ARM: proc: add definition of cpu_reset for ARMv6 and ARMv7 cores · f4daf06f

Will Deacon authored Jun 06, 2011



This patch adds simple definitions of cpu_reset for ARMv6 and ARMv7
cores, which disable the MMU via the SCTLR.

ARM: perf: add PMUv2 common event definitions · 6d4eaf99

Will Deacon authored Jan 19, 2011



The PMUv2 specification reserves a number of event encodings
for common events.

This patch adds these events to the common event enumeration
in preparation for PMUv2 cores, such as Cortex-A15.

ARM: perf: remove confusing comment from v7 perf events backend · 7b35fa47

Will Deacon authored Jun 03, 2011



The comment about measuring TLB misses and refills in the ARMv7 perf
backend makes little sense and refers loosely to raw counters that
should be used instead.

This patch removes the comments to avoid any confusion.

ARM: proc: add proc info for Cortex-A15MP using classic page tables · 7665d9d2

Will Deacon authored Jan 12, 2011



Multicore implementations of the Cortex-A15 require bit 6 of the
auxiliary control register to be set in order for cache and TLB
maintenance operations to be broadcast between CPUs.

This patch adds a new proc_info structure for Cortex-A15, which enables
the SMP bit during setup and includes the new HWCAP for integer
division.

ARM: proc: convert v7 proc infos into a common macro · dc939cd8

As most of the proc info content is common across all v7
processors, this patch converts existing A9 and generic v7
descriptions into a macro (allowing extra flags in future).

ARM: vfp: add VFPv4 capability detection and populate elf_hwcap · 18b9dc13

Will Deacon authored Jun 08, 2011



The presence of VFPv4 cannot be detected simply by looking at the FPSID
subarchitecture field, as a value >= 2 signifies the architecture as
VFPv3 or later.

This patch reads from MVFR1 to check whether or not the fused multiply
accumulate instructions are supported. Since these are introduced with
VFPv4, this tells us what we need to know.

ARM: hwcaps: add new HWCAP defines for ARMv7-A · 254cdf8e

Will Deacon authored Jun 03, 2011



Modern ARMv7-A cores can optionally implement these new hardware
features:

- VFPv4:
    The latest version of the ARMv7 vector floating-point extensions,
    including hardware support for fused multiple accumulate. D16 or D32
    variants may be implemented.

- Integer divide:
    The SDIV and UDIV instructions provide signed and unsigned integer
    division in hardware. When implemented, these instructions may be
    available in either both Thumb and ARM, or Thumb only.

This patch adds new HWCAP defines to describe these new features. The
integer divide capabilities are split into two bits for ARM and Thumb
respectively. Whilst HWCAP_IDIVA should never be set if HWCAP_IDIVT is
clear, separating the bits makes it easier to interpret from userspace.

ARM: hwcaps: use shifts instead of hardcoded constants · 194a7f72

Will Deacon authored Jun 03, 2011



The HWCAP numbers are defined as constants, each one being a power of 2.
This has become slightly unwieldy now that we have reached 32k.

This patch changes the HWCAP defines to use (1 << n) instead of coding
the constant directly. The values remain unchanged.

Without this patch, xscale_80200_A0_A1 is missing the
icache_flush_all entry, which would result in the wrong functions
