explicitly if they want to. However, since deprecation does not mean
removal, the same code is also still duplicated in platform_helpers.S.

The duplicated code contains both empty stubs for the !MULTI_CONSOLE_API

commit d35cc34 (Console: Use callee-saved registers) for

only keep the empty stubs (guarded by !ERROR_DEPRECATED), which should

"When Core 0 is on and Core 1 is in power-off state, a Core 1

plat/css: allow platforms to define the system power domain level

The CSS_SYSTEM_PWR_DMN_LVL macro that defines the system power domain
level is fixed at ARM_PWR_LVL2 for all CSS platforms. However, the
system power domain level can be different for CSS platforms that
use multi-threaded CPUs.

So, in preparation towards adding support for platforms that use
multi-threaded CPUs, refactor the definition of CSS_SYSTEM_PWR_DMN_LVL
such that CSS_SYSTEM_PWR_DMN_LVL is uniquely defined for each of the
CSS platform.

5 years agoInitial Spectre V1 mitigations (CVE-2017-5753).
Joel Hutton [Tue, 9 Oct 2018 13:08:42 +0000 (14:08 +0100)]
Initial Spectre V1 mitigations (CVE-2017-5753).

Initial Spectre Variant 1 mitigations (CVE-2017-5753).
A potential speculative data leak was found in PSCI code, this depends
on a non-robust implementation of the `plat_get_core_pos_by_mpidr()`
function. This is considered very low-risk. This patch adds a macro to
mitigate this. Note not all code paths could be analyzed with current
tools.

Add a macro which makes a variable 'speculation safe', using the
 __builtin_speculation_safe_value function of GCC and llvm. This will be
available in GCC 9, and is planned for llvm, but is not currently in
mainline GCC or llvm. In order to implement this mitigation the compiler
must support this builtin. Support is indicated by the
__HAVE_SPECULATION_SAFE_VALUE flag.

The -mtrack-speculation option maintains a 'tracker' register, which
determines if the processor is in false speculation at any point. This
adds instructions and increases code size, but avoids the performance
impact of a hard barrier.

Without the -mtrack-speculation option, __builtin_speculation_safe_value
expands to a

    ISB
    DSB SY

sequence after a conditional branch, before the
speculation safe variable is used. With -mtrack-speculation a

    CSEL tracker, tracker, XZR, [cond];
    AND safeval,tracker;
    CSDB

sequence is added instead, clearing the vulnerable variable by
AND'ing it with the tracker register, which is zero during speculative
execution. [cond] are the status flags which will only be true during
speculative execution. For more information on
__builtin_speculation_safe_value and the -mtrack-speculation option see
https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability/compiler-support-for-mitigations

The -mtracking option was not added, as the performance impact of the
mitigation is low, and there is only one occurence.
