For many years, QEMU has had a compile time restriction on how
many serial port devices you can create and configure with the
-serial argument. This is 4, largely because for x86 PC the
traditional number of ISA serial devices is 4, and nobody's
ever changed the limit since.
This patchset drops the compile time limit.
The first patch removes an unnecessary check in hw/char/serial
that insisted that it was not talking to a NULL chardev.
Our newly set direction is that we want to allow NULL chardev
pointers, rather than requiring UARTs and boards to create
"null" backends, so drop the check. (I have looked at the code
and it should all be fine with a NULL pointer here, including
the tricky bit where qemu_chr_fe_add_watch() returns 0 and
the required behaviour is "insta-drain the FIFO".)
The next 4 patches drop unnecessary creations of "null" chardevs.
These have to go here because in most cases they were writing
back to the serial_hds[] array, which is about to go away.
Patch 6 implements an accessor function serial_hd() which can
be used to replace direct reads of serial_hds[].
Patch 7 is purely mechanical and replaces serial_hds[x]
with serial_hd(x).
Patches 8 through 11 remove or rename various uses of the
MAX_SERIAL_PORTS #define that shouldn't really be using it.
Patch 12 then makes the serial_hds array be dynamically
reallocated.
Patch 13 adds a "what actually is the highest serial_hds entry"
function for the benefit of spapr, which is the only remaining
user of MAX_SERIAL_PORTS.
Testing: I tested mips-malta and imx6 by hand; others are only
tested via 'make check' (which did find some bugs for me!)
thanks

Currently the serial.c realize code has an explicit check that it is not
connected to a disconnected backend (ie one with a NULL chardev).
This isn't what we want -- you should be able to create a serial device
even if it isn't attached to anything. Remove the check.

Following commit 12051d82f004024, UART devices should handle
being passed a NULL pointer chardev, so we don't need to
create "null" backends in board code. Remove the code that
does this and updates serial_hds[].
(fsl-imx7.c was already written this way.)

Provide an accessor function serial_hd() to return the Chardev
(if any) associated with the numbered serial port. This will
be used to replace direct accesses to the serial_hds[] array,
so that calling code doesn't need to care about the size of
that array.

Change all the uses of serial_hds[] to go via the new
serial_hd() function. Code change produced with:
find hw -name '*.[ch]' | xargs sed -i -e 's/serial_hds\[\([^]]*\)\]/serial_hd(\1)/g'

Remove checks on MAX_SERIAL_PORTS that were just checking whether
they were within bounds for the serial_hds[] array and falling
back to NULL if not. This isn't needed with the serial_hd()
function, which returns NULL for all indexes beyond what the
user set up.

The handling of NULL chardevs in exynos4210_uart_create() is now
all unnecessary: we don't need to create 'null' chardevs, and we
don't need to enforce a bounds check on serial_hd().

The ISA serial port handling in serial-isa.c imposes a limit
of 4 serial ports. This is because we only know of 4 IO port
and IRQ settings for them, and is unrelated to the generic
MAX_SERIAL_PORTS limit, though they happen to both be set at
4 currently.
Use a new MAX_ISA_SERIAL_PORTS wherever that is the correct
limit to be checking against.

The superio device has a limit on the number of serial
ports it supports which is really only there because
it has a fixed-size array serial[]. This limit isn't
related particularly to the global MAX_SERIAL_PORTS limit,
so use a different #define for it.
(In practice the users of superio only ever want 2 serial ports.)

Instead of having a fixed sized global serial_hds[] array,
use a local dynamically reallocated one, so we don't have
a compile time limit on how many serial ports a system has.

Create a new function max_serial_hds() which returns the number of
serial ports defined by the user. This is needed only by spapr.
This allows us to remove the MAX_SERIAL_PORTS define.

These are in the "mechanical change only" patch, so I didn't

Just one question, would it make sense to use a GPtrArray instead?

Hmm. Looking at the GPtrArray API there's no API for
"tell me the length of this pointer array", so we'd still
have to do the manual bookkeeping for that. And we don't
need most of the functionality it provides. So it doesn't
really seem like it gains us much over g_renew() to me.

What about naming it serial_hds_count() to keep this under the serial_
namespace? And about using a size_t for num_serial_hds?

GPtrArray is a public struct, so you can use array->pdata and
array->len. There is a disadvantage, which is that you lose type-safety
on dereference.

The F81866A and IT8783 have 6 uarts :)
For this reason I'd prefer to dynamically allocate
ISASuperIODevice->serial, I might add that later on top of your series.

If I get the EXYNOS 4210 data sheet right, this chip has only 4 channels
indeed:
http://www.samsung.com/global/business/semiconductor/file/product/Exynos_4_Dual_45nm_User_Manaul_Public_REV1.00-0.pdf
So I think you should at least keep an "assert(channel < 4)" in here?
Apart from that, the patch looks sane to me, so when you add that assert():

In case you respin: I think you could do this without the index variable
and just use num_serial_hds directly instead (just a matter of taste,
though).

This file models a single UART, I don't think a such assert belongs here.
Although it is named EXYNOS4210, I'm pretty sure it should works to
model UARTs from other SoCs from the Exynos4xxx series.
There are no restriction on newer SoCs to have > 4 UARTs.
For this particular Exynos4210 SoC, the 4 channels are correctly limited
in exynos4210_init().

Phil.

These kinds of cleanup are in later patches in the series --
this one is kept strictly to the purely-mechanical sed change,
as otherwise it would be a bit awkward to review I thought.

I agree that's probably a good change to make, but it's also
a behavioural change (we would go from only creating serial
devices where -serial args are given, to always creating
them). I wanted to generally avoid having any behavioural
changes in this series.

Hazard of pure-mechanical-change cleanup is that it
doesn't include coding-style fixes, but it's no
worse than it was before.

It is in the fsl-imx6 case:

OK, makes sense.

This doesn't seem worthwhile though.
Since the rename of max_serial_hds is the only change here, I
propose to apply this to master (fixing up the function name in
this patch in the process), to reduce the number of conflicts
with other changes currently in-flight.

Applied to master, with minor tweak in patch 13.
I only realised when I came back to here that I'd forgotten
about checkpatch's preference for not zero-initializing
static globals; I'll send a fixup patch for that.
