* brcm2708: add squashfs rootfs imageChristian Lamparter2018-05-181-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a image with squashfs as the root filesystem. A rootfs_data partition will be generated on the first boot and placed inside the rootfs partition (just after the squashfs image). advantages: - it is possible to migrate from an existing -ext4 installation and back via sysupgrade. - existing partition layout will not be lost. - slightly smaller image size. - support for attendedsysupgrade disadvantages: - needs f2fs + tools as well. This is because fs-tools decides on the blocksize of the sdcard. So either f2fs or ext4 can get choosen as the rootfs_data filesystem (depends on the size of the root partition). - rootfs_data is placed into the rootfs partition. This makes it difficult for tools that expect a /dev/mmc0pX device. It also makes it difficult for data recovery tools since they might not expect to find a embedded partition or will be confused. For people with existing build configurations: make sure to include mkf2fs and f2fsck package into the image... Otherwise the new -squashfs image will boot of a ram-overlay and won't keep the configurations after a reboot.

* target: disable CONFIG_PROC_PAGE_MONITOR on most targetsJo-Philipp Wich2018-01-131-1/+0
| | | | | | | | | | Disable CONFIG_PROC_PAGE_MONITOR in most places and only keep it enabled for virtual targets such as malta or potent ones like x86. This saves up to 4KB of uncompressed kernel size and significantly decreases CPU load under certain workloads. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
* kernel: move CONFIG_KASAN to generic configStijn Tintel2018-01-021-1/+0
| | | | | | | | | | While bumping 4.14, the kernel build failed due to missing CONFIG_KASAN symbol. Move it to generic config instead of defining it for all arm64 and x86/64 targets. It was only added in 4.0, so not needed in config-3.18. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
* kernel: cleanup CONFIG_SCHED_HRTICKStijn Tintel2017-06-291-1/+0
| | | | | | | Remove CONFIG_SCHED_HRTICK from target configs, as it was added to the generic config in b47fd7656336162360ebf66147326763ddae3f8d. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
* kernel: disable CONFIG_SG_POOL by defaultSergey Ryazanov2017-06-071-0/+1
| | | | | | | | CONFIG_SG_POOL symbol is selected only by CONFIG_SCSI, since the last one is disabled by default then disable CONFIG_SG_POOL by default too. And explicitly enable it only for platforms that use CONFIG_SCSI. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com>
* brcm2708: enable cpufreqStijn Tintel2017-05-231-4/+14
| | | | | | | | | | | | | With cpufreq disabled, the CPU stays locked at the frequency set by the bootloader. This severely degrades performance as the bootloader sets the CPU at the lowest frequency by default. Enable cpufreq for all subtargets and use the ondemand governor. Tested bcm2708 on RPi0W. Tested bcm2709 and bcm2710 on RPi3. Reported-by: Bryan Mayland <bmayland@capnbry.net> Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
* brcm2708: disable CONFIG_BCM2835_THERMAL by defaultRafał Miłecki2017-04-151-0/+1
| | | | | | | | | | | This fixes: Thermal sensors on bcm2835 SoC (BCM2835_THERMAL) [N/m/y/?] (NEW) aborted! This symbol depends on ARCH_BCM2835 so it should be OK to disable it at brcm2708 target only.

| | | | | | | 64 bit support for Raspberry Pi 3 is experimental. However, bcm2709 subtarget should serve as a stable and compatible 32 bit support. Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>
