03:57:41 <gitomat> [illumos-gate] 17919 MAC softring (set) status and types should be enums and documented -- Kyle Simpson <kyle⊙oc>
13:48:46 <szilard> Wow, this is sounds great: https://github.com/LuminousMonkey/xf86-video-illumosfb
13:49:08 <szilard> Provides an unaccelerated framebuffer driver for running a 2D X11 desktop on illumos systems where no native GPU driver exists (e.g. Nvidia Blackwell, recent AMD, Intel Arc). Works with any system that exposes a UEFI GOP framebuffer via /dev/fb0 through the kernel's gfxp_bitmap driver.
14:09:05 <jbk> hrm.. not a huge deal, but all of that pointer indirection and feature detection might be able to be replaced with linker capabilities...
14:10:23 <jbk> unfortunately, they're not well known, but are kinda neat
14:11:10 <jbk> (basically you can provide different implementations of the same function using different CPU features, and the linker will pick the 'best' one)
14:19:04 <jbk> i'm handwaving a bit, but that's the basic idea
20:13:23 <richlowe> symbol caps in the kernel would require krtld support
20:13:31 <richlowe> (so would object caps, but I'm going to assume nobody wants those)
20:16:38 <jbk> it's an x86 driver through, not a kernel driver
20:16:48 <jbk> so userland
20:17:18 <jbk> so presumably if it's built as an .so, it'd work...
20:17:46 <jbk> granted, I'm not sure how challenging it'd be to build it with autoconf
20:18:03 <richlowe> oh I somehow thought you were looking at the network performance stuff out of oxide
20:18:27 <jbk> no i was talking about the xf86-video-illumosfb driver
20:18:50 <jbk> i took a look and it's using a function pointer to pick an optimized 'copy' routine based on avx support
20:20:11 <richlowe> at least it's not STT_GNU_IFUNC
20:20:23 <richlowe> which see, if you have the stomach
20:20:38 <Reinhilde> :o
20:21:36 <jbk> is that the gcc 'dispatch a function based on cpu capabilities' bit?
20:27:59 <richlowe> jbk: that's the GNU "bind a function based on the runtime linker calling a user-function that chooses"
20:28:14 <richlowe> it's "more general"
20:31:36 <jbk> oh yeah
20:59:27 <jbk> rmustacc: should https://github.com/illumos/illumos-gate/blob/master/usr/src/uts/i86pc/io/pci/pci_prd_i86pc.c#L797-L811 be using pci_prd_upcalls->pru_bus2dip_f() there (or any reason not to do that you can think of?)
