[Bug 1590804] Re: fontconfig initialization spends most of its time parsing XML configuration files in /etc/fonts/conf.d/

2016-07-01 Thread Alberto Aguirre
So actually, fontconfig does not cache conf files at all... it caches
fonts but not conf files...

fontconfg needs support to also cache the result of the parsing of the
xml config file parsing. It seems a low priority effort for less than a
35ms improvement in startup.

Also FcInitReinitialize and FcInitBringUptoDate both will do the same
thing the first time is called in the process, so wouldn't help for
startup either.

2016-03-11 Thread Alberto Aguirre
Hi Peter,

So I just tried to replicate this in my E5 but haven't been able to.

How frequently do you encounter this issue? Like every 10 times you
receive a call, how many of those do you encounter the issue reported?

Hi Peter,

I have a suspicion your proximity sensor may not be working correctly.
Could you install this ProximityCheck app in your phone:

[Bug 1633690] Re: byt-max98090 not working on linux-image-4.8.0-22-generic on baytrail hardware

2016-12-01 Thread Alberto Aguirre
There are a couple of issues: first the byt-max98090 is not enabled by
default due to conflict with other sound codecs (see:
https://lkml.org/lkml/2016/8/11/741)

The driver configuration is such that SND_SST_IPC_API needs to be
disabled for SND_SOC_INTEL_BYT_MAX98090_MACH to be selectable. To
disable SND_SST_IPC_API all other drivers dependant on it have to be
disabled as well.

This means on distribution can only support either a baytrail max98090
or all other sound codecs at the moment (need to wait for upstream
resolution).

The second issue is the codec cannot be probed unless gpio can use CRS
(see
https://github.com/GalliumOS/linux/commit/cee2747204b11b63042777dd01fe336e9b49fef0
#diff-32b258ffa70fb36e4c510fca532f6d23R21 )

In the mean time while the issue is worked on by upstream, you can build
your own kernel with the attached patches.

See https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel

This is how I built it on my machine:
git clone git://kernel.ubuntu.com/ubuntu/ubuntu-yakkety.git --depth 1
git am bytmax98090-kernel-patches/*.patch
fakeroot debian/rules clean
DEB_BUILD_OPTIONS=parallel=8 fakeroot debian/rules binary-generic

Also note you still need to have the asound.state from chromeOS which
you can get at: https://github.com/GalliumOS/galliumos-
baytrail/blob/master/var/lib/alsa/asound.state

You can also use my ppa at your own risk :) at:
https://launchpad.net/~albaguirre/+archive/ubuntu/linux-bytmax98090/

I use this ppa to get sound on an Acer CB3-111 (GNAWTY), booting with
BOOT_STUB firmware from MrChromebox (https://mrchromebox.tech/#fwscript)

[Bug 1655411] [NEW] Cannot enable VC4 graphics driver on RPi 3

2017-01-10 Thread Alberto Aguirre
Public bug reported:

It seems the VC4 device tree overlay is not applied by the Rpi firmware.

I tried adding dtoverlay=vc4-kms-v3d and adding a corresponding
.../overlays/vc4-kms-v3d.dtbo file but it seems the Rpi bootloader does
not apply the overlay at all.

I merged vc4-kms-v3d.dtbo into bcm2710-rpi-3-b.dtb using a dtmerge utility 
compiled by pulling pieces from (https://github.com/raspberrypi/userland and 
https://github.com/dgibson/dtc)
The result is here: https://github.com/albaguirre/dtmerge

With this new device tree binary blob, The VC4 driver (as a module)
loads (and you can see /dev/dri/ entries)

I also played around with the tip of u-boot tree
(git://git.denx.de/u-boot.git) which has support to apply device tree
overlays - it applied fine and VC4 is at least recognized but the driver
cannot initialize properly.

Any idea on what magic incantation is needed for the RPi loaders
(start.elf etc) to apply the vc4 overlay?

Turns out we simply need to use the latest firmware loader blobs, then
the vc4 overlay is applied correctly while using u-boot.

@Peter, that would explain the behavior then.

"So, is this maybe a hardware defect? In a series of devices of the same
model?"

That's a possibility; A look at the proximity device driver and/or
sensor stack wouldn't hurt though...

[Bug 1337481] Re: Crash in libmirclient on app exit on phone

2014-07-09 Thread Alberto Aguirre
It looks to me like memory corruption from the QT stack:

Maybe it's a similar instance to this QT bug: https://bugreports.qt-

[Bug 1337481] Re: Crash in libmirclient on app exit on phone

2014-07-09 Thread Alberto Aguirre
Note I rebuilt libmirclient with the native arm compiler (on a n7
device) and I can't reproduce the issue either like that.

However just navigating to Accounts then clicking on Ubuntu One and
going back triggers the stack above, so I suspect a double free by the
QT QML GC is also leading to the stack trace in the original report.

Here's a stack trace with symbols of what I'm seeing:

[Bug 1339700] Re: Device locks randomly on welcome screen

2014-07-09 Thread Alberto Aguirre
Yeah it's a deadlock in mir, specifically between the compositor Thread
and the main loop:

The TimeoutFrameDroppingPolicy has timedout, so it owns the internal
alarm mutex and attemps to drop a frame, so it waits for the BufferQueue
mutex.

The compositor thread is releasing a buffer, so it calls
BufferQeueue::compositor_release, which owns the BufferQueue mutex and
attempts to update the TimeoutFrameDroppingPolicy (since a buffer is
being freed) but it waits to own the internal alarm mutex so deadlock.

[Bug 1340510] Re: session screen seen upon quick power key strike

2014-08-25 Thread Alberto Aguirre
The greeter is shown when it receives the DisplayPowerStateChange with
an off status signal which is only emitted after the compositor thread,
display and back-light have been shut off.

My plan was to expand the DisplayPowerStateChange signal with a "will
power off soon" status and have some sort of ack system, (with a
suitable timeout) which shells could register for to allow for short
screen lock animations  - which I think the greeter lock screen was
supposed to be.

[Bug 1458694] Re: [vivid-overlay] unity8 fails to start on the emulator

2015-07-14 Thread Alberto Aguirre
The input stub error message is inconsequential, mir is simply scanning
all the modules in that directory and finds the appropriate one:
"[1432595003.685416] Platform Loader: Selected driver: android (version
0.13.0)"

The real issue is Qt not being able to create a window: "Cannot create
window: no screens available"

I suspect qtmir does not create any screens maybe because mir's 
DisplayConfigurationOutput does not enumerate any outputs. 
A run of mir-out inside the emulator should provide some initial leads.
