* badram: Make DEFAULT_MASK depend on ARCH_BITS, not x86_64 architecture.
* badram: Don't display leading zeros for BadRAM addresses.
* badram: Merge patterns immediately when there is no additional cost.
The current algorithm only starts merging patterns when num_patterns
equals MAX_PATTERNS, which can lead to having several patterns that
could have been merged into one at no additional cost. e.g.
patterns = [
(0x00, 0xfffffffffffffff8),
(0x08, 0xfffffffffffffff8)
]
can appear, even though
patterns = [
(0x00, 0xfffffffffffffff0)
]
represents the exact same addresses at the same cost.
So, at the same time as we test whether an address is already covered,
also check if we can cheaply combine the new address with an existing
pattern.
* badram: Factor out code that wraps to a new line when necessary.
In preparation for next commit.
* badram: Add more modes for recording/displaying error maps.
The original code just supported recording and displaying patterns suitable
for use with the Linux BadRAM extension or GRUB badram command. With some
minor changes it can be made to record address ranges and display them
either in the format used by the Linux memmap boot command line option
or as a simple list of memory page numbers (which can be used with the
Windows bcdedit program).
* badram: Increase the number of stored patterns/ranges.
* Update README to include the new error reporting modes.
* Add a file containing useful macro definitions, currently a single top-level macro for obtaining the size of an array; use it to replace a sizeof(x) / sizeof(x[0]) construct in system/smbus.c . This requires switching the GCC build mode from C11 to C11 with GCC extensions.
* Initial NUMA awareness (#12) support: parse the ACPI SRAT to build up new internal structures related to proximity domains and affinity; use these structures in setup_vm_map() and calculate_chunk() to skip the work on the processors which don't belong to the proximity domain currently being tested.
Tested on a number of 1S single-domain, 2S multi-domain and 4S multi-domain platforms.
SKIP_RANGE(iterations) trick by Martin Whitaker.
* Initial commit for ECC support. Preliminary support for AMD Zen.
* Clear ECC registers at startup
* Add config flag (enable_ecc_polling) to toggle ECC polling. (Currently disabled by default for v7 release)
Also, remove the no_temperature var to keep only the enable_temperature flag
Older Atom still have the enable_temperature flag hard-coded to false until further tests are done
Read the memory controller configuration (instead of just relying on SPD data) to get the actual live settings.
Currently supported platforms:
* Intel SNB to RPL (Core 2nd Gen to Core 13th Gen) - Desktop only (no Server nor Mobile)
* AMD SMR to RPL (Zen to Zen4) - Desktop only (no Server, Mobile nor APU).
Individual commits below for archival:
* First functions skeleton for reading IMC/ECC Registers
* Change directory name from 'chipsets' to 'mch' (Memory Controller Hub)
* Add Intel HSW and fix new files encoding
* First Intel HSW IMC implementation
* Add an option to disable MCH registers polling
* Remove old include from Makefiles
* Better Makefile and padding fixes
* Statically init 'imc' struct to generate string relocation record
* Small typos & code fixes
* Add IMC support for Intel Core 6/7/8/9th Gen (SKL/KBL/CFL/CML) This is a bit more complex than Haswell and below because MMIO switched to 64-bit with Skylake (lot of) betatesting needed
* Add IMC read support for Intel SNB/IVB (2nd/3rd gen Core)
* Fix hard-lock on Intel SNB/IVB due to wrong access type on MCHBAR pointer
* Move AMD SMN Registers & offsets to a specific header file
* Add IMC Read support for AMD Zen/Zen2 CPUs
* Change 'IMC' to 'MCH' in Makefiles to match actual mch/ directory
* Add IMC Reading support for Intel ADL&RPL CPUs (Core Gen12&13)
* Add support for Intel Rocket Lake (Core 11th Gen) and AMD Vermeer
* Add IMC reading for AMD Zen4 'Raphael' AM5 CPUs
* Various Cleanup #1
Change terminology from Intel-based 'MCH' (Memory Controller Hub) to more universal 'IMC' (Integrated Memory Controller) Integrate imc_type var into imc struct. Remove previously created AMD SNM header file
* Various Cleanup 2
* Change DDR5 display format for IMC specs
DDR5 Freq can be > 10000 and timings up to 63-127-127-127, which overwflow the available space.
This commit remove the raw frequency on DDR5 (which may be incorrect due to Gear mechanism) and leave a bit of space to display the Gear engaged in the future
By default, don't re-display FAIL banner after it has been discarded (#130 & #173)
Add an option to re-display FAIL banner even if previously discarded
Most legacy BIOSs will support USB legacy keyboard emulation. Using that
will avoid having to reserve memory for the USB drivers, and should
improve the chance of having a working keyboard without having to work
around various USB device quirks.
* Add new heap manager.
* Convert OHCI driver to use new heap manager.
* Convert UHCI driver to use new heap manager.
* Convert EHCI driver to use new heap manager.
* Convert XHCI driver to use new heap manager.
* Convert SMP to use new heap manager.
* Add a "usbinit" boot option to handle various buggy USB devices.
This replaces the "keyboard=buggy-usb" option, and adds a second
workaround to handle the problem seen in issue #107.
Add AP Enumeration to distinguish E-Core from P-Core on Intel Hybrid CPUs, and exclude them from the selected cores by default. Including E-Cores slows down some tests and takes longer to catch memory errors.
A new exclude_ecores flag has been added in config.c to include E-Cores if needed.
When USB keyboard detection is enabled, physical memory pages are reserved
for use by the USB drivers. The physical memory map exposed by pmem.h does
not indicate where the ACPI tables reside, so we may end up using pages
that contain ACPI tables (or for that matter, the boot parameters and boot
command line). So rather than introduce a more complicated memory allocation
scheme, make sure we have finished with all the data passed to us by the
BIOS and/or boot loader before we start probing for USB devices.
The only downside to this is that it is no longer possible to interactively
disable parsing of the ACPI tables - that can now only be done by using the
"nosmp" boot option.
If the usbdebug option is present, pause at the end of the USB scan until
a key is pressed. Otherwise, if the keyboard=usb option is present and no
USB keyboards were discovered, pause for 10 seconds. Otherwise don't pause.
* Add preliminary support for TTY Serial/UART (#15)
* Use shadow_buffer instead of VGA buffer to get a framebuffer-agnostic TTY supprot
* Added menu browsing & inputs from Serial TTY (#15)
* Add fix for degree symbol on TTY. Correct serial.c & serial.h file created with CRLF (#15)
* Move tty_error_redraw() to insure correct redraw when a error occurs
* Many reindent / cleanup
* Various optimization from @martinwhitaker comments
The old barrier implementation was very slow when running on a multi-socket
machine (pcmemtest issue 16).
The new implementation provides two options:
- when blocked, spin on a thread-local flag
- when blocked, execute a HLT instruction and wait for a NMI
The first option might be faster, but we need to measure it to find out. A
new boot command line option is provided to select between the two, with a
third setting that uses a mixture of the two.
