* qemu-timer.c: rename qemu_timer_new_scale()David 'Digit' Turner2011-06-011-6/+6
| | | | | | | | | | | Get rid of qemu_timer_new() implementation, and update all callers to use qemu_timer_new_ms() or qemu_timer_new_ns() instead. Rename qemu_new_timer_scale() to qemu_new_timer() to follow upstream conventions. Change-Id: Id2c04f8597ec5026e02f87b3e2c5507920eb688e

* vl-android.c: Fix PC Bios search order.David 'Digit' Turner2011-06-011-46/+30
| | | | | | | | This fixes the algorithm used to search the PC Bios files. Moreover, this makes standalone builds under external/qemu just work by looking under prebuilt/common/pc-bios Change-Id: I4619565d57dc5a5b75333f6459f5bfc32b81e918
* x86: kvm: fix KVM build + enable auto-detection.David 'Digit' Turner2011-05-261-6/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the build of KVM support in the x86 emulator by copying official Ubuntu Lucid KVM headers into android/config/linux-*/ This removes the need to rely on the build machine's versions of these headers, which caused various issues. Also, by default, the emulator will now probe the system to see if it can start in KVM mode automatically. See android-kvm.c for details. You can see the result of the probing with the -verbose option. IMPORTANT NOTE: It looks like there is a bug in the KVM code when the emulator is built as a 32-bit binary, running on a 64-bit kernel, so we explicitely disable KVM when we detect this case. It's hard to tell whether this is a bug in QEMU or some versions of the KVM driver. As such, KVM only works when building the emulator as a 64-bit program. For now, this is only possible with "android-configure.sh --try-64", not the Android build system. + Add a new QEMU option (-disable-kvm) to explicitely disable KVM if needed. This is an addition to -enable-kvm which already exists (and forces usage of KVM). Change-Id: I6a397cae29ab62b1c56fce95c1ee75a4664d6688
* fix audio backend handlingDavid 'Digit' Turner2011-05-211-0/+3
| | | | | | | | | | This patch fixes a small bug where the audio backend given with the -audio <name> option was ignored. The bug was introduced during a previous integration of upstream audio changes. The old code always used the same default backend (PulseAudio). Change-Id: I7bc68df3fd3025f8a8bd1f0fd868872b7eee2017
* Fix the pc-bios search path for build trees.David 'Digit' Turner2011-05-141-2/+2
| | | | | | | | | | | This patch fixes the routine that looks for the x86 BIOS file(s) when running from the build tree (i.e. typing 'emulator' just after building the full_x86-eng product). Turns out that the files are installed under out/host/<system>/usr/share/pc-bios by our build scripts. Change-Id: I51ae849d5cdf130558d05f2386c4175dfea1e054
* Fix SDCard speed issues too.David 'Digit' Turner2011-05-121-4/+8
| | | | | | | | | It looks like we also need to set the 'cache' property to 'unsafe' when initializing the SDCard block device. Otherwise it will be mounted as O_DIRECT, making all i/o operations on the SD Card extremely slow. Change-Id: Id1a72f926c73dc6981a568f005f19cfc50f724d5
* Correct fix for snapshot saving speedDavid 'Digit' Turner2011-05-041-2/+2
| | | | | | | | | | | | | | | QEMU is a weird animal. The "snapshot" property speeds-up snapshot saving but also redirect all stores to a temporary file which is deleted when the emulator exit. Use a different property to get the desired speed-up. Note that using "writeback" instead of "unsafe" forces the use of fdatasync() which will still be horribly slow. + Argument checking in avd snapshot commands in the console. (trying to load a name-less snapshot actually crashes the emulator). Change-Id: Ie61f110f037bbb3539c7f9892cb03bee8bfec6bd
* Fix snapshot save pathetic speed.David 'Digit' Turner2011-05-041-1/+6
| | | | | | | | | | | | | | It turns out that the 'snapshot' property must be turned on on the block device corresponding to the snapshot storage file. Otherwise, the file is mounted O_DIRECT, which on my speedy machine limits the operation to a max of about 2.5 MB/s. This explains why saving snapshots was so pathetic. With this change, the save throughput is up to 278 MB/s on the same machine! Change-Id: I77c792114171a4ecaf3e3f08f64d8b3a30709f23

* Add 'emulator' launcher program.David 'Digit' Turner2011-05-021-0/+23
| | | | | | | | | | | | | | | | | | | | | | | This patch renames the current ARM-specific emulator binary to 'emulator-arm' and introduces a new tiny (less than 20KB) 'emulator' launcher program. The role of 'emulator' is to launch either 'emulator-arm' or 'emulator-x86' based on the target AVD or platform build being used. This program will be replaced in the future by what is currently known as 'emulator-ui', but is a good placeholder until this work is completed. + Move some utility functions from android/avd/info.[hc] to android/avd/util.[hc] so that 'emulator' can use them directly. IMPORTANT: For platform builds, the target architecture is detected automatically by parsing the build.prop file. For SDK AVDs however, there is no easy way to determine the target architecture, so the patch adds a new hw.cpu.arch property which can have value 'arm' or 'x86' Change-Id: I0084c196695a75c8b9230ba716b3cd2e12610ded
* New goldfish_pipe virtual device.David 'Digit' Turner2011-04-281-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new virtual hardware device named "goldfish_pipe" used to implement a very fast communication channel between the guest system and the emulator. IMPORTANT: This depends on a special kernel driver, see: https://review.source.android.com/#change,22496 Usage from the guest is simply the following: fd = open("/dev/qemu_pipe", O_RDWR); const char* pipename = "pipe:<name>"; ret = write(fd, pipename, strlen(pipename)+1); if (ret < 0) { /* could not connect to service named <name> */ } /* now you can read()/write()/close() as a normal * file descriptor to exchange data with the service. */ In addition, this implements the following pipe services in the emulator: tcp:<port> tcp:<hostname>:<port> unix:<path> opengles The 'tcp:' and 'unix:' services simply redirect to a TCP or Unix socket on the host with minimal The 'opengles' service simply connects to tcp:locahost:22468 for now. We may change this to be more configurable in the future, but that's the port number used by the current experimental OpenGL ES hardware emulation host libraries / programs. Benchmarking with a simple ping-pong program shows that the guest <-> emulator can achieve a roundtrip bandwidth of 192 MB/s (on a 2.7 Ghz Xeon PC). Using the tcp: service to talk to a ping-pong server listening on localhost reaches 102 MB/s on the same machine, using a Unix socket reaches 140 MB/s. By contrast, using standard sockets in the guest reaches only 3.8 MB/s on the same machine (and requires special privileges from the application anyway).
* Fix -qemu -vnc startup.David 'Digit' Turner2011-04-271-0/+2
| | | | | | | | | | | | Starting the emulator with something like "-qemu -vnc :1" didn't result in a valid boot sequence, due to the way our "hw-control" service is initialized. This patch fixes the issue. Note however that since a VNC client cannot send proper touch events, it can only be used as a viewer at the moment. Change-Id: Ib9b60ff7028892368547bff89b84f580344c2edd

* Set hw.keyboard.lid default value to false for API level >= 12David 'Digit' Turner2011-03-221-0/+3
| | | | | | | | | | | | | | | | | | | | | This patch modifies the emulator to extract the target API level for the AVD or the current platform release, and use it to set the default value of hw.keyboard.lid. This will *not* affect any existing AVD/platform that sets the value explicitely in its config.ini (for AVDs) or hardware.ini (for platform builds). The change is beneficial for platform builds targetting API level >= 12, because the input framework changed its the window orientation behaviour depending on the availability of a hardware lid. In short, this allows platform builds to be correctly oriented, even if they don't provide a custom hardware.ini. Fix for bug 4128604 Change-Id: I195135aae6f3c4cc11d2f01e1293f3cd6cad2f58

| | | | | | | | | | | | The differences between android/main.c and android/main-ui.c are now minimal, so remove the latter source file by moving the corresponding code into android/main-common.c Also add a -snapshot-no-time-update core option to implement the emulator-ui -no-snapshot-update-time option.

* Fix ui/core display depth mismatch.David 'Digit' Turner2011-01-201-18/+12
| | | | | | | | | | | | | | | | | This patch fixes a problem where the core's framebuffer was incorrectly initialized to a pitch of width*4 by default (instead of width*2 when using a 16-bit framebuffer). The reason for this was complex, but essentially, when the machine initialization was moved before the display one in vl-android.c, this changed the way the DisplayState was initialized. Also get rid of the useless and confusing "display_state" global in vl-android.c (not the same than "display_state" in console.c) Change-Id: If8e2b8baf7ccaeedcb66da0174cc529521d67a60
