SystemACE on Kernel 2.6

Hi Grant likely, I got kernel 2.6.20 from kernel.org and I want boot it on XUP Virtex II Pro University board. I edited the Makefile putting: ARCH? = ppc CROSS_COMPILE? = ppc_4xx- But I can't see anything about SystemACE driver on make menuconfig from this Kernel. How can I add SystemACE control

Re: Problems of using APU/FPU under linux

Sorry I didn't make myself clear. I just want to use FPU as a normal co-processor under Linux. I mean different programs and maybe multiple users, well, for single precision. So I think the exception handler really helps! Thank you Steve and John, I added the exception handler. It solved

Re: Problems of using APU/FPU under linux

Hi Shan, It's not clear what you're trying to do. If you have only one application using the FPU, and you're setting up the APU and FPU from that user application, I'm not sure if you need the FPU unavailable handler. If you're going to have multiple applications use the FPU, then you should us

Re: Problems of using APU/FPU under linux

No, actually I am using head_4xx.S and I cannot find FPU_UNAVAILABLE in there. Do I need to set it? And I commented out the _GLOBAL(giveup_fpu) in head_4xx.S because it has conflicts with fpu.S Shan On Apr 15, 2008, at 2:37 PM, Stephen Neuendorffer wrote: Shanyuan, Did you install th

Re: Problems of using APU/FPU under linux

Thank you, Yoshio!! I just applied the change, seems it works! But it doesn't work correctly. I mean it won't give me traps any more, but the answer is not correctly. I just tried to multiply two float numbers. But it gives me 0. The first time I change the reg.h was to enable apu enable,

io_block_mapping & ioremap question

Hi, I'm doing some work on 2.6.10, and got this problem: - there are some io_block_mapping calls in the setup_io_mapping callback, that use the BATs, and passing same va and pa each one. Problem arises later when vmallocs gets a a pointer within the mapped ranges. In other words, seems like

RTC no longer being updated in 2.6.16...

Disclaimer: I'm working on a new project here, so I'm not 100% up-to-date on the system as a whole. I've been tasked to find out why our RTC clock is not being updated after suynching with a NTP timesource. In our previous release, the RTC seemed to be updated every 11 minutes via the timer_in

[PATCH] LLTEMAC resource end address

Hi, We have a design with LLTEMAC0 using channels 0 & 1, and LLTEMAC1 using channel 0. When the Linux kernel boots, we had the following error message: --- Registering device xilinx_lltemac:0 Registering device xilinx_lltemac:1 xilinx_lltemac.1: failed to claim resource 0 cannot register dev xili
