old_chunk has already been unpinned therefore the address
could be incorrect
NULL will ensure buflib_shrink uses the same start address

stupid bug on my part font_filename was pointing to a movable
alloc therefore that data could be moved out from under the returned pointer
instead pin the internal calls to core_get_data and
remove font_filename in favor of a function that checks if a
filename matches the loaded font as this was all it was used for anyway

Apparently a response is coming out of nowhere and tripping this
check. I can't be bothered to look into it; it would be better to
just update the ARC USB driver to the new control request API...

The perceived loudness change of a change in volume depends
on the listening volume: at high volumes a 1 dB increment is
noticeable, but at low volumes a larger increment is needed
to get a comparable change in loudness.
Perceptual volume adjustment accounts for this fact, and
divides the hardware volume range into a number of steps.
Each step changes the dB volume by a variable amount, with
most of the steps concentrated at higher volumes. This
makes it possible to sweep over the entire hardware volume
range quickly, without losing the ability to finely adjust
the volume at normal listening levels.
Use "Volume Adjustment Mode" in the system settings menu
to select perceptual volume mode. The number of steps used
is controlled by "Number of Volume Steps". (Number of steps
has no effect in direct adjustment mode.)
It's still possible to set a specific dB volume level from
the sound settings menu when perceptual volume is enabled,
and perceptual volume does not affect the volume displayed
by themes.

The newer players have some changed hardware, but most importantly
the line out now appears to be routed through the stereo switch
instead of being hardwired directly off the DAC.
Disable muting the headphone amp, enable switching the stereo switch,
and rename some of the GPIOs to be more generic since the DAC,
headphone amp, and stereo switch all appear to have changed.

It seems connecting an iPod Video to a Mac triggers the null
request check, resulting in a panic. Ignoring the error with
a bare return "fixes" it and allows the iPod to connect. This
isn't ideal though, because it could silently introduce bugs
on other targets.
The likely cause of this is the host sending control requests
too fast, or a driver problem (the Video uses the ARC driver,
which is still on the legacy interface), with multiple requests
getting queued at once. Since the USB core expects to deal with
only one request at a time, the second response trips the check.
Try to handle this situation a bit more gracefully by detecting
overlapped requests and returning a STALL to the host when it
occurs. At this point the USB stack is able to safely handle a
new request.

These are more efficient than separate pin/unpin calls because
pin count increment and decrement can be done cheaply when the
data pointer is known.
Secondly, pinned access can be made safe against preemption by
hardware interrupts or other CPU cores; buflib_get_data() can't.
This makes it more useful under different threading models and
for SMP targets; both of which are not particularly relevant to
Rockbox now, but might be in the future.

This is intended for improving the effectiveness of tools like
ASAN when debugging memory errors in the sim. It's not meant to
be a serious allocator for hosted targets.
Enable it by changing the buflib backend in config.h.

Gate buflib_get_data() checking, debug printing, and buflib
integrity checks behind individual defines in buflib.h, and
turn them all off by default. If needed, they can be turned
on manually when compiling.
The buflib debug menu is only available if debug printing is
enabled, so after this commit it will no longer be included
in normal builds -- it isn't very useful to end users.

Removing the variable-length name in the middle of buflib metadata
makes it a lot easier to deal with.
Change-Id: I6eaf236c2285cae40fb6ff0fa5acf827972cdd8b
|
|
The CRC is a fairly useless safety check because we already
have specific checks to validate the metadata, and CRCs are
only verified before calling the move callback. Removing the
check should not significantly reduce buflib's robustness.

Remove the name handling code, but leave the allocation structure
otherwise untouched; it's as if all callers provided a NULL name.
The public API still accepts names but names are no longer stored
or returned.

Naming your allocations is more of a debugging feature; it's a
bad idea to abuse this feature for storing some random string.
The font code does exactly that to remember the path used to
load a font, and it's the only code that uses buflib names in
this way.
Store the path inside the font allocation instead as a regular
char array. For simplicity it's MAX_PATH sized, so this'll use
a bit more memory than the buflib name method, maybe 1-2 KiB if
a few fonts are loaded.

It's usually only called from init() in main.c, so this is safe.
There is one more call in system-dm320.c from system_init(), but
that's also "safe". I don't know if it's okay to call i2c_init()
twice, but presumably it works...

On single-core targets, system_init() is only called from init()
in main.c, which is also INIT_ATTR, so this is safe.
Multi-core targets additionally call system_init() from cop_main(),
which isn't marked INIT_ATTR. I'm fairly certain that it would be
safe to add INIT_ATTR to cop_main() with a bit of refactoring, but
I don't have a way of testing it. So for now, leave INIT_ATTR off
for multi-core targets.

chunk_alloc allows arrays (or any data) to be allocated in smaller chunks
you have to save the indices..
variable data will have variable indices you need to
store these as [chunk_alloc] doesn't keep track
if you have a fixed size for each
alloc you can do indice / sizeof(data)
or index * sizeof(data) to convert
Lots of debug stuff still in and it needs optimization
User provides chunk_size and max_chunks
max_chunks * struct chunk will be allocated at start
with (1) chunk_size allocation initially
alloc_chunk() with size = 0 shrinks the last allocation to the size of the data used
add OOM checks on buflib_alloc -- oops
move bytes available to the header -- less memory per chunk & better alignment
keep track of the current in use chunk index -- should speed things up a bit
Now allows:
realloc chunk header
larger allocations than chunk size
reallocs smaller than existing will shrink the current array
rather than alloc a new and copy data
Comments welcome :)

is missing
HAVE_MULTIVOLUME is a subset of HAVE_MULTIDRIVE
in normal circumstances they are interchangable
but when the internal drive is not found the assumption falls apart
at the moment most of the bootloader are less selective about what drives/volumes
they will mount therefore the volume might not match between what the bootloader
returns for multiboot and what the firmware sees
updating bootloaders will fix this but it should probably be made more robust
at the same time
