From b1e4bd55208709c7329f1fbf393fdefbddf3845d Mon Sep 17 00:00:00 2001 From: Arisotura Date: Thu, 22 Sep 2022 20:32:27 +0200 Subject: merge local_wifi (#1516) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * attempt at betterer wifi * add preliminary sync mechanism * fix gaps in wifi implementation * move local-MP comm to its own module instead of cramping Platform.cpp * remove some stupid cruft * as you wish, Sorer (starting work on shared-memory system) * shared-memory IPC that actually works (albeit Windows-only for now) * shut up logging from NULL writes on ARM7 (ffs Nintendo learn to code) * get this somewhat good * leave client sync mode when host deauths. makes download play actually work. * start implementing MP-comm error handling * * add MP-reply error counters * feeble attempt at fixing slowdown/desync/etc problems * somewhat better exchange/sync method * * when entering power-saving mode, be sure to finish transferring the current frame first * fix misc bug due to old cruft leftover makes for a more stable connection * remove a bunch of cruft * set wifi time interval to 34 cycles instead of 33. games seem sensitive to the general timing of wifi vs the rest of the system, and this seems to make things run better, atleast until I rewrite this to use a proper scheduler. * more graceful handling of disconnects * deal with FIFO overflow more gracefully * BAHAHAHAHAHAHAHAHHHH THE SNEAKY BASTARDS so, when the DS receives a beacon with the right BSSID that beacon's timestamp is copied to USCOUNTER * attempt at making the connection process smoother for weird games * * begin adding POWCNT2, only applies to wifi for now * begin work on wifi scheduler * implement the shitty timers * add the RF wakeup thing * begin work on receiving frames. for now it can just receive melonAP beacons, but hey, it's a start. * add enough TX functionality that online wifi is a possibility again. * there are problems with this scheduler thing. committing it anyway * kind of a rollback... we're gonna work out a compromise on this, I guess * don't transmit shit if RXCNT.bit15 isn't set * move RX-finish to its own function. more accurate filtering. implement RXFILTER. * remove some cruft * fix some of the shittiness when trying to connect more than two players * fix some more shittiness * fix more wifi shittiness (mainly don't try to receive shit while sending a frame) * run wifi every 8µs. improves performance. * fix IRQ14/IRQ15 * make this work under Linux * Make it work on macOS, for now using a custom sem_timedwait implementation. If anyone knows anything about mach ports and have an idea for how to make this work using mach IPC, please do let me know. * 25ms seems like a good timeout * begin work on proper multiplayer UI shito. for now, determine a global instance ID, and derivate the system MAC from it. remove 'randomize MAC' option. * finish removing RandomizeMAC * lay groundwork for instance-unique config * work some on the UI... make it not labelled Fart * more UI work: make it explicit that some things are instance-unique * separate firmware files for multiplayer instances * make instances save to different save files, too * more UI work, make things somewhat less shitty * lay base for the multiplayer settings dialog * actually hook up most of that dialog * actually implement the fun audio settings * ensure all the wifi shit is properly savestated and reset. properly update timings for the wifi region when wifi is disabled. * add more fun labels * * ignore WEP frames if WEP is off * implement RX_LEN_CROP * fake enough of WEP processing to make Inazuma Eleven work * * do not copy more ROM banner data than actually needed * avoid trying to read out of bounds if the banner offset is bad * Fix oversight with the preferences action causing the build to fail on macOS Co-authored-by: Nadia Holmquist Pedersen --- src/frontend/qt_sdl/AudioSettingsDialog.cpp | 14 + src/frontend/qt_sdl/AudioSettingsDialog.ui | 11 +- src/frontend/qt_sdl/CMakeLists.txt | 4 + src/frontend/qt_sdl/Config.cpp | 402 +++++++------ src/frontend/qt_sdl/Config.h | 6 +- src/frontend/qt_sdl/FirmwareSettingsDialog.cpp | 20 +- src/frontend/qt_sdl/FirmwareSettingsDialog.h | 1 - src/frontend/qt_sdl/FirmwareSettingsDialog.ui | 13 +- .../qt_sdl/InputConfig/InputConfigDialog.cpp | 7 + .../qt_sdl/InputConfig/InputConfigDialog.ui | 145 ++--- src/frontend/qt_sdl/LAN_PCap.cpp | 12 +- src/frontend/qt_sdl/LocalMP.cpp | 634 +++++++++++++++++++++ src/frontend/qt_sdl/LocalMP.h | 45 ++ src/frontend/qt_sdl/MPSettingsDialog.cpp | 73 +++ src/frontend/qt_sdl/MPSettingsDialog.h | 65 +++ src/frontend/qt_sdl/MPSettingsDialog.ui | 142 +++++ src/frontend/qt_sdl/PathSettingsDialog.cpp | 7 + src/frontend/qt_sdl/PathSettingsDialog.ui | 71 +-- src/frontend/qt_sdl/Platform.cpp | 277 ++++----- .../PowerManagement/PowerManagementDialog.cpp | 7 + .../PowerManagement/PowerManagementDialog.ui | 79 +-- src/frontend/qt_sdl/ROMManager.cpp | 12 + src/frontend/qt_sdl/WifiSettingsDialog.cpp | 5 +- src/frontend/qt_sdl/WifiSettingsDialog.ui | 133 ++--- src/frontend/qt_sdl/main.cpp | 155 ++++- src/frontend/qt_sdl/main.h | 11 + src/frontend/qt_sdl/sem_timedwait.cpp | 488 ++++++++++++++++ src/frontend/qt_sdl/sem_timedwait.h | 8 + 28 files changed, 2234 insertions(+), 613 deletions(-) create mode 100644 src/frontend/qt_sdl/LocalMP.cpp create mode 100644 src/frontend/qt_sdl/LocalMP.h create mode 100644 src/frontend/qt_sdl/MPSettingsDialog.cpp create mode 100644 src/frontend/qt_sdl/MPSettingsDialog.h create mode 100644 src/frontend/qt_sdl/MPSettingsDialog.ui create mode 100644 src/frontend/qt_sdl/sem_timedwait.cpp create mode 100644 src/frontend/qt_sdl/sem_timedwait.h (limited to 'src/frontend/qt_sdl') diff --git a/src/frontend/qt_sdl/AudioSettingsDialog.cpp b/src/frontend/qt_sdl/AudioSettingsDialog.cpp index a9b3ade..4beefaf 100644 --- a/src/frontend/qt_sdl/AudioSettingsDialog.cpp +++ b/src/frontend/qt_sdl/AudioSettingsDialog.cpp @@ -67,6 +67,20 @@ AudioSettingsDialog::AudioSettingsDialog(QWidget* parent) : QDialog(parent), ui( bool iswav = (Config::MicInputType == 3); ui->txtMicWavPath->setEnabled(iswav); ui->btnMicWavBrowse->setEnabled(iswav); + + int inst = Platform::InstanceID(); + if (inst > 0) + { + ui->lblInstanceNum->setText(QString("Configuring settings for instance %1").arg(inst+1)); + ui->cbInterpolation->setEnabled(false); + ui->cbBitrate->setEnabled(false); + for (QAbstractButton* btn : grpMicMode->buttons()) + btn->setEnabled(false); + ui->txtMicWavPath->setEnabled(false); + ui->btnMicWavBrowse->setEnabled(false); + } + else + ui->lblInstanceNum->hide(); } AudioSettingsDialog::~AudioSettingsDialog() diff --git a/src/frontend/qt_sdl/AudioSettingsDialog.ui b/src/frontend/qt_sdl/AudioSettingsDialog.ui index d7cfadd..8fc38d9 100644 --- a/src/frontend/qt_sdl/AudioSettingsDialog.ui +++ b/src/frontend/qt_sdl/AudioSettingsDialog.ui @@ -7,7 +7,7 @@ 0 0 482 - 256 + 301 @@ -23,6 +23,13 @@ QLayout::SetFixedSize + + + + Configuring settings for instance X + + + @@ -76,7 +83,7 @@ - <html><head/><body><p>The bitrate of audio playback.

Mac OS X is one example, at least up to + * and including version 10.6 (Leopard). If such a function is needed, + * this code provides a reasonable implementation, which I think is + * compatible with the standard version, although possibly less + * efficient. It works by creating a thread that interrupts a normal + * sem_wait() call after the specified timeout. + * + * Call: + * + * The Linux man pages say: + * + * #include + * + * int sem_timedwait(sem_t *sem, const struct timespec *abs_timeout); + * + * sem_timedwait() is the same as sem_wait(), except that abs_timeout + * specifies a limit on the amount of time that the call should block if + * the decrement cannot be immediately performed. The abs_timeout argument + * points to a structure that specifies an absolute timeout in seconds and + * nanoseconds since the Epoch (00:00:00, 1 January 1970). This structure + * is defined as follows: + * + * struct timespec { + * time_t tv_sec; Seconds + * long tv_nsec; Nanoseconds [0 .. 999999999] + * }; + * + * If the timeout has already expired by the time of the call, and the + * semaphore could not be locked immediately, then sem_timedwait() fails + * with a timeout error (errno set to ETIMEDOUT). + * If the operation can be performed immediately, then sem_timedwait() + * never fails with a timeout error, regardless of the value of abs_timeout. + * Furthermore, the validity of abs_timeout is not checked in this case. + * + * Limitations: + * + * The mechanism used involves sending a SIGUSR2 signal to the thread + * calling sem_timedwait(). The handler for this signal is set to a null + * routine which does nothing, and with any flags for the signal + * (eg SA_RESTART) cleared. Note that this effective disabling of the + * SIGUSR2 signal is a side-effect of using this routine, and means it + * may not be a completely transparent plug-in replacement for a + * 'normal' sig_timedwait() call. Since OS X does not declare the + * sem_timedwait() call in its standard include files, the relevant + * declaration (shown above in the man pages extract) will probably have + * to be added to any code that uses this. + * + * Compiling: + * This compiles and runs cleanly on OS X (10.6) with gcc with the + * -Wall -ansi -pedantic flags. On Linux, using -ansi causes a sweep of + * compiler complaints about the timespec structure, but it compiles + * and works fine with just -Wall -pedantic. (Since Linux provides + * sem_timedwait() anyway, this really isn't needed on Linux.) However, + * since Linux provides sem_timedwait anyway, the sem_timedwait() + * code in this file is only compiled on OS X, and is a null on other + * systems. + * + * Testing: + * This file contains a test program that exercises the sem_timedwait + * code. It is compiled if the pre-processor variable TEST is defined. + * For more details, see the comments for the test routine at the end + * of the file. + * + * Author: Keith Shortridge, AAO. + * + * History: + * 8th Sep 2009. Original version. KS. + * 24th Sep 2009. Added test that the calling thread still exists before + * trying to set the timed-out flag. KS. + * 2nd Oct 2009. No longer restores the original SIGUSR2 signal handler. + * See comments in the body of the code for more details. + * Prototypes for now discontinued internal routines removed. + * 12th Aug 2010. Added the cleanup handler, so that this code no longer + * leaks resources if the calling thread is cancelled. KS. + * 21st Sep 2011. Added copyright notice below. Modified header comments + * to describe the use of SIGUSR2 more accurately in the + * light of the 2/10/09 change above. Now undefs DEBUG + * before defining it, to avoid any possible clash.
