2012-11-28Remove assembly coded log2 functionRonald G. Minnich
As we move to supporting other systems we need to get rid of assembly where we can. The log2 function in src/lib is identical to the assembly one (tested for all 32-bit signed integers :-) and takes about 10 ns to run as opposed to 5ns for the non-portable assembly version. While speed is good, I think we can spare the 15 ns or so we add to boot time by using the C version only. Change-Id: Icafa565eae282c85fa5fc01b3bd1f110cd9aaa91 Signed-off-by: Ronald G.

2012-11-13cros: Inform U-Boot via fake gpio when VGA Option ROM is loadedBill Richardson
This prepares the way for vboot to inform coreboot when it needs the VGA Option ROM loaded. Coreboot can't always know when it's needed (with keyboard-based dev-mode, coreboot can't tell if we're in dev-mode or not). By the time we get to U-Boot, it's too late, so we need two extra bits - one for vboot to tell coreboot to load the Option ROM and another for coreboot to let vboot know it's been done. This change sets up the communication, but doesn't act on it just yet. Even with this CL we always load the VGA Option ROM, so there's nothing to test. There should be no user-visible change.

2012-11-12oprom: Ensure that mode information is valid before putting it in the tables.Gabe Black
At least when CONFIG_CHROMEOS is turned on, it's possible for CONFIG_FRAMEBUFFER_KEEP_VESA_MODE to be set but for there not to be any valid information to put into the framebuffer coreboot table. That means that what's put in there is junk, probably all zeroes from the uninitialized global variable the mode information is stored in (mode_info). When a payload uses libpayload and turns on the coreboot framebuffer console, that console will attempt to scroll at some point and decrease the cursor's y coordinate until it is less than the number of rows claimed by the console. The number of rows is computed by taking the vertical resolution of the framebuffer and dividing it by the height of the font. Because the mode information was all zeroes, the coreboot table info is all zeroes, and that means that the number of rows the console claims is zero. You can't get the unsigned y coordinate of the cursor to be less than zero, so libpayload gets stuck in an infinite loop. The solution this change implements is to add a new function, vbe_mode_info_valid, which simply returns whether or not mode_info has anything in it. If not, the framebuffer coreboot table is not created, and libpayload doesn't get stuck.

2012-08-04Make the device tree available in the rom stageStefan Reinauer
We thought about two ways to do this change. The way we decided to try was to 1. drop all ops from devices in romstage 2. constify all devices in romstage (make them read-only) so we can compile static.c into romstage 3. the device tree "devices" can be used to read configuration from the device tree (and nothing else, really) 4. the device tree devices are accessed through struct device * in romstage only. device_t stays the typedef to int in romstage 5. Use the same static.c file in ramstage and romstage We declare structs as follows: ROMSTAGE_CONST struct bus dev_root_links[]; ROMSTAGE_CONST is const in romstage and empty in ramstage; This forces all of the device tree into the text area. So a struct looks like this: static ROMSTAGE_CONST struct device _dev21 = { #ifndef __PRE_RAM__ .ops = 0, #endif .bus = &_dev7_links[0], .path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}}, .enabled = 0, .on_mainboard = 1, .subsystem_vendor = 0x1ae0, .subsystem_device = 0xc000, .link_list = NULL, .sibling = &_dev22, #ifndef __PRE_RAM__ .chip_ops = &southbridge_intel_bd82x6x_ops, #endif .chip_info = &southbridge_intel_bd82x6x_info_10, .next=&_dev22 }; Change-Id: I722454d8d3c40baf7df989f5a6891f6ba7db5727 Signed-off-by: Ronald G.

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.

2011-01-13Improve compatibility of YABEL with real-world VGABIOSesPatrick Georgi
Some of them do weird things to the option rom region (mapping registers there or so) which failed as we handled these memory region in emulation. As they were copied back to real memory after the emulation was done, we can just as well use real memory directly for these regions. This affects IVT, BDA, and option ROM space.

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.

The following functions are moved to devices/device_util.c: - ram_resource() - tolm_test() - find_pci_tolm() There are only two tolm_test() / find_pci_tolm() which differ from the defaults, one of them can easily be eliminated in a follow-up patch, maybe even both, but for now keep it simple and only eliminate the majority.

at the same time let the user specify sources instead of object files: - objs becomes ramstage-srcs - initobjs becomes romstage-srcs - driver becomes driver-srcs - smmobj becomes smm-srcs The user servicable parts are named accordingly: ramstage-y, romstage-y, driver-y, smm-y Also, the object file names are properly renamed now, using .ramstage.o, .romstage.o, .driver.o, .smm.o suffixes consistently.
