Hi,
When developing PVH for OVMF, I've used the lapic timer. It turns out that the
way it is used by OVMF did not work with Xen [1]. I tried to find out how

the behavior of the vlapic timer.

If we take TSC-deadline mode timer out of the picture, the Intel SDM

After this patch, the timer is no longer disarmed on change of mode, so

We have limited number (slightly under NR_DYNAMIC_VECTORS=192) of IRQ
vectors that are available to each processor. Currently, when x2apic
cluster mode is used (which is default), each vector is shared among
all processors in the cluster. With many IRQs (as is the case on systems

Hi Bhupinder,
I gave another and I have a couple of comments.
Booting Linux with earlycon enabled take quite a while. I can see the
characters coming slower than on the minitel. It seems to be a bit
better after switching off the bootconsole. Overall Linux is taking ~20
times to boot with pl0

Hello all,
This is third version. Instead of 4 patches, there are 7 now.
As part of the series, I make some functions in traps.c
available globally, moved SMC conditional check into
separate patch, changed how PSCI functiond numbers are defined.
Per-patch changes are described in corresponding pa
SMCCC (SMC Call Convention) describes how to handle both HVCs and SMCs.
SMCCC states that both HVC and SMC are valid conduits to call to a different
firmware functions. Thus, for example PSCI calls can be made both by
SMC or HVC. Also SMCCC defines function number coding for such calls.
Besides fun
From: Volodymyr Babchuk
The following list of functions:
- advance_pc()
- check_conditional_instr()
- inject_undef_exception()
- inject_iabt_exception()
- inject_dabt_exception()
- inject_vabt_exception()
are now globaly visible. This change is needed becase we plan to handle SMCs
in diff
vsmc.h provides definitions to construct SMC call function number according
to SMCCC. We don't need multiple definitions for one thing, and definitions
in vsmc.h are more generic than ones used in psci.h.
So psci.h will only provide function codes and whole SMC function number
will be constructed
On certain ARM arhcitectures SMC instruction can be conditional
(ARM DDI 0487A.k page D7-1949) and we need to check if that
conditional was meet.

PSCI is part of HVC/SMC interface, so it should be handled in
appropriate place: `vsmc.c`. This patch just moves PSCI
handler calls from `traps.c` to `vsmc.c`.
PSCI is considered as two different "services" in terms of SMCCC.
Older PSCI 1.0 is treated as "architecture service", while never
PSCI 2.
From: Volodymyr Babchuk
There are standard functions set_user_reg() and get_user_reg(). We can
use them in PSCI_SET_RESULT()/PSCI_ARG() macroses instead of relying on
CONFIG_ARM_64 definition.

PSCI handling code had helper routine that checked calling convention.
It does not needed anymore, because:
- Generic handler checks that 64 bit calls can be made only by
64 bit guests.
- SMCCC requires that 64-bit handler should support both 32 and 64 bit
calls even if they originate fro
