2021-09-03arch/x86: Skip returning default leaf value as `0`Subrata Banik
`cpu_get_cache_info_leaf()` function is responsible to report leaf value for CPU that have support for deterministic cache cpuid.

In x86_64, the first function parameter is passed in rdi register, and the 32-bit code after exiting long mode reads the resume vector in 4(%esp), so it's needed to save the resume vector from rdi to 4(%rsp). Also note that the function attribute "regparm" only works on x86-32 targets according to the GCC manual, so "asmlinkage" doesn't change the ABI of an x86_64 function. Tested on HP EliteBook 2560p.

2021-06-15treewide: Disable R_AMD64_32S relocation supportPatrick Rudolph
This fixes a hard to debug hang that could occur in any stage, but in the end it follows simple rules and is easy to fix. In long mode the 32bit displacement addressing used on 'mov' and 'lea' instructions is sign-extended. Those instructions can be found using readelf on the stage and searching for relocation type R_X86_64_32S. The sign extension is no issue when either running in protected mode or the code module and thus the address is below 2GiB. If the address is greater than 2GiB, as usually the case for code in TSEG, the higher address bits [64:32] are all set to 1 and the effective address is pointing to memory not paged. Accessing this memory will cause a page fault, which isn't handled either. To prevent such problems - disable R_AMD64_32S relocations in rmodtool - add comment explaining why it's not allowed - use the pseudo op movabs, which doesn't use 32bit displacement addressing - Print a useful error message if such a reloc is present in the code Fixes a crash in TSEG and when in long mode seen on Intel Sandybridge.

2021-05-14cbfs: Increase mcache size defaultsJulius Werner
The CBFS mcache size default was eyeballed to what should be "hopefully enough" for most users, but some recent Chrome OS devices have already hit the limit. Since most current (and probably all future) x86 chipsets likely have the CAR space to spare, let's just double the size default for all supporting chipsets right now so that we hopefully won't run into these issues again any time soon. The CBFS_MCACHE_RW_PERCENTAGE default for CHROMEOS was set to 25 under the assumption that Chrome OS images have historically always had a lot more files in their RO CBFS than the RW (because l10n assets were only in RO). Unfortunately, this has recently changed with the introduction of updateable assets. While hopefully not that many boards will need these, the whole idea is that you won't know whether you need them yet at the time the RO image is frozen, and mcache layout parameters cannot be changed in an RW update. So better to use the normal 50/50 split on Chrome OS devices going forward so we are prepared for the eventuality of needing RW assets again. The RW percentage should really also be menuconfig-controllable, because this is something the user may want to change on the fly depending on their payload requirements. Move the option to the vboot Kconfigs because it also kinda belongs there anyway and this makes it fit in better in menuconfig. (I haven't made the mcache size menuconfig-controllable because if anyone needs to increase this, they can just override the default in the chipset Kconfig for everyone using that chipset, under the assumption that all boards of that chipset have the same amount of available CAR space and there's no reason not to use up the available space. This seems more in line with how this would work on non-x86 platforms that define this directly in their memlayout.ld.) Also add explicit warnings to both options that they mustn't be changed in an RW update to an older RO image.

2021-03-16cbfs: Remove prog_locate() for stages and rmodulesJulius Werner
This patch removes the prog_locate() step for stages and rmodules. Instead, the stage and rmodule loading functions will now perform the locate step directly together with the actual loading. The long-term goal of this is to eliminate prog_locate() (and the rdev member in struct prog that it fills) completely in order to make CBFS verification code safer and its security guarantees easier to follow. prog_locate() is the main remaining use case where a raw rdev of CBFS file data "leaks" out of cbfs.c into other code, and that other code needs to manually make sure that the contents of the rdev get verified during loading. By eliminating this step and moving all code that directly deals with file data into cbfs.c, we can concentrate the code that needs to worry about file data hashing (and needs access to cbfs_private.h APIs) into one file, making it easier to keep track of and reason about. This patch is the first step of this move, later patches will do the same for SELFs and other program types.

2021-01-07arch/x86: Move prologue to .init sectionKyösti Mälkki
For arch/x86 the realmode part has to be located within the same 64 KiB as the reset vector. Some older intel platforms also require 4 KiB alignment for _start16bit. To enforce the above, and to separate required parts of .text without matching *(.text.*) rules in linker scripts, tag the pre-C environment assembly code with section .init directive. Description of .init section for ELF: This section holds executable instructions that contribute to the process initialization code. When a program starts to run, the system arranges to execute the code in this section before calling the main program entry point (called main for C programs).
