 # Changelog
+## 1.2.5
+ Support was added for 13.2.0.
+ A number of minor issues were fixed and improvements were made, including:
+  + A bug was fixed that caused `mesosphère` to underreport the total memory size by 8MB for certain games which use newer system-resource-size memory management.
+    + This caused FIFA 19 to crash, and possibly other issues.
+  + Memory management changes were made to `sm` that save 0x5000 of memory.
+  + A microoptimization was made to the way `mesosphère` manages updating the debug register for hardware single-step support.
+  + Support was fixed for enabling `usb!usb30_force_enabled` on 13.0.0+.
+  + The work-in-progress unit testing framework was updated to use doctest instead of catch2.
+ General system stability improvements to enhance the user's experience.
+## 1.2.4
+ Changes were made to the way fs.mitm builds images when providing a layeredfs romfs.
+  + Cache management (to avoid unnecessary rebuild) was revised, to add a grace period of ~500ms-1s between process closing romfs image and ams.mitm needing to rebuild if romfs is re-opened.
+    + This makes our cache much more effective, previously we were re-building romfs several times.
+  + RomFS image ownership was overhauled, with a new reference-counting implementation added (used to implement the above grace period).
+    + Certain games (e.g. Puyo Puyo Tetris 2, probably others) were sensitive to this timing, and could use access patterns which would trigger creation of romfs image while previous romfs image was in the middle of destructor.
+    + This could cause a fatal error, because the destructor for the old image could run simultaneously with building the new image.
+  + This also provides a speedup versus the 1.2.3 code, with Animal Crossing now taking ~8 fewer seconds to get past the Nintendo Switch logo.
+ General system stability improvements to enhance the user's experience.
+## 1.2.3
+ Because ams.TMA is taking longer to develop than expected, experimental support for Atmosphère's gdbstub as a standalone is now available.
+  + To enable it, set `atmosphere!enable_standalone_gdbstub` = u8!0x1 in system_settings.ini.
+    + The standalone also requires `atmosphere!enable_htc` = u8!0x0, but this should be the case for everyone since ams.TMA isn't actually usable yet.
+  + Once enabled, open the devkitPro provided-gdb (`aarch64-none-elf-gdb` for 64-bit or `arm-none-eabi-gdb` for 32-bit).
+    + The standalone stub exposes itself on port 22225 -- so the command to connect is `target extended-remote <ip address>:22225`.
+    + Type `info os processes` to get a list of process IDs that can be attached to.
+      + The stub should work on both system programs, games, and homebrew -- but please note that debugging certain processes (like sockets) can cause hang due to the stub using them itself.
+  + Software break-points, hardware break-points, hardware watch-points, and hardware single-step are all supported/implemented.
+  + The following monitor commands are currently supported:
+    + `monitor get info`: Get process info, address space layout, and information on modules.
+    + `monitor get mappings`: Get all memory mappings.
+    + `monitor get mapping <addr>`: Get the memory mapping for a specific address.
+    + `monitor wait application`: Causes the stub to wait for an application to be launched. The next application will be started suspended.
+      + User is expected to send `attach <pid>` after launching, which will cause attach-on-first-instruction. Failure to attach may cause system instability, this probably needs work.
+  + **Please Note**: The GDBstub is new and may have bugs/need work. If you find issues, please report them to SciresM#0524 -- all help finding/fixing bugs is appreciated, here.
+  + Generally speaking, if you would like to report information about fixes needed/discuss development of the gdbstub, join ReSwitched's #dev-support channel.
+ Changes were made to the way fs.mitm builds images when providing a layeredfs romfs.
+  + Animal Crossing's 2.0.0 update contains >99000 files, and has tables so big that we ran out of memory even after the optimizations made in 0.10.5.
+    + Previously, we used fixed-sized 0x40000 work buffers for file/directory tables and simultaneously built hash/content tables in one loop over files/directories.
+    + We now iterate over the file/directory tables multiple times, first once to determine the hash table indices, then repeatedly to build hash tables, then once to build content tables.
+    + We also now allow smaller-than-0x40000 work buffers, trying half-as-big buffers until allocation succeeds (or work buffer would be <0x4000, which is a safeguard against truly horrible performance).
+  + There is a slight speed penalty to these changes, but it's on the order of seconds for the worst case (Animal Crossing) and trivial for most games with reasonable tables.
+  + If you encounter a game that exhausts ams.mitm's memory (crashing it) when loading layeredfs mods, please contact `SciresM#0524`.
+    + It's really hard to imagine any game being worse than Animal Crossing, but if it happens again I will drop everything to fix it as usual.
+ `creport` now attempts to parse symbol tables if present.
+  + If a game executable has a symbol for a given address, the function-relative-offset will now be printed after the module-relative-offset.
+ General system stability improvements to enhance the user's experience.
+## 1.2.2
+ A number of fixes were made to Atmosphère's implementation of the new "sprofile" service added in 13.0.0.
+  + Nintendo is finally transmitting data over the internet to certain consoles, which has allowed for validating our service implementation.
+    + Unfortunately, there were several problems, and if your console began trying to use the new services atmosphere would show a fatal error with code 0xCAF6 (sprofile::ResultInvalidState()).
+  + With actual test data in hand, a test program was written and it was verified that our implementation can successfully import/access profile data now.
+    + Hopefully there are no more issues, and I sincerely apologize for anyone who got an 0xCAF6 fatal due to this.
+ A number of minor improvements were made to `mesosphère`, including:
+  + KThread::GetContextForSchedulerLoop was implemented in assembly (using static assertions to verify offset-of-context-in-struct is correct).
+    + This saves an unnecessary function call in the middle of the scheduler hot loop, replacing it with an addition instruction, which should improve microperformance.
+  + Mesosphere's hardware maintenance instructions were audited via a script and now directly match Nintendo's kernels.
+    + Notably, this inserts a missing instruction synchronization barrier when validating that slab heaps may be constructed.
+    + This missing ISB could cause an abort on certain (see: particularly sensitive) hardware on boot if the relevant codepath was speculatively executed (it normally only executes on game launch...)
+  + The SVC handlers for performing light IPC (normally unused) from 32-bit process were fixed in Mesosphere.
+  + A bug was fixed that would cause the register x27 to be overwritten with the contents of x26 when returning from a user exception handler.
+  + A bug was fixed that would cause the kernel to use the userland stack pointer instead of the kernel stack pointer while generating an error report for a kernel abort.
+ General system stability improvements to enhance the user's experience.
+## 1.2.1
+ Support was implemented for 13.1.0.
+  + `mesosphère` was updated to reflect the kernel behavioral changes made in 13.1.0.
+    + KScheduler now issues a data memory barrier when unlocking the scheduler lock and when early-returning due to top-thread-is-current during scheduling.
+  + `erpt` was  updated to reflect the latest official behaviors.
+    + The new service added in 13.0.0 ("sprofile") was revised, and the data formats it expects was changed.
+      + This still appears to be (possibly(?)) untestable due to data not being transmitted yet, but I have greater confidence things will go smoothly than I did when 1.1.0 released.
+ A number of improvements were made to `mesosphère`, including:
+  + A build target was created to build targeting the qemu `virt` board.
+    + This facilitates writing unit tests for the kernel (and other atmosphere components) and running them under PC.
+      + **Please Note**: Official system software will not work at all under this, and the Atmosphère project has zero interest in attempting to run official software of any kind. This is unit testing machinery, and explicitly not more than that.
+    + This should hopefully allow us to have greater confidence that all of atmosphere's components work the way they're theoretically supposed to in the future.
+    + **Please Note**: If you are a developer who is familiar with the Horizon operating system (or capable of becoming familiar), I would greatly appreciate help writing tests and improving the testing framework.
+      + Please contact `SciresM#0524` if you are capable and interested.
+        + Really, if you are actually a developer who would like to help me get this off the ground, I would deeply appreciate it.
+        + That said, if you are not a developer but want to be one, this probably isn't the best opportunity; I expect it to be highly technical.
+          + Consider the ReSwitched discord's #hack-n-all channel for your educational purposes.
+      + We are (at least for now) using [catch2](https://github.com/catchorg/Catch2) for unit tests.
+  + Almost all virtual calls in the kernel are now resolved statically.
+    + This eliminates substantial virtual call overhead, and should lead to improved kernel microperformance in pretty much every function.
+  + The remaining red black tree find operations which weren't using the optimized "find key" variant are now using the optimized version.
+  + Custom assembly was written to improve tick-to-timespan conversion.
+    + This works around gcc emitting suboptimal assembly at -Os (it emits good assembly at -O3, clang is fine at both -O3 and -Os).
+  + KThread and KSession structures were updated to optimize member layout, saving 0x10 bytes per KThread/KSession object.
+  + Rather than unnecessarily zero-ing all data in kernel objects only to overwrite members later, we now only initialize the members we need to in kernel object constructors.
+    + This is what Nintendo was doing already.
+  + A set of custom optimized atomic primitives were implemented and are used in place of std::atomic<>
+    + This works around a gcc bug which downgrades specified memory order to seq_cst, and introduces clrex in places where it is appropriate.
+    + This should strictly improve microperformance of many system calls.
+  + An compile-time toggleable extension was added to support 40-bit physical addresses in MapRange capabilities (using currently reserved bits).
+  + A number of minor bugs were fixed, including:
+    + Initial cache management now better reflects official behavior.
+      + This fixes an issue that caused certain hardware with cache sensitivity to produce cryptic kernel panics during boot.
+    + Incorrect logic when checking thread priority capabilities was fixed to reflect official behavior.
+    + The scheduler was updated to reflect latest official behavior, and a number of minor bugs involving clz/ctz were fixed.
+    + Accesses to the processes local region were fixed to properly use kernel linear region, not userland pointers.
+    + The cache SVCs exposed for 32-bit processes now better reflect official core mask request semantics.
+    + A bug was fixed that could cause a kernel panic if SvcArbitrateLock was called on a thread with exactly one reference in the middle of handling a user-mode exception.
+ General system stability improvements to enhance the user's experience.
 ## 1.2.0
 + `boot` was updated to reflect the latest official behavior for display/battery management.
  + This should fix any issues that might result from running older releases on the OLED model, if you're somehow in a position to do so.

Léo Lam	496adb0018	Minor header fixes to reduce parsing issues with Clang (#1700 ) * Work around Clang's incomplete C++20 support for omitting typename * vapours: fix Clang error about missing return in constexpr function * stratosphere: fix call to non-constexpr strlen in constexpr function strlen being constexpr is a non-compliant GCC extension; Clang explicitly rejects it: https://reviews.llvm.org/D23692 * stratosphere: add a bunch of missing override specifiers * stratosphere: work around Clang consteval bug Minimal example: https://godbolt.org/z/MoM64v93M The issue seems to be that Clang does not consider f(x) to be a constant expression if x comes from a template argument that isn't a non-type auto template argument (???) We can work around this by relaxing GetMessageHeaderForCheck (by using constexpr instead of consteval). This produces no functional changes because the result of GetMessageHeaderForCheck() is assigned to a constexpr variable, so the result is guaranteed to be computed at compile-time. * stratosphere: fix missing require clauses in definitions GCC not requiring the require clauses to be repeated for member definitions is actually a compiler bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96830 Clang rejects declarations with missing require clauses. * Fix ALWAYS_INLINE_LAMBDA and parameter list relative order While GCC doesn't seem to care about the position of the always_inline attribute relative to the parameter list, Clang is very picky and requires the attribute to appear after the parameter list (and before a trailing return type) * stratosphere: fix static constexpr member variable with incomplete type GCC accepts this for some reason (because of the lambda?) but Clang correctly rejects this.	2021-11-06 18:19:34 -07:00

Michael Scire	5eabca7f04	ams.mitm: more romfs building space/time tradeoffs. This is needed for Animal Crossing 2.0.0, which has >99000 fucking files. We now do several passes over dir/file tables instead of one pass, doing entire hash tables before we touch dir/file tables. Thus we no longer need to simultaneously allocate hash table and dir/file table space. In addition, we now do repeated passes building a segment of hash tables at a time, when insufficient memory is available. Similar is also now the case for file/dir tables, we try 0x40000 work buffer and divide by 2 until we successfully alloc. We don't allow a work buffer <0x4000, for write/perf reasons. If a game triggers that, let me know I guess. Hard to imagine a worse torture-test for this code than animal crossing.	2021-11-03 23:52:38 -07:00
