* platform-v7a: kernel: lzo is a lot faster at boottimeMichael Olbrich2017-10-121-2/+2
| | | | | | | | On vexpress, this lowers the 2nd pass boot time from 38 s to 31 s. Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de> [add benchmark numbers to commit message] Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
* platform-v7a: kernel: reboot on panicRobert Schwebel2017-10-111-1/+1
| | | | | | | Change the kernel config to reboot on panic. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de> Reviewed-by: Rouven Czerwinski <r.czerwinski@pengutronix.de>
* platform-v7a: kernel: switch on CONFIG_PREEMPTRobert Schwebel2017-10-111-9/+8
| | | | | | | | "reason" suggests that the typical embedded use-cases are more sensitive to latency than throughput, so a fully preemptible kernel is preferred. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de> Reviewed-by: Rouven Czerwinski <r.czerwinski@pengutronix.de>
* platform-v7a: kernel: enable lockup detector, as suggested by reasonRobert Schwebel2017-10-111-3/+6
| | | | | | | | | | "Reason" suggests that the kernel lockup detector should be active, as it's low overhead and potentially provides useful debug output when the system is failing due to a lockup. This patch does the necessary changes for the kernel configuration. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de> Reviewed-by: Rouven Czerwinski <r.czerwinski@pengutronix.de>
* kernel: version bump 4.12.0 -> 4.13.0Robert Schwebel2017-09-301-37/+50
| | | | Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
* platform-v7a: kernel: randomize freelist order used on creating new pagesRobert Schwebel2017-07-211-1/+1
| | | | | | | | As suggested by "reason", activate the kernel feature to randomize the freelist order used on creating new pages. This results in a reduction of the predictability of addresses against heap overflows. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
* platform-v7a: kernel: activate strong stack protectorRobert Schwebel2017-07-211-3/+3
| | | | | | | As suggested by "reason", activate the stack protection feature. The only negative impact should be a small increase in kernel size. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
* platform-v7a: kernel: activate hardened user copyRobert Schwebel2017-07-211-1/+2
| | | | | | | As suggested by "reason", activate the kernel option to protect against obviously wrong memory regions when copying memory to/from the kernel. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
* platform-v7a: kernel: restrict dmesg access to rootRobert Schwebel2017-07-211-1/+1
| | | | | | As suggested by "reason", restrict access to the dmesg output to root. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
* platform-v7a: kernel: deactivate quota supportRobert Schwebel2017-07-211-8/+2
| | | | | | | As suggested by "reason", disable quota support, as we don't need it on embedded systems. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
* kernel: enable thermal driver for i.MX6Robert Schwebel2017-07-121-1/+34
| | | | | | This change was suggested by reason-ptxdist. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
* kernel: avoid bufferbloadRobert Schwebel2017-07-121-1/+51
| | | | | | | | | | reason-ptxdist suggests: "fq_codel helps fight the network bufferbloat problem. It is believed to be a good default with no tuning required for most workloads. Downstream distributions may override this choice. On 10Gbit servers that do not do forwarding, "fq" may perform better. Systems without a good clocksource should use "pfifo_fast". (from systemd NEWS)" Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
* kernel: enable hang check detectorRobert Schwebel2017-07-121-2/+7
| | | | | | | | reason-ptxdist suggests: "The kernel lockup detector should be active, as it's low overhead and potentially provides useful debug output when the system is failing due to a lockup." Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
* kernel: enable hardware crypto driver on MX6Robert Schwebel2017-07-121-6/+40
| | | | | | | As suggested by reason-ptxdist: "The CAAM driver should be enabled on MX6 to provide entropy to the kernel." Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
* platform-v7a: kernel: avoid ext2 warning on startupRobert Schwebel2017-07-041-5/+3
| | | | | | | | | Deactivate support for ext2 + ext3, as our rootfs is ext4. Add a hint to the kernel command line, in order to avoid this warning: EXT4-fs (mmcblk0p1): couldn't mount as ext2 due to feature incompatibilities Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>

* platform-v7a: add i.MX6 support to kernelconfigSascha Hauer2017-06-301-9/+108
| | | | | | | | | As i.MX6 is an ARM v7a as well, add support for it to the v7a kernel configuration. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> [improve commit message] Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
