).
# So if building for the odroidxu4/current, we'll leave the original files in place, and just overwrite
# the possibly-updated source files (not PDFs and such). Thanks, HardKernel.

- even Rich'er patch output by colorizing certain strings green/yellow/red
- BASE_GIT_TAG now very sneakily also accepts a branch name
- IMPORTANT: this includes: BREAKING CHANGE: patches failing to apply now break the build. fixes#4958
- also break on legacy `process_patch_file()` failure, remove `EXIT_PATCHING_ERROR`
- `odroidxu4`'s firmware hook for vendor kernel. such is life, no use warning.
- `sun50iw9`: vendor kernel with extension, proven working, stop warning
- old kernels don't have working headers, it's a fact of life, remove warning
- partially revert 6ef394d95d (thus bring back the TUI/dialog for selecting KERNEL_CONFIGURE=yes/no)
- partially revert d890b418c7 (thus bring back the capacity to config & build image in one go)
- stop after configuring kernel, but only if command is `kernel-config`, not regular image-build KERNEL_CONFIGURE=yes
- all interactive commands now **don't build the artifact** anymore; just patches/.configs are produced and then build ends
- user is required to put the produced patches in the right place and build again, for full consistency
- split ATF and U-BOOT manual patching process; use CLI command `atf-patch` to patch ATF, and `uboot-patch` to patch u-boot
- non-interactive artifact builds are now 100% sans-stdin
- introduce `uboot-config` CLI command; still experimental, only produces a defconfig and not a patch
- reworked `userpatch_create()` to be (hopefully) more useful:
- detects a previous patch and offers to apply it before continuing
- enters a loop showing the diff, and only proceeds when user indicates he's happy with the patch
- produces `mbox`-formatted patches via `format-patch` and standard Armbian parameters
- uses MAINTAINER and MAINTAINERMAIL instead of git configuration (so it works in containers)
- don't allow image builds with any patching or configuring _at all_ (it has been deprecated with a warning for months already, and results are inconsistent)
- determinining if `/boot` is vfat is more complex than it looks;
- use a common function to unify across all scripts
- during image build, the kernel install is always done with a non-fat, non-mounted /boot
- use a special variable passed through the env so unified function can know ahead of time
- introduce `extra_apt_envs` param to `chroot_sdcard_apt_get()`; array with extra environment vars
- if vfat /boot:
- `linux-update-symlinks` is not called (Debian would just choke on this)
- don't even try to symlink Armbian stuff, move instead
- more/better logging board-side (unfortunately mixed in all the set -x debugs)
- bsp-cli: does not require aggregation
- bsp-desktop / desktop: requires aggregation
- 'desktop' packaged moved out of 'bsp' folder, it is NOT a bsp
- make consistent naming/folders
- extract .sh generation workflow into 'declare -f' magic functions
- `SHOW_DEBIAN=yes` to bump most of `DEBIAN/xxx` stuff to screen
- artifact armbian-bsp-desktop: use aggregation, require certain vars, CLI forces `BUILD_DESKTOP=yes`; requires BOARD
- artifact armbian-desktop: use aggregation, require certain vars, CLI forces `BUILD_DESKTOP=yes`, not require `BOARD` anymore
- cli: commands: fix artifact aliases, reorder
- desktop/bsp-desktop: add `config_dump` method; fix `artifact_map_debs` ref subdir and name
- artifact bsps: require aggregation to build, not to list what needs to be built
- distro-agnostic: fix install of `armbian-bsp-cli` (not `armbian-bsp`)
- armbian-bsp-cli: add `_config_dump` method, use configuration with aggregation, add required vars check
- distro-specific: fix installation of `fake-ubuntu-advantage-tools`

- split some functions, to better control the interactive piece in the _middle_ of kernel config process
- no more `kernel_config_maybe_interactive()`, now `kernel_config()` that controls its own logging sections
