Pixel Watch - Dump boot_a/boot_b from fastboot using sha1sum and ramdump memes
# Dump partitions from the Pixel Watch's fastboot using `oem sha1sum`
# and `oem ramdump` memes.
#
# Currently the first 8 bytes aren't bruteforced, but they ~can be.
# Doesn't really matter though because the first 8 bytes is the "ANDROID!" magic
# for boot partitions.

Linux VFIO KVM Passthrough with AMD Radeon card -- Solution for dmesg error «No more image in the PCI ROM» -- VFIO single graphics card bootup

If you have a black screen when trying to boot your guest OS via qemu/kvm with passthrough for your AMD Radeon card (in my case RX 480/590 or POLARIS10) and nothing is working, and you are able to ssh into the host while the virtualization is running or afterwards and get something like this via dmesg:

...
vfio_ecap_init: hiding ecap 0x19@0x270
...
vfio-pci 0000:03:00.0: No more image in the PCI ROM
...

Then the solution is to boot Linux through pure EFI; the problem is enabling CSM and then either booting the host system through a legacy BIOS bootloader or EFI. TL;DR: Disable CSM, ensure you've a proper EFI boot chain first. Then it will work straight away.

PC game port best practices

  • Always use scancodes for keyboard game input to make WASD work even under DVORAK or AZERTY layouts; you care about the key position, not the meaning.

    • Use keycodes to retrieve the actual key meaning/value when you need actual text input.

  • Support paths bigger than 256 characters (MAX_PATH), this should no longer be a limitation. Launch your game from a folder or symlink with hundreds of characters; this can be combined with the next point.

  • Try your game with a special username/user account that has international characters and spaces, like Ñame áôeÓ®他の詩っステム　元バ to ensure you are handling Unicode paths correctly. This is especially tricky on Windows, where you will have to wrap fopen() with the UTF-16 version because the normal version does not understand UTF-8.

    • Very often players with non-English names won't be able to save under AppData or their home directory otherwise.

  • On Windows you should store your savegames under the special %USERPROFILE%\Saved Games folder, use a dynamica

ARM’s Scalable Vector Extensions: A Critical Look at SVE2 For Integer Workloads

ARM’s Scalable Vector Extensions: A Critical Look at SVE2 For Integer Workloads

Scalable Vector Extensions (SVE) is ARM’s latest SIMD extension to their instruction set, which was announced back in 2016. A follow-up SVE2 extension was announced in 2019, designed to incorporate all functionality from ARM’s current primary SIMD extension, NEON (aka ASIMD).

Despite being announced 5 years ago, there is currently no generally available CPU which supports any form of SVE (which excludes the [Fugaku supercomputer](https://www.fujitsu.com/global/about/innovation/

Shift-based DFAs

A traditional table-based DFA implementation looks like this:

uint8_t table[NUM_STATES][256]

uint8_t run(const uint8_t *start, const uint8_t *end, uint8_t state) {
    for (const uint8_t *s = start; s != end; s++)
        state = table[state][*s];
    return state;
}
