D3D12 CPU Efficiency

@newincpp Checks out. Byte 0 for your CPU endianness would be where 0xRR is. You read the hex value right to left, but the Vulkan format left to right.

I feel very dumb today, Did I miss something on GPU endianess or something ?
I'm uploading a uint32 buffer to a VkImage and it looks like its 0xaabbggrr instead of 0xrrggbbaa despite a VK_FORMAT_R8G8B8A8_UNORM 🤔

I have shared it in the past but it is worth re-sharing this great collection of resources on GPU optimisation: gist.github.com/silvesthu/505c…

“Low-level thinking in high-level shading languages” is in my top 3 most influential presentations, one that changed the way I think about shader programming. 2023 was the 10th anniversary so I tried a quick refresh and discussed developments since. interplayoflight.wordpress.com/2023/12/29/low…

Great explainer of occupancy, also includes some new info I haven't seen elsewhere, eg the 16 waves max occupancy for RDNA2/3 (compared to RDNA's 20) and the inter-wave barrier needed for threadgroup with 2+ waves and how it affects occupancy gpuopen.com/learn/occupanc…

Here is a new blog post of mine about fibers.
Hopefully, it could be helpful to someone who is interested in learning the topic.

@miniciv @PCBWayOfficial It's called a TVS (transient voltage suppression) diode.
On @digikey - digikey.com/en/products/de…
Meant to cut down on ESD effects.
The board design is available here: github.com/JeremySCook/Ki…

Latest @Raspberry_Pi RP2040 design appears to get power correctly. Now to figure out how to get it blinking some LEDs under @CircuitPython

I’ve written a small library that provides an assert-like macro in HLSL shaders that triggers a GPU memory page fault. Together with Radeon GPU Detective, it may be useful for debugging. github.com/sawickiap/Shad…

The @AMDRadeon Developer Tool Suite has a new member: Radeon #GPU Detective (RGD) 🕵️
RGD is a tool for post-mortem analysis of GPU crashes so you can:
🎆 Capture and analyze crash dumps
🎆 Narrow down the root cause of a crash
Take a look now! #D3D12
