2012-03-30Prepare the BIOS data areas before device init.Duncan Laurie
Since we do not run option roms in normal mode nothing was initializing the BDA/EBDA and yet Linux depends very much on it having sane values here. For the most part the kernel tries to work around this not being initialized, but every once in awhile (1/300 boots or so) it would end up reading something that looked sane from BDA but was not and then it would panic. In this change the EBDA is unconditionally setup before devices are initialized. I'm not set on the location in dev_initialize() but there does not seem to be another place to hook it in so that it runs just once for ALL platforms regardless of whether they use option roms or not. (possibly hardwaremain?) The EBDA setup code has been moved into its own location in arch/x86/lib/ebda.c so it can be compiled in even if the option rom code is not. The low memory size is still set to 1MB which is enough to make linux happy without having to hook into each mainboard to get a more appropriate value. The setup_ebda() function takes inputs so it could be changed for a mainboard if needed. OLD/BROKEN would read garbage. Examples from different boots: ebda_addr=0x75e80 lowmem=0x1553400 ebda_addr=0x5e080 lowmem=0x3e51400 ebda_addr=0x7aa80 lowmem=0x2f8a800 NEW/FIXED now reads consistent values: ebda_addr=0xf6000 lowmem=0x100000 Change-Id: I6cb79f0e3e43cc65f7e5fe98b6cad1a557ccd949 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: http://review.coreboot.org/769 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-03-24printf: Remove some L modifier usesPatrick Georgi
We use the L modifier in a non-standard way (for long long instead of long double, which we have no business with). clang complains, to reduce its use, to make emulation/qemu-x86 happier. Long term, we should consider eliminating public uses of 'L' (but internal use in vtxprintf to denote long long is fine) Change-Id: If9a17d9ae9925cdc8736445e7d5eedc59c7028c6 Signed-off-by: Patrick Georgi <patrick@georgi-clan.de> Reviewed-on: http://review.coreboot.org/781 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

2012-02-07Fix multipleVGA cards resource conflict on WindowsKerry Sheh
If multiple VGA-compatible legacy graphic cards decode the IO range 3B0-3BB, 3C0-3DF and MEM range A00000-BFFFF. Windows 7 complain a resource conflict, so only one VGA card can works at the same time. There is a discussion in coreboot mail list before, please reference thread: "how to prevent legacy resource conflictwith multipleVGA cards" http://www.coreboot.org/pipermail/coreboot/2010-October/061508.html Linux using VGA Arbiter module(vgaarb) to resolve this resource conflict, Please see the following linux dmesg log, more information can be found in Linux source dir Documentation/vgaarbiter.txt. But it seems that windows don't dealwith this conflict. ~# dmesg | grep -i vgaarb [ 0.774076] vgaarb: device added: PCI:0000:00:01.0,decodes=io+mem,owns=io+mem [ 0.776065] vgaarb: device added: PCI:0000:01:00.0,decodes=io+mem,owns=none,l [ 0.780051] vgaarb: loaded [ 0.784049] vgaarb: bridge control possible 0000:01:00.0 [ 0.788050] vgaarb: bridge control possible 0000:00:01.0 For the second legacy graphic device, coreboot already disabled the IO and MEM decode in function set_vga_bridge_bits(). But it will be enabled again in function pci_set_resource(), if the second legacy vga-compatible graphic device take any IO/MEM resources. Following log printed by enable_resources() shows the problem: ...snip...

The IO & MEM decoding on the second vga graphic device should be disabled. Please reference PCI spec. section 3.10 in detail. set_vga_bridge_bits() would do this work for us, it did the right thing, but was put to the wrong place, the setting would be overwritten by assign_resources() later. In order to make sure the set_vga_bridge_bits() setting not be overwritten by others, moving the call of set_vga_bridge_bits() to the end of dev_configure(), instead of at the beginning. This patch resolved the dual graphic cards resource conflict in windows7, multiple vga-compatible graphic cards can work together in windows7.

2010-11-22Printing coreboot debug messages on VGA console is pretty much useless, sinceStefan Reinauer
initializing VGA happens pretty much as the last thing before starting the payload. Hence, drop VGA console support, as we did in coreboot v3. - Drop VGA and BTEXT console support. Console is meant to be debugging only, and by the time graphics comes up 99% of the risky stuff has already happened. Note: This patch does not remove hardware init but only the actual output functionality. The ragexl driver needs some extra love, but that's for another day - factor out die() and post() - drop some leftover RAMBASE < 0x100000 checks.

2009-07-02Move the v3 resource allocator to v2.Myles Watson
Major changes: 1. Separate resource allocation into: A. Read Resources B. Avoid fixed resources (constrain limits) C. Allocate resources D. Set resources Usage notes: Resources which have IORESOURCE_FIXED set in the flags constrain the placement of other resources. All fixed resources will end up outside (above or below) the allocated resources. Domains usually start with base = 0 and limit = 2^address_bits - 1. I've added an IOAPIC to all platforms so that the old limit of 0xfec00000 is still there for resources. Some platforms may want to change that, but I didn't want to break anyone's board. Resources are allocated in a single block for memory and another for I/O. Currently the resource allocator doesn't support holes. Signed-off-by: Myles Watson <mylesgw@gmail.com> Acked-by: Ronald G.

2004-10-30- To reduce confuse rename the parts of linuxbios bios that run fromEric Biederman
ram linuxbios_ram instead of linuxbios_c and linuxbios_payload... - Reordered the linker sections so the LinuxBIOS fallback image can take more the 64KiB on x86 - ROM_IMAGE_SIZE now will work when it is specified as larger than 64KiB. - Tweaked the reset16.inc and reset16.lds to move the sanity check to see if everything will work. - Start using romcc's built in preprocessor (This will simplify header compiler checks) - Add helper functions for examining all of the resources - Remove debug strings from chip.h - Add llshell to src/arch/i386/llshell (Sometime later I can try it...) - Add the ability to catch exceptions on x86 - Add gdb_stub support to x86 - Removed old cpu options - Added an option so we can detect movnti support - Remove some duplicate definitions from pci_ids.h - Remove the 64bit resource code in amdk8/northbridge.c in preparation for making it generic - Minor romcc bug fixes git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1727 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2004-10-27sizeram removal/conversion.Eric Biederman
- mem.h and sizeram.h and all includes killed because the are no longer needed. - linuxbios_table.c updated to directly look at the device tree for occupied memory areas. - first very incomplete stab a converting the ppc code to work with the dynamic device tree - Ignore resources before we have read them from devices, (if the device is disabled ignore it's resources). - First stab at Pentium-M support - add part/init_timer.h making init_timer conditional until there is a better way of handling it. - Converted all of the x86 sizeram to northbridge set_resources functions. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1722 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2004-10-21- Bump the LinuxBIOS major versionEric Biederman
- Rename chip_config chip_operations throughout the tree - Fix Config.lb on most of the Opteron Ports - Fix the amd 8000 chipset support for setting the subsystem vendor and device ids - Add detection of devices that are on the motherboard (i.e. In Config.lb) - Baby step in getting the resource limit handling correct, Ignore fixed resources - Only call enable_childrens_resources on devices we know will have children For some busses like i2c it is non-sense and we don't want it. - Set the resource limits for pnp devices resources. - Improve the resource size detection for pnp devices. - Added a configuration register to amd8111_ide.c so we can enable/disable individual ide channels - Added a header file to hold the prototype of isa_dma_init - Fixed most of the superio chips so the should work now, the via superio pci device is the exception. - The code compiles and runs so it is time for me to go to bed. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1698 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

2004-03-11- Moved hlt() to it's own header.Eric Biederman
- Reworked pnp superio device support. Now complete superio support is less than 100 lines. - Added support for hard coding resource assignments in Config.lb - Minor bug fixes to romcc - Initial support for catching the x86 processor BIST error codes. I've only seen this trigger once in production during a very suspcious reset but... - added raminit_test to test the code paths in raminit.c for the Opteron - Removed the IORESOURCE_SET bit and added IORESOURCE_ASSIGNED and IORESOURCE_STORED so we can tell what we have really done. - Added generic AGP/IOMMU setting code to x86 - Added an implementation of memmove and removed reserved identifiers from memcpy - Added minimal support for booting on pre b3 stepping K8 cores - Moved the checksum on amd8111 boards because our default location was on top of extended RTC registers - On the Hdama added support for enabling i2c hub so we can get at the temperature sensors. Not that i2c bus was implemented well enough to make that useful. - Redid the Opteron port so we should only need one reset and most of memory initialization is done in cpu_fixup. This is much, much faster. - Attempted to make the VGA IO region assigment work. The code seems to work now... - Redid the error handling in amdk8/raminit.c to distinguish between a bad value and a smbus error, and moved memory clearing out to cpufixup. - Removed CONFIG_KEYBOARD as it was useless. See pc87360/superio.c for how to setup a legacy keyboard properly. - Reworked the register values for standard hardware, moving the defintions from chip.h into the headers of the initialization routines. This is much saner and is actually implemented. - Made the hdama port an under clockers BIOS. I debuged so many interesting problems. - On amd8111_lpc added setup of architectural/legacy hardware - Enabled PCI error reporting as much as possible. - Enhanded build_opt_tbl to generate a header of the cmos option locations so that romcc compiled code can query the cmos options. - In romcc gracefully handle function names that degenerate into function pointers - Bumped the version to 1.1.6 as we are getting closer to 2.0 TODO finish optimizing the HT links of non dual boards TODO make all Opteron board work again TODO convert all superio devices to use the new helpers TODO convert the via/epia to freebios2 conventions TODO cpu fixup/setup by cpu type git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1390 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
