Change in coreboot[master]: [RFC]arch/x86: Only allow normal and fallback cbfs prefixes
by Arthur Heymans (Code Review) 21 Apr '22

21 Apr '22

Arthur Heymans has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/35823 ) Change subject: [RFC]arch/x86: Only allow normal and fallback cbfs prefixes ...................................................................... [RFC]arch/x86: Only allow normal and fallback cbfs prefixes Using other cbfsprefixes is errorprone: It requires a properly formatted cbfs file to be present (an error in the cbfsfile will render the system unbootable) and to correctly enter the cbfs prefix in menuconfig. Therefore remove this functionality that merely allows to use different names.

Change in ...coreboot[master]: [WIP]Makefile.inc: Add Macro to generate cbfs int files
by Arthur Heymans (Code Review) 21 Apr '22

21 Apr '22

Arthur Heymans has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/33353 Change subject: [WIP]Makefile.inc: Add Macro to generate cbfs int files ...................................................................... [WIP]Makefile.inc: Add Macro to generate cbfs int files Add the makefile function 'add-cbfs-int' to generate cbfs files containing a little endian integer. Adding cbfs files containing a 64 bit is usually done with cbfstool add-int, but this requires the coreboot.rom image to be already build which clutters the Makefile. Instead add a method to cleanly generate the cbfsfile containing a 64bit little endian int which integrates better with the rest of the makefile.

Change in coreboot[master]: cpu/x86/smm: Add sinkhole mitigation to relocatable smmstub
by Arthur Heymans (Code Review) 11 Apr '22

11 Apr '22

Arthur Heymans has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/37289 ) Change subject: cpu/x86/smm: Add sinkhole mitigation to relocatable smmstub ...................................................................... cpu/x86/smm: Add sinkhole mitigation to relocatable smmstub This adds a check for LAPIC base twice. One very early check when the CPU is still executing in real mode checks if the LAPIC base is inside the region [smmbase,smmbase + SMM_DEFAULT_SIZE). This cannot use anything but a hardcoded size since even accessing the relocatable parameters is impossible in the state of the CPU. The actual SMI handler is located above smmbase + SMM_DEFAULT_SIZE and before jumping to it the LAPIC base is checked against the whole SMM region. Given that we have a working stack at this point, this is done in C code. UNTESTED.

31 Mar '22

Erin Lo has uploaded this change for review.

Change in coreboot[master]: driver/thunderbolt: Driver for allocating hotplug resources
by Jeremy Soller (Code Review) 24 Mar '22

24 Mar '22

Jeremy Soller has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/35946 ) Change subject: driver/thunderbolt: Driver for allocating hotplug resources ...................................................................... driver/thunderbolt: Driver for allocating hotplug resources This adds a new driver which can be selected with DRIVERS_THUNDERBOLT that, by default, adds 32 PCI subordinate numbers, 256 MiB of both prefetchable and non-prefetchable memory, and 8 KiB of I/O space to matching devices. It currently supports the JHL7540 Thunderbolt 3 bridge, but other devices can be added easily. In order to support the allocation of hotplugged PCI buses, a new field was added to struct device called hotplug_buses. This is defaulted to zero, but when set, it adds the hotplug_buses value to the subordinate value of the PCI bridge. This allows devices to be plugged in and unplugged after boot. This code was tested on the System76 Darter Pro (darp6). Before this change, there are not enough resources allocated to the Thunderbolt PCI bridge to allow plugging in new devices after boot. This can be worked around in the Linux kernel by passing a boot param such as: pci=assign-buses,hpbussize=32,realloc This change makes it possible to use Thunderbolt hotplugging without kernel parameters, and attempts to match closely what our motherboard manufacturer's firmware does by default.
