powerpc/book3s64/pkeys: Remove is_pkey_enabled()
config:
Hi, all,
I have several ASMedia USB 3.x host controllers (ASM2142 and ASM3142,
both share the same Vendor ID/Device ID pair) that I'd like to use
with a POWER9 system (a Raptor Computing Systems Talos II).
Unfortunately, while the kernel recognizes the controllers just fine,
as soon as I plug in
Power10 has removed 512 bytes boundary from match criteria. i.e. The watch
range can cross 512 bytes boundary.

So far Book3S Powerpc supported only one watchpoint. Power10 is

As per the PAPR, bit 0 of byte 64 in pa-features property indicates
availability of 2nd DAWR registers. i.e. If this bit is set, 2nd
DAWR is present, otherwise not. Host generally uses "cpu-features",
which masks "pa-features". But "cpu-features" are still not used for
guests and thus this change

CPU_FTR_DAWR is by default enabled for host via CPU_FTRS_DT_CPU_BASE
(controlled by CONFIG_PPC_DT_CPU_FTRS). But cpu-features device-tree
node is not PAPR compatible and thus not yet used by kvm or pHyp
guests. Enable watchpoint functionality on power10 guest (both kvm

'ea' returned by analyse_instr() needs to be aligned down to cache
block size for CACHEOP instructions. analyse_instr() does not set
size for CACHEOP, thus size also needs to be calculated manually.
Fixes: 27985b2a640e ("powerpc/watchpoint: Don't ignore extraneous exceptions
blindly")
Fixes:
Pedro Miraglia Franco de Carvalho noticed that on p8/p9, DAR value is
inconsistent with different type of load/store. Like for byte,word
etc. load/stores, DAR is set to the address of the first byte of
overlap between watch range and real access. But for quadword load/
store it's sometime set to
Milton Miller reported that we are aligning start and end address to
wrong size SZ_512M. It should be SZ_512. Fix that.
While doing this change I also found a case where ALIGN() comparison
fails. Within a given aligned range, ALIGN() of two addresses does not
match when start address is pointing
Last series[1] was to add basic infrastructure support for more than
one watchpoint on Book3S powerpc. This series actually enables the 2nd
DAWR for baremetal and powervm. Kvm guest is still not supported.

Jarkko Sakkinen a écrit :
Rename module_alloc() to text_alloc() and module_memfree() to
text_memfree(), and move them to kernel/text.c, which is unconditionally
compiled to the kernel proper. This allows kprobes, ftrace and bpf to
allocate space for executable code without requiring to compile

This primitive has been renamed, but because it was spelled incorrectly in the
first place it must have escaped the fixup patch. As far as I can tell this
logic is still correct: smp_mb__after_spinlock() uses the default smp_mb()
