Quick run-down: 1. Reports surface that the Orange Box SrcDS (OBSrcDS from here on) fails on older processors. 2. Circumstantial evidence is shown that lack of SSE2 might lead to these errors. 3. Chris Green (Valve) states that SSE2 is not required (only plain SSE, available on P3s, is) as no compiler flags have been used to force it. 4. Chris returns with a message that he has been able to reproduce this and will have to look down into the guts of the assembly code to get the bug fixed. (No response from him since.) 5. Reports continue. 6. Alfred Reynolds (Valve, mailing list legend) says missing FCMOV extensions mean epic fail. 7. I read Intel and AMD processor manuals. They say that if feature flags "CMOV" and "FPU" are both enabled, the processor can do FCMOV. 8. People report that even though both flags are set on their machines, bad bone weight errors still occur for them. 9. I write an assembler program that exits with zero if one of the FCMOV instructions is executed, and, by definition, fails if the instruction is unknown to the processor. People try it out on their machines, and even though no Unknown Instruction error occurs, OBSrcDS still has bad bone weights.
And that's where the story pretty much ends. The culprit is probably lack of SSE2 and badly generated code. It's not known if it's a Valve or a GCC bug. ~~ Ondra On 06.11.07 20:35 Uhr, Some Llama wrote:
-- [ Picked text/plain from multipart/alternative ] Hey All, So I have a P3 linux server I run CS:S on and thought i'd dedicate it to TF2, read through some of the old postings to his mailing list and it looks like the P3 doesn't support some processor function the newer TF2 engine needs in order to run on Linux? Is that correct? Can someone please confirm? I'm getting the bad bone weights messages along with the errors at the end of the debug.log but looking through the postings it looks like the conversation died off after talk of support for FCMOV? Thanks for your time. llama
