* kernel: default ARM_PMU on for armsr/armv8Mathew McBride2023-08-191-0/+1
| | | | | | | | | CONFIG_ARM_PMU (Arm Performance Monitor Unit) is a requirement to use KVM (virtualization) from Linux 5.11+, as the virtualised guest has virtualized PMU access. Signed-off-by: Mathew McBride <matt@traverse.com.au> (cherry picked from commit 76d4a7c84a97a5555b1962ddb9fc694b7e1f6ba8)

| | | | | | | | armvirt target has been renamed to armsr (Arm SystemReady), so the config defaults need to be changed as well. Signed-off-by: Mathew McBride <matt@traverse.com.au> (cherry picked from commit 40ce6a7920a8f56d07228795a526576a8762aead)

* build: use 128MiB as the boot/kernel partition size on armvirt targetMathew McBride2023-06-131-0/+1
| | | | | | | | | | | | | | | | | The nominal partition type for EFI boot partitions is FAT32, which has a minimum size of 32MiB on a 512-byte-sector block device. To ensure that the boot partition is created as FAT32 set a size well above this minimum. A useful discussion about EFI partition sizes can be found here: https://superuser.com/questions/1310927/what-is-the-absolute-minimum-size-a-uefi-system-partition-can-be I have found 128MiB works pretty consistently across both tools (mkfs.fat) and firmwares (EDKII) Signed-off-by: Mathew McBride <matt@traverse.com.au> (cherry picked from commit 71e56b2ff1e8aeb3205784c0b5f8ca6ba0fbbf63)
* grub2: enable EFI for armvirtMathew McBride2023-06-131-4/+5
| | | | | | | | | | | | This adds a separate package for EFI on Arm SystemReady compatible machines. 32-bit Arm UEFI is supported as well. It is very similar to x86-64 EFI setup, without the need for BIOS backward compatibility and slightly different default modules.

* kernel: Set CONFIG_FRAME_WARN depending on targetHauke Mehrtens2023-06-021-0/+11

| | | | | | | This reverts commit c07038da27cefa5a93e433909b9aca594386ddc1. MODULE_ALLOW_BTF_MISMATCH is not available in Linux 5.15. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
* kernel: add MODULE_ALLOW_BTF_MISMATCH optionTianling Shen2023-05-181-0/+10
| | | | | | | | | | | BTF mismatch can occur for a separately-built module even when the ABI is otherwise compatible and nothing else would prevent successfully loading. Add a new config to control how mismatches are handled. By default, preserve the current behavior of refusing to load the module. If MODULE_ALLOW_BTF_MISMATCH is enabled, load the module but ignore its BTF information. Signed-off-by: Tianling Shen <cnsztl@immortalwrt.org>
* treewide: cleanup kernel symbol referencesNick Hainke2023-05-121-1/+0
| | | | | | | | | | | | | | | We only use 5.15 kernel. So remove all those unnecessary symbols referencing 5.10 or 5.15 kernel. Can be found with: git grep -E 'LINUX_5_1(0|5)' Note that we remove the dependency from "sound-soc-chipdip-dac" instead of removing the complete kernel package. The 5.15 version bump forgot to delete the "@LINUX_5_10" dependency. The kernel package is still needed in 5.15 kernel. Signed-off-by: Nick Hainke <vincent@systemli.org>
* kernel: improve handling of CONFIG_IO_URINGTony Ambardar2023-05-031-1/+2
| | | | | | | | | | | | | | | | | | | | | | Kernel setting CONFIG_IO_URING supports high-performance I/O for file access and servers, generally for more performant platforms, and adds ~45 KB to kernel sizes. The need for this on less "beefy" devices is questionable, as is the size cost considering many platforms have kernel size limits which require tricky repartitioning if outgrown. The size cost is also large relative to the ~180 KB bump expected between major OpenWRT kernel releases. No OpenWrt packages have hard dependencies on this; samba4 and mariadb can take advantage if available (+KERNEL_IO_URING:liburing) but otherwise build and work fine. Since CONFIG_IO_URING is already managed via the KERNEL_IO_URING setting in Config-kernel.in (default Y), remove it from those target configs which unconditionally enable it, and update the defaults to enable it conditionally only on more powerful 64-bit x86 and arm devices. It may still be manually enabled as needed for high-performance custom builds. Signed-off-by: Tony Ambardar <itugrok@yahoo.com>

* kernel: set default values for ARM low level debugging symbolsRobert Marko2023-02-081-0/+6
| | | | | | | | | | | | | | | | | | | | | Set default values for KERNEL_DEBUG_LL and KERNEL_DEBUG_LL_UART_NONE again as both of these symbols are non visible if KERNEL_EARLY_PRINTK is not selected and KConfig wont write their value to .config. This usually is the intended behaviour, but in OpenWrt we are relying on the KConfig to set these and disable the debug console settings that multiple targets like mvebu have set in their kernel config. This was the behaviour before removing all of the "default n" settings as KConfig by default considers symbols disabled but they are not visible anymore and thus their value is not set in .config and build system then later does not override the values from target kernel config. So, to restore the behaviour to the previous one lets a default value for KERNEL_DEBUG_LL and KERNEL_DEBUG_LL_UART_NONE.

* scripts/download.pl: make the download tool configurableChristian Marangi2022-10-201-0/+14
| | | | | | | | | | | | | | | | | | | | | | Introduce a new option in the "Advanced configuration options" to configure a custom download tool. By declaring a string in "Use custom download tool" an user can force what command to use to download package. With the string empty the default tool used is curl, with wget as a fallback if not available. download.pl supports 3 tools officially aria2c, curl and wget. If one of the tool is used in this config, download.pl will use the default args to make use of them. If the provided string is different than aria2c, curl or wget, the command is used as is and the download url will be appended at the end of such command. While at it also tweak the tool selection logic and chose the tool only once when the script is called and move aria2c specific variables in the relevant section.

* bcm53xx: use -falign-functions=32 for kernel compilationRafał Miłecki2022-07-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Northstar SoCs have pretty small CPU caches and their performance is heavily affected by cache hits & misses. It means that all kind of random code changes can affect performance as they often reorganize (change alignment & possibly reorder) kernel symbols. It was discussed in ARM / net mailinglists: 1. ARM router NAT performance affected by random/unrelated commits [1] [2] 2. Optimizing kernel compilation / alignments for network performance [3] [4] It seems that -falign-functions can be used as a partial workaround. It doesn't solve all cases (e.g. documented watchdog one [5]) but it surely helps with many of them. A complete long term solution may be PGO (profile-guided optimization) but it isn't available at this point.
