Daniel Leung cbb252adef boards: x86: update build_grub.sh for Python 3
Since Python 2 is already EOL, Linux distributions are starting
to drop support for Python 2. For example, on Ubuntu 20.04,
"python" is no longer available. This breaks the bootstrap
and autogen.sh as they are both default to executing "python".
Fix this by setting the PYTHON environment variable before
building so both scripts will use python3 instead.

Also update git checkout to grab the official 2.04 release.

Fixes #25398

Zide Chen f32eeba925 dts: x86: configure different IO APIC delivery modes for various devices
For HPET devices, configure it with fixed delivery mode because HPET
timer interrupt is needed to fuel the scheduler for all CPUS.

For all other type of devices, like UART, I2C, GPIO, Ethernet, etc.
configure them as lowest priority delivery mode, in which IO APIC
delivers the interrupt to the processor core that is executing at the
lowest priority among all the processors listed in the specified
destination. In this case, the device drivers can avoid the trouble of
handling repeated interrupts delivered to all CPUS.

Ulf Magnusson a42a42cd5a kconfig: Replace defconfig singe-symbol 'if's with 'depends on'
Same deal as in commit eddd98f ("kconfig: Replace some single-symbol
'if's with 'depends on'"), for all symbols defined within defconfig
files. See that commit for an explanation.

Maybe 'if's were used originally to mirror the 'if's in the main Kconfig
files, and then it got copied around by people assuming 'if' must work
differently from 'depends on'. It doesn't match in every spot at least.
Better to keep it simple and just consistently use 'depends on' when
it's a single symbol/choice I think. Helps reinforce that 'if' isn't
magic too.

Verified by printing all Kconfig menu nodes (symbols, choices, menus,
etc.) before and after the change and diffing (should show no
difference).

Ulf Magnusson c5839f834b kconfig: Remove assignments to CONFIG_<arch> syms and hide them
All board defconfig files currently set the architecture in addition to
the board and the SoC, by setting e.g. CONFIG_ARM=y. This spams up
defconfig files.

CONFIG_<arch> symbols currently being set in configuration files also
means that they are configurable (can be changed in menuconfig and in
configuration files), even though changing the architecture won't work,
since other things get set from -DBOARD=<board>. Many boards also allow
changing the architecture symbols independently from the SoC symbols,
which doesn't make sense.

Get rid of all assignments to CONFIG_<arch> symbols and clean up the
relationships between symbols and the configuration interface, like
this:

1. Remove the choice with the CONFIG_<arch> symbols in arch/Kconfig and
   turn the CONFIG_<arch> symbols into invisible
   (promptless/nonconfigurable) symbols instead.

   Getting rid of the choice allows the symbols to be 'select'ed (choice
   symbols don't support 'select').

2. Select the right CONFIG_<arch> symbol from the SOC_SERIES_* symbols.
   This makes sense since you know the architecture if you know the SoC.

   Put the select on the SOC_* symbol instead for boards that don't have
   a SOC_SERIES_*.

3. Remove all assignments to CONFIG_<arch> symbols. The assignments
   would generate errors now, since the symbols are promptless.

The change was done by grepping for assignments to CONFIG_<arch>
symbols, finding the SOC_SERIES_* (or SOC_*) symbol being set in the
same defconfig file, and putting a 'select' on it instead.

See
https://github.com/ulfalizer/zephyr/commits/hide-arch-syms-unsquashed
for a split-up version of this commit, which will make it easier to see
how stuff was done. This needs to go in as one commit though.

This change is safer than it might seem re. outstanding PRs, because any
assignment to CONFIG_<arch> symbols generates an error now, making
outdated stuff easy to catch.

Andrew Boie e34f1cee06 x86: implement kernel page table isolation
Implement a set of per-cpu trampoline stacks which all
interrupts and exceptions will initially land on, and also
as an intermediate stack for privilege changes as we need
some stack space to swap page tables.

Set up the special trampoline page which contains all the
trampoline stacks, TSS, and GDT. This page needs to be
present in the user page tables or interrupts don't work.

CPU exceptions, with KPTI turned on, are treated as interrupts
and not traps so that we have IRQs locked on exception entry.

Add some additional macros for defining IDT entries.

Add special handling of locore text/rodata sections when
creating user mode page tables on x86-64.

Assignments to promptless symbols have no effect. Flagged by
https://github.com/zephyrproject-rtos/zephyr/pull/20742.

From looking at
http://www.mouser.com
  /catalog/specsheets/CircuitCO_595-MINNOWMAX-DUAL%20Data%20Sheet.pdf
, this board uses an Intel Atom E3815 or an Intel Atom E3825 CPU.

Both of those CPUs are listed as vulnerable to all three variants of
Meltdown and Spectre in
https://www.techarp.com/guides/complete-meltdown-spectre-cpu-list/6/.

All the X86_NO_SPECTRE_V* symbols default to n (and it seems nothing
turns them on at the moment), so just remove the assignment, which will
be a no-op.

Also remove the comment re. Spectre V4, as it seems this board is
vulnerable to more than that, though I could've missed something.
