RE: Makefile changes for symbols

Steve, What version of Source point are you using? The symbols are coming in but SourcePoint doesn't allow me to reference the source files. I mapped the linuxbios directory on my Win2000 system for SourcePoint to access. (I have samba running on my linux system) I just need to get SourcePoint working. Thanks, Rod -----Original Message----- From: Kimball, Stephen Sent: Wednesday, October 20, 2004 1:04 PM To: Kittleson, Rodney C.; linuxbios(a)clustermatic.org Cc: Jeff_Pitts(a)arium.com Subject: RE: Makefile changes for symbols The file under your target in normal/linuxbios_c.o seems to have all the symbols if you add "-gdwarf-2" to the $CFLAGS in the Makefile. Then when you open the first C module the SourcePoint software asks where the file exists, after you tell SourcePoint it seems to find the rest by itself. I recreated the same Linux directory structure on Windows. Thanks Rod! Steve -----Original Message----- From: Kittleson, Rodney C. Sent: Wednesday, October 20, 2004 11:47 AM To: Kimball, Stephen; linuxbios(a)clustermatic.org Subject: RE: Makefile changes for symbols Linuxbios_c, from the build directory, can be sucked into Sourcepoint to extract the symbols. This allows the disassembled instructions to display the symbols inline. It makes it easier to set breakpoints and follow the code, but it's a far cry from source level debugging. I haven't attempted to link the source with sourcepoint yet. I may try it later this week, let me know if you have any success. Rod -----Original Message----- From: Kimball, Stephen Sent: Tuesday, October 19, 2004 3:33 PM To: linuxbios(a)clustermatic.org Subject: Makefile changes for symbols Can someone give me the Makefile changes to make a LinuxBIOS with symbols? I tried adding "-gdwarf-2" to CFLAGS, but I'm not sure where the unstripped output would be. Are there any features in the code that are useful in debugging LinuxBIOS? Any defines that should change as well? Someone must have some experience with source code level debugging of LinuxBIOS with an American Arium ECM-50. Thanks.

I can't test that it works but I can test that the bits are getting set by running lspci. And that is how I tested. The bus master bit is still getting set. I just move the location. Eric

Why just set subsystem id, in amd_8111.c enable_dev function? That would more easy. Need one switch case to figure out different reg position.

I hope in the mtrr.c for K8 instead of hack with the mem_map we have: setup_mtrr() { if (search_for_vga_device_on_the_tree() == FOUND) { enable_rd_wr_mem_in_fixed_mtrr(); clear_rd_wr_mem_for_legacy_vga_buffer(); set_IORR_to_AGP_aperture(); } else { disable_rd_wr_mem(); } do_some_other_thigs(); } And the code is executed on each processors.

You may remove .enable = amd8111_enable, It will be called twice. One in enable_dev. -----Original Message----- From: ebiederman(a)lnxi.com [mailto:ebiederman@lnxi.com] Sent: Thursday, October 21, 2004 10:46 AM To: YhLu; Li-Ta Lo Cc: LinuxBIOS Subject: Re: Freebios2 recovery progress...

Or more likely src/mainboarod/???/???/Options.lb src/devices/pci_device.c:pci_dev_enable_resources() calls dev->ops->pci_ops->set_subsystem() when the device dev->on_mainboard is true. In turn config.g sets that in static.c for all devices in the static tree. I believe those are the correct semantics. That the subsystem is essentially an identifier for the board the chips are sitting on. The values are come from: Look at MAINBOARD_PCI_SUBSYSTEM_VENDOR_ID and MAINBOARD_SUBSYSTEM_DEVICE_ID. So for the onboard scsi case you likely need to have a driver for the onboard scsi device that implements the set_subsystem method because there is not a generic way of doing that. Eric

Eric, You overwrite some lines in amd8131.... /* We have to enable MEM and Bus Master for IOAPIC */ value = pci_read_config32(dev, 0x4); value |= 6; pci_write_config32(dev, 0x4, value); Regards YH static void ioapic_enable(device_t dev) { uint32_t value; value = pci_read_config32(dev, 0x44); if (dev->enabled) { value |= ((1 << 1) | (1 << 0)); } else { value &= ~((1 << 1) | (1 << 0)); } pci_write_config32(dev, 0x44, value); /* We have to enable MEM and Bus Master for IOAPIC */ value = pci_read_config32(dev, 0x4); value |= 6; pci_write_config32(dev, 0x4, value); } -----Original Message----- From: ebiederman(a)lnxi.com [mailto:ebiederman@lnxi.com] Sent: Thursday, October 21, 2004 4:08 AM To: LinuxBIOS Subject: Freebios2 recovery progress... I have managed to get another chunk of merging and bug fixing done tonight. I now have pci subsystem vendor and subsystem id's being set on the arima hdama, so the board is now identifiable with lspci. I have bumped the LinuxBIOS minor version so we can track these changes. All of the superio chips should not work or at least be very close except the weird via superio/pci hybrid that I could not make sense of. I have changed all of the references to chip_control to chip_operations. And fixed up the usage while I was in the neighborhood if I could clearly see what the fix should be. So Config.lb for most of the Opteron ports should work, or at least be very close now. It is time for me to break off and head home.
