* [PATCH v4 3/6] clk: sunxi-ng: add support for Allwinner A64 DE2 CCU
From: Icenowy Zheng @ 2017-12-30 11:30 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171230113043.30237-1-icenowy@aosc.io>
Allwinner A64's DE2 needs to claim a section of SRAM (SRAM C) to work.
Add support for it.
Signed-off-by: Icenowy Zheng <icenowy@aosc.io>

Changes in v4:
- Use a struct to maintain both ccu desc and quirks as Chen-Yu Tsai
suggested.

* [PATCH v4 2/6] dt-bindings: add binding for A64 DE2 CCU SRAM
From: Icenowy Zheng @ 2017-12-30 11:30 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171230113043.30237-1-icenowy@aosc.io>
A64's Display Engine 2.0 needs a section of SRAM (SRAM C) to be claimed,
otherwise the whole DE2 memory zone cannot be accessed (kept to all 0).
Add binding for this, in order to make the DE2 CCU able to claim the
SRAM and enable access to the DE2 clock and reset registers.
Acked-by: Rob Herring <robh@kernel.org>
Signed-off-by: Icenowy Zheng <icenowy@aosc.io>
---
Changes in v4:
- Added Rob's ACK.
Changes in v2:
- Adds description of the situation when the SRAM is not claimed.

The H3/H5 SoCs have a HDMI output and a TV Composite output.
Add simplefb nodes for these outputs.

* [PATCH v4 0/6] Allwinner H3/H5/A64(DE2) SimpleFB support (Part 2)
From: Icenowy Zheng @ 2017-12-30 11:30 UTC (permalink / raw)
To: linux-arm-kernel
This patchset is the remaining part of Allwinner DE2 SimpleFB support in
Linux. Some H3/5-related patches are already applied into the sunxi
tree.
PATCH 1 adds the final SimpleFB nodes to the H3/H5 device tree. With it
applied the SimpleFB will be usable on H3/H5.
PATCH 2/3 are for the SRAM requirment of the A64 SoC; PATCH 2 is the
device tree binding of it and PATCH 3 is the implementation in DE2 CCU
of it.
PATCH 4/5 are A64 DTSI file parts; PATCH 4 adds DE2 CCU device node and
PATCH 5 adds SimpleFB device node.
PATCH 6 are A64 per-board DTS file changes, which keeps the regulator
for HVCC pin (a power supply pin on A64 SoC that is used by the HDMI
controller) on these boards.
Icenowy Zheng (6):
ARM: sunxi: h3/h5: add simplefb nodes
dt-bindings: add binding for A64 DE2 CCU SRAM
clk: sunxi-ng: add support for Allwinner A64 DE2 CCU
arm64: allwinner: a64: add DE2 CCU for A64 SoC
arm64: allwinner: a64: add simplefb for A64 SoC

To: linux-arm-kernel
In-Reply-To: <1514596392-22270-1-git-send-email-pure.logic@nexus-software.ie>
Due to the old function signature of clk_ops->round_rate
pll_clk_round_rate does a cast of an internal unsigned long
to a long. After updating clk_ops->round_rate() to be an unsigned long
though the cast isn't necessary. Remove the cast now.

bcm2835_pll_rate_from_divisor returns a long but the function calling it
returns an unsigned long. There's no reason to have a type disparity here
so tidy up the return type of bcm2835_pll_rate_from_divisor() from signed
to unsigned long.

bcm2835_pll_rate_from_divisors() returns a value directly as the return
value to round_rate(). clk_ops->round_rate() has been changed to an
unsigned long so for the sake of completeness and neatness this patch
updates the helper function to return the same data-type.

* [PATCH 01/33] clk_ops: change round_rate() to return unsigned long
From: Bryan O'Donoghue @ 2017-12-30 1:12 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1514596392-22270-1-git-send-email-pure.logic@nexus-software.ie>
Right now it is not possible to return a value larger than LONG_MAX on 32
bit systems. You can pass a rate of ULONG_MAX but can't return anything
past LONG_MAX due to the fact both the rounded_rate and negative error
codes are represented in the return value of round_rate().
Most implementations either return zero on error or don't return error
codes at all. A minority of implementations do return a negative number -
typically -EINVAL or -ENODEV.
At the higher level then callers of round_rate() typically and rightly
check for a value of <= 0.
It is possible then to convert round_rate() to an unsigned long return
value and change error code indication for the minority from -ERRORCODE to
a simple 0.
This patch is the first step in making it possible to scale round_rate past
LONG_MAX, later patches will change the previously mentioned minority of
round_rate() implementations to return zero only on error if those
implementations currently return a negative error number. Implementations
that do not return an error code of < 0 will be left as-is.

With latest perf code, it reports another error when analyse perf
data: "0x3e0 [0x50]: failed to process type: 1".
After roughly analysis, I found this is caused by one dummy event (in
the binary from offset 0xf8 to offset 0x178). Because this event type
is not set for 'PERF_SAMPLE_TIME', so the function
perf_evsel__parse_sample_timestamp() checks the event has not set
'PERF_SAMPLE_TIME' then directly bail out with error.

You could check the perf binary from [1]. Please note, this perf data
I capatured from kernel 4.14-rc6, so is it might be compatible issue
between 4.14-rc6 and 4.15?

After apply this patch set and build 'perf' tool with linking
OpenCSDv0.8.0 libs, I can everytime OpenCSD parses 'elem->elem_type'
is OCSD_GEN_TRC_ELEM_ADDR_NACC but not OCSD_GEN_TRC_ELEM_INSTR_RANGE.
As result, the 'perf' tool can dump the raw data with '-D' option but
it cannot analyze the symbol and symbol offset with below command:
./perf script -v -a -F cpu,event,ip,sym,symoff -i ./perf.data -k vmlinux
--kallsyms ./System.map
Have uploaded perf.data/vmlinux/System.map in the folder:

You seem to be using a convention by which the port represents the
whole "slot" or "PCI device" (as an entity consisting of up to 8
functions) connected to it.
That is fair enough as long as the port is not the top of a more
complex branch of the PCIe hierarchy, so maybe that case needs to be
made special somehow?
Also, I would document the convention by mentioning that the wakeup
signaled via that interrupt doesn't apply to the port itself, but to
the functions (endpoints) below it.

As long as the convention used here is clear to everybody, that is.

"suckage" ? Hehe ... the suckage should rather be stuff that cannot
sleep. Arbitrary latencies and jitter caused by too much code wanting
to be "atomic" when unnecessary are a bad thing.
In the case of clocks like the aspeed where we have to wait for a
rather long stabilization delay, way too long to legitimately do a non-
sleepable delay with a lock held, do we need to do everything in
prepare() then ?
Ben.
