* Fix Mac and Windows builds.David 'Digit' Turner2011-05-261-0/+3

* x86: kvm: fix KVM build + enable auto-detection.David 'Digit' Turner2011-05-266-1/+1931
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | This patch dumps the content of the hardware configuration file when the -verbose option (or equivalent -debug-init) is used. This is useful to determine exactly what is launched when debugging emulator issues. Change-Id: I101b87cddb12c603b43420ea72bb357fc33f327d

| * Fix -snapshot-list option.David 'Digit' Turner2011-05-052-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes -snapshot-list work properly. More specifically: - If the AVD has snapshotting enabled, the emulator will find the appropriate file if you don't use -snapstorage. - If the AVD has no snapshot support, the emulator will print a user-friendly message to explain that. - If you're in the Android build, the emulator indicates that -snapstorage <file> is mandatory.

* | Fix "avd name" bug.David 'Digit' Turner2011-05-051-4/+1
|/ | | | | | | | | | | | | | The console's 'avd name' command returned "unknown" incorrectly. This was due to a missing option when invoking the core, even in the standalone case. Fixes bug 3454261 Change-Id: I5d4e346591e13bd7f525ad81953fd2d17c8f27b7 NOTE: This is similar to the tools_r10 quick fix at https://review.source.android.com/#change,22735, only simpler.

| * Fix ANDROID_SDK_HOME handling.David 'Digit' Turner2011-05-041-12/+5

* | Correct fix for snapshot saving speedDavid 'Digit' Turner2011-05-041-0/+18
|/ | | | | | | | | | | | | | | 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

| * Add 'emulator' launcher program.David 'Digit' Turner2011-05-028-224/+657
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* | Use user-specific directory for temporary files.David 'Digit' Turner2011-05-021-2/+8

* New goldfish_pipe virtual device.David 'Digit' Turner2011-04-283-793/+525
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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' Turner2011-04-274-7/+22
| | | | | | | | | | | | 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

* Fix framebuffer width/height computation.David 'Digit' Turner2011-03-251-2/+2
| | | | | | | | | | | | | | | This patch fixes a bug in the skin parsing code that computes the dimensions of the emulated framebuffer. The bug had the following symptoms: - The vertical framebuffer size reported by the 'events' device was always 640 (the default), independent of the skin's dimensions and emulated 'framebuffer' device dimensions. As such, all touch event Y coordinates were scaled by the system by 480/640 when running inside a HVGA screen. Change-Id: I8c67f011ee3929ef25cbf2c858ee800f277c516c
* Set hw.keyboard.lid default value to false for API level >= 12David 'Digit' Turner2011-03-226-60/+288
| | | | | | | | | | | | | | | | | | | | | 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

* Fix write of disk sizes in ini files.David 'Digit' Turner2011-03-151-11/+14
| | | | | | | | The old implementation always expressed the size as multiples of kilobytes due to an improper order to size checks. For example, 66MB was written as '67584k' instead of '66m', which is correct but sub-optimal. Change-Id: I6365bf4c269ed7d213043182a8ae501713798b8f
