2016-01-28Move object files to $(obj)/<class>/Nico Huber
Instead of tagging object files with .<class>, move them to a <class> directory below $(obj)/. This way we can keep a 1:1 mapping between source- and object-file names. The 1:1 mapping is a prerequisite for Ada, where the compiler refuses any other object-file name. Tested by verifying that the resulting coreboot.rom files didn't change for all of Jenkins' abuild configurations.

2016-01-28Makefile: Make full use of src-to-obj macroNico Huber
There were several spots in the tree where the path to a per class object file was hardcoded. To make use of the src-to-obj macro for this, it had to be moved before the inclusion of subdirs. Which is fine, as it doesn't have dependencies beside $(obj). Tested by verifying that the resulting coreboot.rom files didn't change for all of Jenkins' abuild configurations.

2015-10-29smmhandler: on i945..nehalem, crash if LAPIC overlaps with ASEGPatrick Georgi
This mitigates the Memory Sinkhole issue (described on https://github.com/xoreaxeaxeax/sinkhole) by checking for the issue and crashing the system explicitly if LAPIC overlaps ASEG. This needs to happen without a data access (only code fetches) because data accesses could be tampered with. Don't try to recover because, if somebody tried to do shenanigans like these, we have to expect more. Sandybridge is safe because it does the same test in hardware, and crashes. Newer chipsets presumably do the same. This needs to be extended to deal with overlapping TSEG as well.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>
2015-05-20build system: use archives, not linker action to shorten command linesPatrick Georgi
Intermediate linking may distort linker behavior (in particular related to weak symbols). The idea is that archives are closer to 'just a list of object files', and ideally makes the linker more predictable. Using --whole-archive, the linker doesn't optimize out object files just because their symbols were already provided by weak versions. However it shouldn't be used for libgcc, because that one has some unexpected side-effects.

2015-04-06New mechanism to define SRAM/memory map with automatic bounds checkingJulius Werner
This patch creates a new mechanism to define the static memory layout (primarily in SRAM) for a given board, superseding the brittle mass of Kconfigs that we were using before. The core part is a memlayout.ld file in the mainboard directory (although boards are expected to just include the SoC default in most cases), which is the primary linker script for all stages (though not rmodules for now). It uses preprocessor macros from <memlayout.h> to form a different valid linker script for all stages while looking like a declarative, boilerplate-free map of memory addresses to the programmer. Linker asserts will automatically guarantee that the defined regions cannot overlap. Stages are defined with a maximum size that will be enforced by the linker. The file serves to both define and document the memory layout, so that the documentation cannot go missing or out of date. The mechanism is implemented for all boards in the ARM, ARM64 and MIPS architectures, and should be extended onto all systems using SRAM in the future. The CAR/XIP environment on x86 has very different requirements and the layout is generally not as static, so it will stay like it is and be unaffected by this patch (save for aligning some symbol names for consistency and sharing the new common ramstage linker script include). BUG=None TEST=Booted normally and in recovery mode, checked suspend/resume and the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and Pit. Compiled Ryu, Storm and Urara, manually compared the disassemblies with ToT and looked for red flags.

2014-08-11coreboot classes: Add dynamic classes to corebootFurquan Shaikh
Provide functionality to create dynamic classes based on program name and architecture for which the program needs to be compiled/linked. define_class takes program_name and arch as its arguments and adds the program_name to classes-y to create dynamic class. Also, compiler toolset is created for the specified arch. All the files for this program can then be added to program_name-y += .. Ensure that define_class is called before any files are added to the class. Check subdirs-y for order of directory inclusion. One such example of dynamic class is rmodules. Multiple rmodules can be used which need to be compiled for different architectures. With dynamic classes, this is possible.

2014-05-06Introduce stage-specific architecture for corebootFurquan Shaikh
Make all three coreboot stages (bootblock, romstage and ramstage) aware of the architecture specific to that stage i.e. we will have CONFIG_ARCH variables for each of the three stages. This allows us to have an SOC with any combination of architectures and thus every stage can be made to run on a completely different architecture independent of others. Thus, bootblock can have an x86 arch whereas romstage and ramstage can have arm32 and arm64 arch respectively. These stage specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain and compiler flags for every stage. These options can be considered as either arch or modes eg: x86 running in different modes or ARM having different arch types (v4, v7, v8). We have got rid of the original CONFIG_ARCH option completely as every stage can have any architecture of its own. Thus, almost all the components of coreboot are identified as being part of one of the three stages (bootblock, romstage or ramstage). The components which cannot be classified as such e.g. smm, rmodules can have their own compiler toolset which is for now set to *_i386. Hence, all special classes are treated in a similar way and the compiler toolset is defined using create_class_compiler defined in Makefile. In order to meet these requirements, changes have been made to CC, LD, OBJCOPY and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others. Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the toolsets are defined using create_class_compiler. Few additional macros have been introduced to identify the class to be used at various points, e.g.: CC_$(class) derives the $(class) part from the name of the stage being compiled. We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER as they do not make any sense for coreboot as a whole. All these attributes are associated with each of the stages.

2013-03-14x86: SMM Module SupportAaron Durbin
Add support for SMM modules by leveraging the RMODULE lib. This allows for easier dynamic SMM handler placement. The SMM module support consists of a common stub which puts the executing CPU into protected mode and calls into a pre-defined handler. This stub can then be used for SMM relocation as well as the real SMM handler. For the relocation one can call back into coreboot ramstage code to perform relocation in C code. The handler is essentially a copy of smihandler.c, but it drops the TSEG differences. It also doesn't rely on the SMM revision as the cpu code should know what processor it is supported. Ideally the CONFIG_SMM_TSEG option could be removed once the existing users of that option transitioned away from tseg_relocate() and smi_get_tseg_base(). The generic SMI callbacks are now not marked as weak in the declaration so that there aren't unlinked references. The handler has default implementations of the generic SMI callbacks which are marked as weak. If an external compilation module has a strong symbol the linker will use that instead of the link one. Additionally, the parameters to the generic callbacks are dropped as they don't seem to be used directly. The SMM runtime can provide the necessary support if needed.

2012-07-24SMM: Add heap region and move C handler higher in regionDuncan Laurie
In order to support SPI and ELOG drivers the SMM region needs to be able to be larger than the previous allocation below 0x7400. Now that we have support for 4M TSEG we do not need to live in this region. This change adds a 16KB heap region abofe the save state area at TSEG+64KB and moves the C handler above this. The heap region is then available for malloc and the C handler can grow to support flash and event log features. While updating the memory map comment in assembly stub I also added a pause instruction to the cpu spin lock as this was added to the C code in latest upstream rebase. Dump sympbols from smm.elf binary to see the new regions: 00010000 B _heap 00014000 B _eheap 00014000 T _smm_c_handler_start 0001b240 T _smm_c_handler_end Change-Id: I45f0ab4df1fdef3b626f877094a58587476ac634 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1308 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-04-04Add support to run SMM handler in TSEG instead of ASEGStefan Reinauer
Traditionally coreboot's SMM handler runs in ASEG (0xa0000), "behind" the graphics memory. This approach has two issues: - It limits the possible size of the SMM handler (and the number of CPUs supported in a system) - It's not considered a supported path anymore in newer CPUs.

2011-10-15SMM: Move wbinvd after pmode jumpStefan Reinauer
According to Rudolf Marek putting a memory instruction between the CR0 write and the jmp in protected mode switching might hang the machine. Move it after the jmp. There might be a better solution for this, such as enabling the cache, as keeping it disabled does not prevent cache poisoning attacks, so there is no real point. However, Intel docs say that SMM code in ASEG is always running uncached, so we might want to consider running SMM out of TSEG instead, as well.

2011-06-18SMM: flush caches after disabling cachingSven Schnelle
Fixes spurious SMI crashes i've seen, and ACPI/SMM interaction. For reference, the mail i've sent to ML with the bugreport: whenever i've docked/undocked the thinkpad from the docking station, i had to do that twice to get the action actually to happen. First i thought that would be some error in the ACPI code. Here's a short explanation how docking/undocking works: 1) ACPI EC Event 0x37 Handler is executed (EC sends event 0x37 on dock) 2) _Q37 does a Trap(SMI_DOCK_CONNECT). Trap is declared as follows: a) Store(Arg0, SMIF) // SMIF is in the GNVS Memory Range b) Store(0, 0x808) // Generates I/O Trap to SMM c) // SMM is executed d) Return (SMIF) // Return Result in SMIF I've verified that a) is really executed with ACPI debugging in the Linux Kernel. It writes the correct value to GNVS Memory. After that, i've logged the SMIF value in SMM, which contains some random (or former) value of SMIF. So i've added the GNVS area to /proc/mtrr which made things work. I've also tried a wbinvd() in SMM code, with the same result. After reading the src/cpu/x86/smm/smmhandler.S code, i've recognized that it starts with: movw $(smm_gdtptr16 - smm_handler_start + SMM_HANDLER_OFFSET), %bx data32 lgdt %cs:(%bx) movl %cr0, %eax andl $0x7FFAFFD1, %eax /* PG,AM,WP,NE,TS,EM,MP = 0 */ orl $0x60000001, %eax /* CD, NW, PE = 1 */ movl %eax, %cr0 /* Enable protected mode */ data32 ljmp $0x08, $1f ...which disables caching in SMM code, but doesn't flush the cache. So the problem is: - the linux axpi write to the SMIF GNVS Area will be written to Cache, because GNVS is WB - the SMM code runs with cache disabled, and fetches SMIF directly from Memory, which is some other value Possible Solutions: - enable cache in SMM (yeah, cache poisoning...) - flush caches in SMM (really expensive) - mark GNVS as UC in Memory Map (will only work if OS really marks that Area as UC. Checked various vendor BIOSes, none of them are marking NVS as UC. So this seems rather uncommon.) - flush only the cache line which contains GNVS. Would fix this particular problem, but users/developers could see other Bugs like this. And not everyone likes to debug such problems. So i won't like this solution.
