2021-10-05arch/x86,cpu/x86: Introduce new method for accessing cpu_infoRaul E Rangel
There is currently a fundamental flaw in the current cpu_info() implementation. It assumes that current stack is CONFIG_STACK_SIZE aligned. This assumption breaks down when performing SMM relocation. The first step in performing SMM relocation is changing the SMBASE. This is accomplished by installing the smmstub at 0x00038000, which is the default SMM entry point. The stub is configured to set up a new stack with the size of 1 KiB (CONFIG_SMM_STUB_STACK_SIZE), and an entry point of smm_do_relocation located in RAMSTAGE RAM. This means that when smm_do_relocation is executed, it is running in SMM with a different sized stack. When cpu_info() gets called it will be using CONFIG_STACK_SIZE to calculate the location of the cpu_info struct. This results in reading random memory. Since cpu_info() has to run in multiple environments, we can't use a compile time constant to locate the cpu_info struct. This CL introduces a new way of locating cpu_info. It uses a per-cpu segment descriptor that points to a per-cpu segment that is allocated on the stack. By using a segment descriptor to point to the per-cpu data, we no longer need to calculate the location of the cpu_info struct. This has the following advantages: * Stacks no longer need to be CONFIG_STACK_SIZE aligned. * Accessing an unconfigured segment will result in an exception. This ensures no one can call cpu_info() from an unsupported environment. * Segment selectors are cleared when entering SMM and restored when leaving SMM. * There is a 1:1 mapping between cpu and cpu_info. When using COOP_MULTITASKING, a new cpu_info is currently allocated at the top of each thread's stack. This no longer needs to happen. This CL guards most of the code with CONFIG(CPU_INFO_V2). I did this so reviewers can feel more comfortable knowing most of the CL is a no-op. I would eventually like to remove most of the guards though. This CL does not touch the LEGACY_SMP_INIT code path. I don't have any way of testing it. The %gs segment was chosen over the %fs segment because it's what the linux kernel uses for per-cpu data in x86_64 mode. BUG=b:194391185, b:179699789 TEST=Boot guybrush with CPU_INFO_V2 and verify BSP and APs have correct %gs segment. Verify cpu_info looks sane. Verify booting to the OS works correctly with COOP_MULTITASKING enabled.

2021-09-29google/trogdor: Always initialize eDP bridge I2C QUP firmwareJulius Werner
In CB:52662 when MIPI display support was added, we accidentally changed the code flow for eDP displays such that i2c_init() will no longer be called when display_init_required() is false. This is a problem because on this platform, i2c_init() does not just prepare the I2C controller for firmware use, it also loads firmware to the controller that makes it behave like an I2C device in the first place -- a step that the kernel cannot later do on its own if the firmware didn't already do it. Skipping this initialization means the I2C controller becomes unusable to the kernel. This patch fixes the issue by making the i2c_init() unconditional again.
