| littlebobeep | shorne: Very interesting, which FPGAs have you worked with and what toolchains/bitsream formats do they work with? | 00:01 |
|---|---|---|
| zx2c4 | shorne: CC'd ya on https://lore.kernel.org/lkml/[email protected]/ since we talked aboutthis idea a few days ago | 00:35 |
| tpb | Title: [PATCH] init: call time_init() before rand_initialize() - Jason A. Donenfeld (at lore.kernel.org) | 00:35 |
| zx2c4 | turns out this actually makes a difference on other platforms too but the problem was being unnecessarily hidden by other things | 00:36 |
| zx2c4 | i still think it's cool to start the openrisc timer really early though as that one asm line does, so lets keep that | 00:37 |
| zx2c4 | "measures" bootup | 00:37 |

| shorne | zx2c4: yeah, I was thinking of moving the timer_init earlier too, but I figured that has more implecations so I thought its good to just start the OR1K timer right aways | 06:01 |
| shorne | I agree to keep the timer started | 06:02 |
| shorne | littlebobeep: I have run openrisc cores on xilinx and altera/intel fpga's | 06:02 |
| shorne | others have used lattice FPGA's | 06:02 |
| shorne | zx2c4: I am trying to fuzz this compiler/linker issue. If I add just the right amount of nops (each being 4 bytes) I can trigger it/fix it | 06:03 |
| shorne | trying to understand the pattern | 06:04 |

| zx2c4 | shorne: oh wow | 14:36 |
| zx2c4 | interesting | 14:37 |
| zx2c4 | so theory is holding up | 14:37 |

| shorne | zx2c4: yes, it would be good if I can do the same with a non-preempt kernel and prove its not preemption | 23:29 |
| shorne | but I am working on a small tool to extract the list of symbols that are changing with the nops | 23:30 |
