Maybe it could be used as a module probed dynamically or so,
Currently seems there is not need to make it selectable for users.

If the module is moved to drivers/soc/fsl, fsl_85xx_cache_ctlr.h in
arch/powerpc/sysdev is not available anymore to include directly.
Is it OK to just use a extern within fsl_85xx_sram_uapi.c,
(Seems it is not prefered to user extern in c files, but I can find
any documentation in Kernel.)
Or just add a header file fsl_85xx_sram.h containing only followings:
/* SPDX-License-Identifier: GPL-2.0 */
#ifndef __FSL_85XX_SRAM_H__
#define __FSL_85XX_SRAM_H__
extern struct mpc85xx_cache_sram *cache_sram;
static inline struct mpc85xx_cache_sram *mpc85xx_get_cache_sram(void)
{
return cache_sram;
}

After this change, the comment above is stale. the "holes in boot-time
mem_map" are handled by the caller now AFAIKs.

And then in patch 4, I'm not sure it is worth to keep SRAM_DYNAMIC as

This will work only if is defined all the time in the .h regardless of
CONFIG_FSL_85XX_SRAM_UAPI. Otherwise you should have something like that
in the .h, that you call all the time from the .c:
#ifdef CONFIG_FSL_85XX_SRAM_UAPI
static inline void set_cache_sram_dev(struct mpc85xx_cache_sram *sram,
struct device *dev)
{
sram->dev = dev;
}
#else
static inline void set_cache_sram_dev(struct mpc85xx_cache_sram *sram,
struct device *dev) { }
#endif

* [RFC PATCH v2 7/7] powerpc/selftest: reuse ppc-opcode macros to avoid redundancy
From: Balamuruhan S @ 2020-04-24 7:08 UTC (permalink / raw)
To: mpe
Cc: ravi.bangoria, jniethe5, Balamuruhan S, paulus, sandipan,
naveen.n.rao, linuxppc-dev
In-Reply-To: <20200424070853.443969-1-bala24@linux.ibm.com>
Avoid redefining macros to encode ppc instructions instead reuse it from
ppc-opcode.h, Makefile changes are necessary to compile memcmp_64.S with
__ASSEMBLY__ defined from selftests.

* [RFC PATCH v2 6/7] powerpc/ppc-opcode: fold PPC_INST_* macros into PPC_RAW_* macros
From: Balamuruhan S @ 2020-04-24 7:08 UTC (permalink / raw)
To: mpe
Cc: ravi.bangoria, jniethe5, Balamuruhan S, paulus, sandipan,
naveen.n.rao, linuxppc-dev
In-Reply-To: <20200424070853.443969-1-bala24@linux.ibm.com>
Lot of PPC_INST_* macros are used only ever in PPC_* macros, fold those
PPC_INST_* into PPC_RAW_* to avoid using PPC_INST_* accidentally.

* [RFC PATCH v2 4/7] powerpc/ppc-opcode: consolidate powerpc instructions from bpf_jit.h
From: Balamuruhan S @ 2020-04-24 7:08 UTC (permalink / raw)
To: mpe
Cc: ravi.bangoria, jniethe5, Balamuruhan S, paulus, sandipan,
naveen.n.rao, linuxppc-dev
In-Reply-To: <20200424070853.443969-1-bala24@linux.ibm.com>
move macro definitions of powerpc instructions from bpf_jit.h to ppc-opcode.h
and adopt the users of the macros accordingly. `PPC_MR()` is defined twice in
bpf_jit.h, remove the duplicate one.

* [RFC PATCH v2 0/7] consolidate PowerPC instruction encoding macros
From: Balamuruhan S @ 2020-04-24 7:08 UTC (permalink / raw)
To: mpe
Cc: ravi.bangoria, jniethe5, Balamuruhan S, paulus, sandipan,
naveen.n.rao, linuxppc-dev
ppc-opcode.h have base instruction encoding wrapped with stringify_in_c()
for raw encoding to have compatibility. But there are redundant macros for
base instruction encodings in bpf, instruction emulation test infrastructure
and powerpc selftests.
Currently PPC_INST_* macros are used for encoding instruction opcode and PPC_*
for raw instuction encoding, this rfc patchset introduces PPC_RAW_* macros for
base instruction encoding and reuse it from elsewhere. With this change we can
avoid redundant macro definitions in multiple files and start adding new
instructions in ppc-opcode.h in future.
Changes in v2:
-------------
Fix review comments/suggestions from Naveen and Michael Ellerman,
* Rename PPC_ENCODE_* to PPC_RAW_* for base instruction encoding macros.
* Split the patches that does mass renaming and make them simpler that just
adds new macros.
* Keep the patch to update all the existing names later (patch 6).
* Lot of PPC_INST_* macros are used only in ppc-opcode.h for PPC_* macros,
fold PPC_INST_* encoding into PPC_RAW_* to avoid using them accidentally.
* Fixed clipped macros that was due to a typo/copy-paste
* Consolidated all the instruction encoding macros from bpf_jit.h to
ppc-opcode.h
* squashed patch that removes the duplicate macro PPC_MR() in bpf_jit.h
* merge few changes in bpf_jit files from patch 2 into patch 3
* few fixes in powerpc selftest stringloops Makefile
* build tested for ppc64le_defconfig, ppc64e_defconfig and pmac32_defconfig
* Rebased on next branch of linuxppc tree
Testing:
-------
* Tested it by compiling vmlinux and comparing objdump of it with and without
the patchset and observed that it remains same,
# diff vmlinux_objdump vmlinux_rfc_objdump
2c2
< vmlinux: file format elf64-powerpcle
---
> vmlinux_rfc: file format elf64-powerpcle
* Tested building it with this changes for Fedora30 config, booted VM
with powerpc next and powerpc next + patchset to run powerpc selftest and
ftrace selftest. There were couple of failures that were common and
patchset did not introduce any new failures.
ftrace selftest:
---------------
# # of passed: 96
# # of failed: 1
# # of unresolved: 7
# # of untested: 0
# # of unsupported: 1
# # of xfailed: 1
# # of undefined(test bug): 0
not ok 1 selftests: ftrace: ftracetest # exit=1
powerpc selftest:
----------------
not ok 7 selftests: powerpc/dscr: dscr_sysfs_thread_test # exit=1
not ok 20 selftests: powerpc/pmu/ebb: lost_exception_test # TIMEOUT
not ok 2 selftests: powerpc/security: spectre_v2 # exit=1
Thanks to Naveen, Sandipan and Michael on overall suggestions/improvements.
I would request for review and suggestions to make it better.

Truely the module like this is the top level selection, and SRAM_DYNAMIC
should be selected by any caller modules. As SRAM_DYNAMIC may be used by
other drivers(in the future, but currently only us here), I think make it
seleted by this is better? (show below)

Remove tasklet for it may cause the reset operation
can't be handled immediately, then there will be
endless xrun interrupt.

Reducing the scope of local variables increases readability, you don't
have to scroll all up to the top of the function to see the declaration
of the variable.
common practice ? Are you sure ? Just have a look at fs/io_uring.c or
many other files in the kernel to see how uncommon your practice is.

We shouldn't add more stuff in arch/powerpc/sysdev/
Either it is dedicated to 85xx, and it should go into
arch/powerpc/platform/85xx/ , or it is common to several
platforms/architectures and should be moved to drivers/soc/fsl/

This function is not worth the mess of an #ifdef in a .c file.
cache_sram is already globaly visible, so this function should go in

* [PATCH v3 3/3] powerpc/eeh: Release EEH device state synchronously
From: Sam Bobroff @ 2020-04-24 4:58 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Nathan Lynch, Oliver O'Halloran
In-Reply-To: <cover.1587704308.git.sbobroff@linux.ibm.com>
EEH device state is currently removed (by eeh_remove_device()) during
the device release handler, which is invoked as the device's reference
count drops to zero. This may take some time, or forever, as other
threads may hold references.
However, the PCI device state is released synchronously by
pci_stop_and_remove_bus_device(). This mismatch causes problems, for
example the device may be re-discovered as a new device before the
release handler has been called, leaving the PCI and EEH state
mismatched.
So instead, call eeh_remove_device() from the bus device removal
handlers, which are called synchronously in the removal path.

In-Reply-To: <cover.1587704308.git.sbobroff@linux.ibm.com>
If a device is hot unplgged during EEH recovery, it's possible for the
RTAS call to ibm,configure-pe in pseries_eeh_configure() to return
parameter error (-3), however negative return values are not checked
for and this leads to an infinite loop.
Fix this by correctly bailing out on negative values.

* [PATCH v3 0/3] powerpc/eeh: Release EEH device state synchronously
From: Sam Bobroff @ 2020-04-24 4:58 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Nathan Lynch, Oliver O'Halloran
Hi everyone,
Here are some fixes and cleanups that have come from other work but that I
think stand on their own.
Only one patch ("Release EEH device state synchronously", suggested by Oliver
O'Halloran) is a significant change: it moves the cleanup of some EEH device
data out of the (possibly asynchronous) device release handler and into the
(synchronously called) bus notifier. This is useful for future work as it makes
it easier to reason about the lifetimes of EEH structures.
Note that I've left a few WARN_ON_ONCEs in the code because I'm paranoid, but I
have not been able to hit them during testing.
Cheers,
Sam.
Notes for v3:
I've tweaked the fix for pseries_eeh_configure_bridge() to return the correct
error code (even though it's not used) by calling an already present RTAS
function, rtas_error_rc(). However, I had to make another change to export that
function and while it does seem like the right thing to do, but I'm concerned
it's a bit out of scope for such a small fix.
Notes for v2:
I've dropped both cleanup patches (3/4, 4/4) because that type of cleanup
(replacing a call to eeh_rmv_from_parent_pe() with one to eeh_remove_device())
is incorrect: if called during recovery, it will cause edev->pe to remain set
when it would have been cleared previously. This would lead to stale
information in the edev. I think there should be a way to simplify the code
around EEH_PE_KEEP but I'll look at that separately.
