Liang Yi 688a41c290 hv: mod: do not use explicit arch name when including headers
Instead of "#include <x86/foo.h>", use "#include <asm/foo.h>".

In other words, we are adopting the same practice in Linux kernel.

Liang Yi 33ef656462 hv/mod-irq: use arch specific header files
Requires explicit arch path name in the include directive.

The config scripts was also updated to reflect this change.

Shiqing Gao 6f10bd00bf hv: coding style clean-up related to Boolean
While following two styles are both correct, the 2nd one is simpler.
	bool is_level_triggered;
	1. if (is_level_triggered == true) {...}
	2. if (is_level_triggered) {...}

This patch cleans up the style in hypervisor.

dongshen a425730f64 acrn-config: rename MAX_PLATFORM_CLOS_NUM to HV_SUPPORTED_MAX_CLOS
HV_SUPPORTED_MAX_CLOS:
 This value represents the maximum CLOS that is allowed by ACRN hypervisor.
 This value is set to be least common Max CLOS (CPUID.(EAX=0x10,ECX=ResID):EDX[15:0])
 among all supported RDT resources in the platform. In other words, it is
 min(maximum CLOS of L2, L3 and MBA). This is done in order to have consistent
 CLOS allocations between all the RDT resources.

Yan, Like 869ccb7ba8 HV: RDT: add CDP support in ACRN
CDP is an extension of CAT. It enables isolation and separate prioritization of
code and data fetches to the L2 or L3 cache in a software configurable manner,
depending on hardware support.

This commit adds a Kconfig switch "CDP_ENABLED" which depends on "RDT_ENABLED".
CDP will be enabled if the capability available and "CDP_ENABLED" is selected.

Yan, Like 277c668b04 HV: RDT: clean up RDT code
This commit makes some RDT code cleanup, mainling including:
- remove the clos_mask and mba_delay validation check in setup_res_clos_msr(), the check will be done in pre-build;
- rename platform_clos_num to valid_clos_num, which is set as the minimal clos_mas of all enabled RDT resouces;
- init the platform_clos_array in the res_cap_info[] definition;
- remove the unnecessary return values and return value check.

Yan, Like f774ee1fba HV: RDT: merge struct rdt_cache and rdt_membw in to a union
A RDT resource could be CAT or MBA, so only one of struct rdt_cache and struct rdt_membw
would be used at a time. They should be a union.
This commit merge struct rdt_cache and struct rdt_membw in to a union res.

Vijay Dhanraj eaad91fd71 HV: Remove RDT code if CONFIG_RDT_ENABLED flag
is not set

This patch does the following,
1. Removes RDT code if CONFIG_RDT_ENABLED flag is
not set.
2. Set the CONFIG_RDT_ENABLED flag only on platforms
that support RDT so that build scripts will automatically
reflect the config.

Vijay Dhanraj d0665fe220 HV: Generalize RDT infrastructure and fix RDT
cache configuration.

This patch creates a generic infrastructure for
RDT resources instead of just L2 or L3 cache. This
patch also fixes L3 CAT config overwrite by L2 in
cases where both L2 and L3 CAT are supported.

Vijay Dhanraj 887e3813bc HV: Add both HW and SW checks for RDT support
There can be times when user unknowinlgy enables
CONFIG_CAT_ENBALED SW flag, but the hardware might
not support L3 or L2 CAT. In such case software can
end up writing to the CAT MSRs which can cause
undefined results. The patch fixes the issue by
enabling CAT only when both HW as well software
via the CONFIG_CAT_ENABLED supports CAT.

The patch also address typo with "clos2prq_msr"
function name. It should be "clos2pqr_msr" instead.
PQR stands for platform qos register.

Vijay Dhanraj b8a021d658 HV: split L2 and L3 cache resource MSR
Upcoming intel platforms can support both L2 and L3
but our current code only supports either L2 or L3 CAT.
So split the MSRs so that we can support allocation
for both L2 and L3.

This patch does the following,
1. splits programming of L2 and L3 cache resource
based on the resource ID.
2. Replace generic platform_clos_array struct with resource
specific struct in all the existing board.c files.
