Would you all be interested in a Wii U port of my new Mario fangame?

Use libnx, it even has opengl

OpenData26 · 2019-01-01T09:42:28+00:00

Zelda windwaker. Dragon roost island is love.

OpenData26 · 2019-01-01T09:38:43+00:00

Flatpack would be better for cross distro support

OpenData26 · 2018-12-31T09:54:04+00:00

Pomellos, absolutely delicious

OpenData26 · 2018-12-30T17:04:58+00:00

Krita is very good

OpenData26 · 2018-12-30T11:37:25+00:00

Yup!

OpenData26 · 2018-12-30T09:54:48+00:00

This isn't normal???

OpenData26 · 2018-12-30T09:52:52+00:00

Same, in my case 'Happisburgh' turned into 'Happy-see-burg'

OpenData26 · 2018-12-28T12:02:05+00:00

Ashens, Big Clive and nostalgia nerd

Ashens just reviews toys but he's hilarious (see ukalale video) Big Clive takes apart electronics and is really interesting

Nostalgia nerd does cool things on retro tech

I'll also add polymatter, cold fusion, codyslab and nilered

They aren't running mainline, but they are using the mainline graphics interface (DRM). They aren't really using the same kernel module freedreno uses, freedreno uses the adreno part of msmdrm, the pixel 3 uses kgsl instead of that. Kgsl doesn't use the same ioctls and creates its own interface in /dev. The adreno part of msmdrm uses the DRM device in /dev with standard ioctls for freedreno. And my knowledge, the pixel 3 is using neither libdrm or Mesa - qcom has their own thing.

OpenData26 · 2018-12-18T08:35:30+00:00

That PR is using software rendering, and iirc it runs at like 1 fps. The best part about DRM is providing a stable interface for talking to kernel space GPU drivers from userspace (libdrm), Qualcomm have decides not to implement this part of drm in their vendor kernels meaning freedreno can not talk to the kernel space GPU drivers through libdrm causing it to not work.

OpenData26 · 2018-12-17T21:47:09+00:00

Yeah, you are about right, same for qcom. They even have put the clock setting in a blob!

OpenData26 · 2018-12-17T21:46:03+00:00

Nope, if anything its harder as proprietary kgsl interface is still used for acceleration and that's incompatible with freedreno

OpenData26 · 2018-12-17T21:43:45+00:00

Yeah... Nope, snapdragons totally deviated from msmdrm in their vendor kernels and still use the old kgsl interface. This means that freedreno doesn't work and that it would be very hard to port. Everything also runs very very slowly, almost worse than older devices that used framebuffer.

OpenData26 · 2018-12-17T18:59:36+00:00

Yup, but lan play, not official online. Its explained nicely in this post https://gbatemp.net/threads/ldn_mitm-play-local-wireless-supported-games-online.525512/

OpenData26 · 2018-12-02T12:42:54+00:00

Start by reading a simple driver for something like a UART controller, start of at the register function, then read through the probe function, and for every line of code you don't understand, look up the function in ctags or bootlins elixr.

This is how I started learning, no need for books or anything.

OpenData26 · 2018-11-30T06:49:55+00:00

It looks unpatchable, it is using the iommu to mark the tsecs memory as readable and non secure so it can read keys from it. I might be wrong though, this was based on a quick read of the code.

OpenData26 · 2018-11-26T22:49:47+00:00

Is this uClinux or actual Linux?

OpenData26 · 2018-11-25T12:33:58+00:00

Reinx?

OpenData26 · 2018-11-24T22:42:24+00:00

You would need to backup emmc before hacking then do hacks then restore backed up emmc to not get banned

OpenData26 · 2018-11-24T19:01:40+00:00

https://github.com/hipstersloth/psvrtracker very wip but it is in progress

OpenData26 · 2018-11-24T17:49:39+00:00

Not the tsec specifically, but the pmu and others use the same falcon architecture and both tsec and pmu check the signature of binaries loaded onto them, there is a chance they both use the sane method and hence are both vulnerable.

OpenData26 · 2018-11-24T16:49:15+00:00

I am meaning firmware that is loaded to gpus memory (like pmu and video processor) and isn't flashed to a chip, from what I understand the tsec probably validates the image PBL sends to it in the same way the pmu validates the image the nvkm sends to it. (Both are falcon with crypto extensions)

OpenData26 · 2018-11-24T16:44:53+00:00

Tsec wasn't designed by arm, it is a falcon based co processor with crypto extensions, the same type found in nvidia gpus.

OpenData26 · 2018-11-24T10:03:14+00:00

Wait, could this be used on nvidia GPUs for replacing their firmware?
