    [RT-AC86U] Accelerated crypto with /dev/crypto

    Dropbear could easily be complied for aarch64 because it only depends on the pre-compiled toolchain libraries. /tmp/home/root# ldd dropbear linux-vdso.so.1 (0x0000007fb2a20000) libutil.so.1 => /lib/aarch64/libutil.so.1 (0x0000007fb29e2000) libcrypt.so.1 =>...

    [RT-AC86U] Accelerated crypto with /dev/crypto

    Here's some results. The HND toolchain is 'soft float' only. # openssl speed -evp aes-256-cbc -elapsed You have chosen to measure elapsed time instead of user CPU time. Doing aes-256-cbc for 3s on 16 size blocks: 32781468 aes-256-cbc's in 3.01s Doing aes-256-cbc for 3s on 64 size blocks...

    [RT-AC86U] Accelerated crypto with /dev/crypto

    I agree and I think that /dev/crypto is the performance bottleneck. So I close with test results of an aarch64 version of openssl compiled with the Asuswrt toolchain. The "no-asm" option was removed. Not using /dev/crypto or bcmspu anymore. LD_LIBRARY_PATH=. ./openssl speed -evp...

    [RT-AC86U] Accelerated crypto with /dev/crypto

    Here's results for Cryptsetup 2.0.1 benchmark on the RT-AC86U. Cryptsetup uses AF_ALG which is a socket interface from userspace to kernelspace crypto. Linux kernel Cryptographic API (not accelerated) modprobe -r cryptodev modprobe -r bcmspu for M in...

    [RT-AC86U] Accelerated crypto with /dev/crypto

    I included the stats for BCM SPU in my results for the Cryptsetup benchmark. FYI, the following command crash my router. modprobe -r bcmspu cat /sys/kernel/debug/bcmspu/stats

    Entware-3x for new HND platform (GT-AC5300 and RT-AC86U) with asuswrt-merlin firmware

    Asuswrt-Merlin firmware can be patched to make a /dev/crypto device that enables access to all the kernelspace ciphers including the ARMv8 and NEON accelerated ciphers. However, a program would need to know ahead of time which accelerated cipher it intends to use. Otherwise, it defaults to the...

    [RT-AC86U] Accelerated crypto with /dev/crypto

    I have /dev/spu, it's already loaded. Is it open source? https://github.com/RMerl/asuswrt-merlin.ng/blob/master/release/src-rt-5.02hnd/kernel/linux-4.1/config_base.6a#L2827 Also, the CONFIG_BCM_CRYPTODEV setting doesn't appear to do anything, it doesn't make a /dev/crypto.

    [RT-AC86U] Accelerated crypto with /dev/crypto

    I've been trying to test openssl to use /dev/crypto, to access the accelerated ciphers of the RT-AC86U. These are kernel modules in the Linux mainline kernel, written in 64-bit assembler, intended for the ARMv8 cpu. However, it's kernelspace and I need a userspace interface such as /dev/crypto...

    Entware-3x for new HND platform (GT-AC5300 and RT-AC86U) with asuswrt-merlin firmware

    I just learnt that "-evp" tells openssl to use the AES hardware of the RT-AC86u. Booyah!! # /opt/bin/openssl speed -evp aes-256-cbc -elapsed You have chosen to measure elapsed time instead of user CPU time. Doing aes-256-cbc for 3s on 16 size blocks: 38323622 aes-256-cbc's in 3.03s Doing...

    Entware-3x for new HND platform (GT-AC5300 and RT-AC86U) with asuswrt-merlin firmware

    My RT-AC86U cpuinfo has "fp asimd evtstrm aes pmull sha1 sha2 crc32". I want to turn on all the bells and whistles. Have you tried "-mfpu=crypto-neon-fp-armv8" ?

    Entware-3x for new HND platform (GT-AC5300 and RT-AC86U) with asuswrt-merlin firmware

    Where is the Entware-3x config to do "-O3 hard float"? I will try re-compiling the repo this way. I hope it goes well. EDIT: is it this way? CONFIG_TARGET_OPTIMIZATION="-O3 -pipe -march=armv7-a -mtune=cortex-a9 -mfloat-abi=hard" # CONFIG_SOFT_FLOAT is not set

    Swap File Mount/Unmount

    Your swap file requires a clean filesystem (ext4, FAT32, etc.) whereas a swap partition does not. And when you use fstab, I think it's supposed to mount and un-mount automatically.

    Swap File Mount/Unmount

    I done it before, but I don't remember how exactly. When you have multiple USB storage devices that are partitioned differently. Maybe the first partition, /dev/sda1, will not always be swap space? It could be a data partition with important files, then you plug it in by mistake and Asuswrt...

    Entware-3x for new HND platform (GT-AC5300 and RT-AC86U) with asuswrt-merlin firmware

    FYI... My RT-AC86U firmware has the required 64-bit library /lib/aarch64/libgcc_s.so.1, from the Asuswrt toolchain. And I was a bit surprised when I ran hdparm, and it worked just fine!! However, I understand you don't want to link Entware programs against Asuswrt libraries. # ldd...
