* | | network: close each bsd fd once and drop unwanted or malformed room packetscirakg28 hours2-19/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two threads closing the same fd both copied the descriptor and both called Close(), so a host socket could be closed twice, and the second closesocket could hit an unrelated socket that had reused the host fd. CloseImpl now frees the slot under file_descriptors_mutex first and only that thread closes the socket; the other gets EBADF. OnProxyPacketReceived decompressed every room packet when any fd had a socket, including native sockets and proxy sockets on other ports. Sockets now report through AcceptsProxyPacket whether they want a packet, and only those are collected, so an unwanted packet is not decompressed. DecompressDataZSTD passed the frame's declared size straight to the vector constructor, so a malformed or unsized frame from a room member threw on the room thread. The new TryDecompressDataZSTD rejects invalid, unsized and oversized frames, and bsd drops such packets with a warning. DecompressDataZSTD now returns an empty vector for them instead of throwing.

| * | | nx2: video decoder: keep post-stream release fences pendingJavier29 hours1-2/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bananza's movie player acquires one decoded frame every time a released output image's fence completes, and aborts (2111-3604) when the ring is empty. Completing those fences at once after the end of a stream (the Mario Kart World workaround) made it acquire from an empty ring the moment its cutscene movies ended. Released images now keep their normal pending fence after the end of a stream. Stop (207) and Finalize (115) complete every fence handed out so far, so a client that waits on its returned images after a movie is still released when it stops the decoder. EDEN_NX2_VDEC_EOS_RELEASE_NOW=1 restores the old immediate completion; EDEN_NX2_VDEC_TRACE=1 logs every decoder call. Tested on Bananza: the post-breakout cutscene movie ends and gameplay continues (mining tunnel). Mario Kart World not retested. Assisted-by: Claude (Anthropic) for investigation and code.

* | | network: keep fcntl modes across MSG_DONTWAIT and decompress room packets oncecirakg29 hours2-36/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A receive with MSG_DONTWAIT restored the blocking mode from the descriptor copy taken before the call. When fcntl(SETFL, O_NONBLOCK) ran during the receive, the fd kept reporting O_NONBLOCK while its socket blocked again. Receives now switch the mode only for MSG_DONTWAIT and read the current flags under file_descriptors_mutex at both ends, and SETFL changes the mode and the stored flags in the same critical section. OnProxyPacketReceived decompressed each room packet once per matching socket while holding file_descriptors_mutex, so every bsd call waited for it. It now copies the distinct sockets under the lock, decompresses once without it and delivers the result. Also reject fd == MAX_FD in IsFileDescriptorValid and PollImpl, which read past the table, and guard the ProxySocket blocking and receive timeout setters with packets_mutex, matching their reader.

* | | network: keep bsd sockets alive across concurrent close and fix room gapscirakg29 hours3-135/+144
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bsd runs on three host threads, but its calls kept a raw reference into the shared descriptor table while they used a socket. A close() on another thread could then destroy the socket mid-call. Waking a blocked room recv() on close made this happen every time. Every call now works on a copy of the descriptor taken under the table lock, poll() keeps its sockets alive while it waits, and close() resets the slot only if it still holds the same socket. accept() picked a free fd before blocking and only locked the write, so another thread could publish a socket in the same slot. It now picks and writes the fd in one critical section after Accept() returns. dup() now re-checks the source fd under the lock. A duplicated fd shares its socket, so the room packet loop queued each packet once per fd. Deliver it once per socket. NIFM: when the selected host adapter is missing, the room still works and IsNetworkAvailable reports it, but GetCurrentNetworkProfile returned an empty profile. Report a wired room profile in that case, and put the room address on the first adapter in EnumerateNetworkInterfaces. Assisted-by: Claude Opus 5.5 (investigation and implementation)
* | | network: fix room socket races and share the room network checkcirakg29 hours3-48/+72

Bind the callback once. The room thread walked the descriptor table without a lock while bsd created and closed sockets, so it could reach a destroyed or not yet created socket. Guard the table with a mutex, and publish a socket only after it is created and initialized. Check airplane mode before an fd is taken, so a refused socket no longer leaks its slot. ProxySocket now initializes protocol, decompresses packets outside the packet lock without copying the compressed data first, and keeps a read offset for partial TCP reads instead of erasing from the front. Add Network::GetRoomIPv4Address(), set only in the Joined and Moderator states. NIFM uses it for network availability and for every reported address, including EnumerateNetworkInterfaces and GetCurrentIpAddress, so no call reports the room address while another rejects the network.

With the GPU split (Low GPU accuracy) the GPU thread defers queued functions to its back, but its front reads the command lists: it read the lists submitted after a map through GPU addresses that weren't mapped yet. Pokopia stopped after its first frame. Add GPU::MapInOrder for the GMMU maps and the sparse tile remaps. It runs in order like RunInOrder, and with the split it runs on the front after draining the back, before the front reads further command lists. The service thread still never takes the texture cache lock, and the back is idle while the map changes the caches. Unmaps and the other queued work still run on the back.

Games submit command lists before writing them: the lists wait behind a semaphore acquire, and the game writes their commands just before it releases the acquire (Mario Kart World after present). The copies of those lists were stale. Pokopia stopped after its first frame on macOS: its GPU never reached the fence the game spun on (EDEN_NX2_PB_SNAPSHOT=0 made it run again). Count each channel's suspensions on an acquire and the resumes after them, and record the count with each copy. A list copied while its channel was suspended, or whose channel suspended since, reads guest memory instead. Lists submitted and run without a wait in between keep the copy. EDEN_NX2_PB_SNAPSHOT=0 still disables it altogether. Assisted-by: Claude Sonnet 5.5 (first version); Claude Opus 5.5 (bisect, suspension count, testing and commit message)
| * | | nx2: don't stall presents on a current-frame wait the GPU can't finishSssnowyyy33 hours1-22/+43

Mario Kart World's GPU waits on semaphores its CPU releases only after the present returns, so in that state the current fence can't be reached until the present returns, and each such present stalled up to the 4 s deadline. Wait for the current frame by default, but give up after a few ms once a GPU channel was seen suspended on a semaphore acquire and wait for the previous frame instead. EDEN_NX2_FRAMES_AHEAD=1 always waits for the previous frame (with 0f14696044's current-frame wait when the GPU is behind), =0 always for the current one. The scheduler gains a lock-free flag so the present thread can see suspended channels. Assisted-by: Claude Sonnet 5.5 (implementation and commit message)

Reject a request whose end wraps the address space before it is used, for map and unmap alike, with a warning like the existing unknown-memory check. Also compare by subtraction in the region lookups here and in Nx2SparseTile and Nx2BackSparse, so none of them depends on the sum. Assisted-by: Claude Sonnet 5.5 (implementation and commit message)
* | | network: fix room host LAN Play and room socket review issuescirakg30 hours1-20/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The room host and room moderators are in the Moderator state, not Joined, so the airplane mode override for joined rooms did not apply to them and LAN Play still returned them to the menu. Accept both states. Share the room address override between the NIFM profile and IP config calls so they cannot drift apart. recv() on a room TCP socket now waited for the receive timeout, because Recv goes through RecvFrom. Room TCP sockets have no peer, so keep the previous immediate end-of-stream result when nothing is queued. Close() now drops queued packets and wakes a blocked recv, which then fails with EBADF. The socket state that the room thread reads when it queues a packet is now guarded by the packet mutex. Assisted-by: Claude Opus 5.5 (investigation and implementation)
* | | nifm: treat a joined room as the LAN for local network gamescirakg31 hours1-3/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | LAN Play through public lobby rooms failed in two ways. With airplane mode on (the default), IRequest::GetResult rejected the game's network request. Mario Kart World then opened the net-connect applet and returned to the main menu instead of the LAN browser. A joined room is the emulated network: its sockets only reach room members. Count it as an available network for GetResult and IsAnyInternetRequestAccepted. With airplane mode off, players could open the browser but never saw each other. Room fake IPs are spread over 192.168.0.0/16, and some room servers give members different /24s. NIFM reported the host adapter's /24 mask with the fake IP, so the games treated each other as off-subnet. Report 255.255.0.0 in a room instead.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Connect slept for a second while holding packet_mutex, so the host's SyncNetwork reply could not be handled until Connect had already returned success in StationOpened. Players could see each other's group and enter it, but never actually met. Wait on a condition variable instead, accept the reply only from the selected host and session, and fail after five seconds. Check packet sizes and senders, stop duplicate joins from taking another station, and seed session IDs so separate networks don't share one. The SDL frontend never called Network::Init, so its multiplayer option could not join a room. Initialize and shut down networking around the core.

The pool memory is process memory (114) that no GPU mapping covered, so the blit read zeros and the movies were black. For decoder images, 426 now maps the image at its own address for the GPU unless a mapping already covers it, and replies with the address, the last byte's address and the image descriptor as our Eden tree does. 427 drops the mapping after the last unmap, as do 430 and 112. Images the client reads on the GPU are written as block-linear RGBA, and the GPU caches are invalidated after each frame. NV12 images and images read with 961 keep the pitch-linear layout.

Key these ranges by (ASID, CPU address, size) and count references. The first address space allocates the range, the last release frees it, and a closed session's entries are dropped so a reused ASID can't inherit them.

Answer 3, 21 and 29 with the same empty success, logging each once. Assisted-by: Claude Sonnet 5.5 (code) (cherry picked from commit 0b7b562898bba137934420b366e3980476ee221f)
* | | nx2: execute command lists as submittedkraibse2 days1-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the present waiting for the previous frame's fence, the game refills command memory it already submitted while the GPU thread is still running that frame, so some frames rendered into the wrong image. Copy each entry's words at submit and execute the copy. Resumed entries and ranges the GPU has newer words for still read memory. EDEN_NX2_PB_SNAPSHOT=0 executes from memory. Ported from Wael3rd/Eglantine-MKW (bd3119a86f). Assisted-by: Claude Sonnet 5.5 (porting the fix) (cherry picked from commit 408bb84d06ae0729697ef9bed2c2ba76ce6dff42)
* | | nx2: leave unwritten sparse blocks without memory when they get zerosTakoroka2 days1-2/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Title 1 clears about 1 GB of its sparse regions at boot through the GPU memory manager. Every block the clear touched got 4 MiB of guest memory, which the clear itself then committed on the host, and counted as written, so the texture cache gave the images over it device memory too. A block nobody wrote reads zero already: when the part of a write that lands on it is all zero, leave it as it is. (cherry picked from commit 0d7ff63fd1a373cecff6ba91022c9027e801e53f)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every call to an auto-stubbed command wrote a Critical report, and Critical flushes the log file. Mario Kart World polls nx2:camera 29 about 47 times a second, so the log flushed that often for the whole session. Each (service, command) pair is reported once; repeats answer success silently.

| * | | | nx2: read command lists the GPU wrote from the GPU's copyTakoroka4 days1-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mario Kart World runs small command lists (20-byte entries) that its culling dispatches fill in each frame. Accurate GPU mode reads every command list through the caches; Fast mode reads guest memory directly (on the split's front thread too), where those entries were still the words of an older frame, so the draws behind them were left out: the trees around the courses vanished in Fast mode only. The buffer cache now also marks the device pages the GPU writes (shader stores, copies of GPU-written data) in a bitmap the split's front can read. A command list on such a page waits for the back to run what was queued before it and is flushed when its words are still only in host buffers. In a race that is ~5% of command lists (13,500 a second of 262,000) and ~400 flushes a second.

So the clears themselves made every page of a game's heap resident: Mario Kart World (12 GB layout) had a 12.5 GB working set 20 s after boot. HostMemory keeps two bits per 64 KiB of backing: used (handed out by the kernel at least once) and dirty (may hold data). Pages returned to the kernel mark their granules dirty, and a zero clear only touches dirty granules; a granule cleared in full is clean again. A new kernel on the same memory marks everything a previous one used dirty, so leaked processes can't leak data into the next game. KMemoryManager's optimized-process fill and KSharedMemory's clear go through the same path. Mario Kart World, title screen and attract demo, 180 s: working set 20 s in 4.7-6.4 GB instead of 12.5 GB, peak 14-17.6 GB instead of 20.1 GB.

Crop to the given size; the handheld 1920x1080 limit still applies, and Mario Kart World's docked crop stays only for presents that give none.
