* SeaBIOS and palo: muldi3 and divdi3 (from libgcc.a) trashes fr22-fr25 because of xmpyu instruction. Doesn't seem to have negative effect, but those registers should better be saved/restored in pdc_entry() and iodc_entry(), or libgcc should be fixed to not use floating point instructions.
 +

 +
* STARTED: convert old-style rtc driver drivers/input/misc/hp_sdc_rtc.c to new RTC model, remove the procfs and miscdevice interfaces first and replace the ioctl with a struct rtc_class_ops. Arnd Bergmann can review those patches, but Alexandre and Alessandro are the ones who would merge them once the driver is moved to drivers/rtc. (Mail from Arnd Bergmann, 28.04.2016) - see https://patchwork.kernel.org/patch/10701397/

 +
* '''QEMU Full-system emulation'''
 +
** Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> offers to do contract work for QEMU through his company.
 +
** Fix migration of VMs (noticed by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>):  Boot a qcow2 image in QEMU using the GTK, Wait a random time anywhere between 5-20s, Pause the VM, Switch to the "monitor" tab, Run "savevm foo" to save the current VM state as "foo", Type "quit" to exit QEMU, Add "-loadvm foo" to your QEMU command line and launch QEMU, Unpause the VM
 +
** Check "HPPA support for IGNITE-UX install discs" for HP Logic Analyzer 16700A (Mail from Keith Monahan <keith@techtravels.org> Sept 2020)
 +
** STARTED: Finish LASI and 82596 NIC for QEMU -> https://github.com/hdeller/qemu-hppa/commits/lasi
 +
*** ncr53c710 driver from amiga: https://github.com/tonioni/WinUAE/blob/master/qemuvga/lsi53c710.cpp
 +
* '''QEMU User-mode emulation'''
 +
** Implement io_submit() syscalls, probably not possible. Check why raft package testcases which fail
 +
** check why qgis, plasma-framework,  kio-extras and fcitx5-chinese-addons fail to build with "Illegal instruction" error (https://buildd.debian.org/status/fetch.php?pkg=qgis&arch=hppa&ver=3.22.4%2Bdfsg-3&stamp=1645691873&raw=0)
 +
** qemu and executable stack: The following error occurred on pacific in mlton build: /usr/lib/mlton/mlton-compile: error while loading shared libraries: libm.so.6: cannot enable executable stack as shared object requires: Invalid argument
 +
** More exec stack errors: openssh, lnav
 +
** It looks like haskell packages still fail on qemu (e.g., haskell-swish).
 +
* '''JAVA'''
 +
** Finish OpenJDK, see patch and mail from Adrian Glaubitz 05.02.2021.
 +
** IMPORTANT: fix OpenJDK - fixes required in zeroport (stack grows up!).
 +
* '''Rust language''' (STARTED: https://github.com/rust-lang/libc/compare/master...hdeller:libc:hppa-devel2)
 +
**From Adrian Glaubitz (9/29/2021): The Rust project merged a change [1] that allows rustc to use GCC instead of LLVM as codegen backend for generating machine code through libgccjit. This means that we are in principal able now to build Rust code for all the architectures that GCC support but LLVM doesn't, which includes hppa. Please see this [2] and this [3] comment to see how to get started with cross-building the Rust compiler for a new target using libgccjit. We will have to add these new architectures to the libc crate first, see an example PR for that here [4]. Since I can't work on all these targets myself, I wanted to ask you to help me and get the support for hppa added to libc and rustc where necessary.

 +
* '''gcc compiler'''
 +
** _mcount can be optimized (smaller) by not subtracting offset)
 +
** check if we can use -fentry from gcc for _mcount optimization
 +
** put PLABELS into read-only section (gcc function pa_reloc_rw_mask() needs modification, see "section mismatches" mails, 11.09.2017)
 +
** gcc: Add _builtin_thread_pointer() and _builtin_set_thread_pointer(), e.g.: https://gcc.gnu.org/ml/gcc-patches/2012-07/msg00428.html  for glibc: ports/sysdeps/hppa/nptl/tls.h __set_cr27()
 +
** STARTED: why is GNU AS so slow, e.g. when building freeorion, quantlib-swig or yade packages, testcases: openturns
 +
*** http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=787192
 +
*** https://sourceware.org/bugzilla/show_bug.cgi?id=18427
 +
** provide libphobos packages - gcc-defaults - http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=763103,  Work by Dave: https://gcc.gnu.org/ml/gcc-testresults/2018-11/msg03460.html
 +
** gcc -> join 32- and 64bit compiler, make "-m64" work, get rid of hppa64-linux-gnu-gcc
 +
* '''64-bit userspace support (from Dave Anglin, Nick Hudson)'''
 +
** 64-bit userspace, [[Binutils]] 64-bit binutils needs to be fixed to get multiple stub section support.
 +
** glibc port (hppa64 can use the generic thread code)
 +
** 64-bit support in gcc is probably pretty good as 64-bit HP-UX works fine.
 +
** gdb could be a problem due to a lack of a maintainer.

* debian parisc perl bug (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=721537) shows that mmap on parisc linux is horribly inefficient.  We allocate huge maps for small files. This should be improved. Mailthread: " parisc mmap: private file maps" ,http://www.spinics.net/lists/linux-parisc/msg05083.html or  https://rt.perl.org/Public/Bug/Display.html?id=119567 https://rt.perl.org/Public/Bug/Display.html?id=119567
* send patches to remove UP from debian kernels, see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=721191
+
* kernel work
* gdb crashes Kernel - http://permalink.gmane.org/gmane.linux.ports.parisc/5406
+
** ALPHA processor port:
* glib2.0 atomic bug: Dave: I see the problem building various packages -- apt is is one. It occurs when multiple dot processes are started by graph when package documentation is being generated.  The number of dot processes spawned depends on the number of processors on the build system.  However, the faults occur even on a UP system. I debugged one of these segvs enough to see that the problem occurred in a glib2.0 library.  It's using the GCC "sync" interface.

*** New one: https://patchwork.kernel.org/patch/10141217/ (alpha: fix crash if pthread_create races with signal delivery)
* More signals? > Can we change _NSIG to 69 so there are 32 RT signals as on other arches? It looks like it needs to be a power of 2MIPS uses 128.  
+
*** Kernel patches: http://marc.info/?t=140610652200001&r=1&w=2, The proposed fix is in: http://marc.info/?t=140675670100010&r=1&w=2, http://marc.info/?t=142327510200001&r=1&w=2,

*** alpha qemu-user bug: https://gitlab.com/qemu-project/qemu/-/issues/494
* currently planned features for 3.13 / 3.14:

** 3.14 partly: return ((unsigned long) mapping >> 7) & ((SHMLBA >> PAGE_SHIFT) - 1); in arch/parisc/kernel/sys_parisc.c
** better implementation to get stack pointer (in return_address(), in stack checker in irq.c, ...)
+
* How to upgrade libgcc:
** physically broken memory in Dave's machine - utilize PDT (http://ftp.parisc-linux.org/docs/arch/pdc20-v1.1-Ch4-pdc.pdf (page #46)) - https://patchwork.kernel.org/patch/2541561/

* Kernel: still missing Linux kernel development (no patches available yet):
+
** implement .con_font_set (consw) in sticon.c (to be able to change fonts at runtime)
+
** Implement CONFIG_DEBUG_STACK_USAGE ?
+
** fix wrong _init notation in kernel
+
** NO_IRQ -> should be converted to (0) instead of (-1) -> Helge (check assembly, check in drivers/parisc/*)
+
** implement alternative coding for UP/SMP. See arch/x86/include/asm/alternative.h
+
** check assembly in drivers/parisc/*
+
** use pdc_add_valid() in kern_addr_valid(),  protect against crashable acesses (like for superio-pc-drivers-detection in lp), add pdc_add_valid() to create a probe_kernel_read() implementation.
+
** arch/parisc/kernel/sys_parisc.c -> use SYSCALL_ALIAS() -> maybe
+
** on C8000, report 1 socket with 2 cores.
+
** implement HUGE pages (or even better transparent huge pages)
+
** Review gettimeofday and clock_gettime() implementation, possibly use a light-weight-syscall and rely on cr16 and cpu speed for more accurate timing? similiar to commit http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=18ad51dd342a7eb09dbcd059d0b451b616d4dafc
+
  
* Kernel: Low priority patches needs further work
+
* Kernel: still missing Linux kernel development (no patches available yet or maybe not possible to implement):
** Fix exception table entries to be of type int (32bit), even on 64bit kernel -> saves space. - https://patchwork.kernel.org/patch/3033801/
+
** maybe: optimize flush_dcache_page() implementation like sparc. See Documentation/cachetlb.txt, e.g. used in aio subsystem
** disable FP-register save/restore at kernel entry? - Helge
+
** maybe implement transparent huge pages (due to cache coherency technically only possible on PA8500-PA8700 CPUs, not possible on PA8800-PA8900 CPUs)
 +
** implement BUG() and WARN() with inline assembly so that interrupt happens in delay branch of "or,<> %r0,cond,%r0". Probably not possible, because gcc will report "control reaches end of non-void function" warnings/errors.
 +
** disable FP-register save/restore at kernel entry? - https://patchwork.kernel.org/patch/3975291/
 
** enable 16k/64k kernel page sizes (still cacheflushing-issues with SCSI driver, additional work in glibc needed to deal with >4k page size, e.g. ld-loader alignments of data/code segments)
 
** enable 16k/64k kernel page sizes (still cacheflushing-issues with SCSI driver, additional work in glibc needed to deal with >4k page size, e.g. ld-loader alignments of data/code segments)
** Superdome support - can someone test? Should work better now with latest kernels.
+
** Superdome support - can someone test? Should work better now with latest kernels (maybe ask Dennis Clarke <dclarke@blastwave.org>, Jan 2019).
** task_struct/thread_info split -- task_struct should not be visible in entry.S, we need to move some items into thread_info -- this includes pt_regs and maybe some of the flags (ptrace, etc)
+
** Visualize FX support (will probably never happen!)
+
 
+
* Debian packaging work:
+
** Build real debian-installer CD. See: https://wiki.debian.org/Simple-CDD/Howto
+
** DONE: we need a kernel debian package (3.10 based or higher)
+
** ONGOING: debian-ports/parisc repository aka. syning debs to there
+
*** DONE: Helge to contact Aurelien (aurel32) on #debian-glibc on OFTC IRC
+
*** Instructions from Thorsten Glaser - see: http://lists.debian.org/debian-hppa/2013/04/msg00049.html

** gcc -> join 32- and 64bit compiler, make "-m64" work, get rid of hppa64-linux-gnu-gcc
+
** Circular dependency problems with kde packages caused by vlc and ffmpeg (Dave)
 +
*** Solution: Rebuild ffmpeg outside the buildd (as some dependencies have probably been deleted) and upload a +b1 version. Then trigger bin-nmu of phonon package. Finally this resolves then the dependencies of vlc, ffmpeg, phonon, chromaprint, polkit-kde-agent-1, kwrited, kwallet-kf5 and  libkf5notifications-dev...
 +
** Due to very bad performance running multiple copies of dot program (Dave)
 +
*** In vtk6 debian package, adding DOT_NUM_THREADS = 1 helps.
 +
 
 +
* Floating point NaN (see: https://en.wikipedia.org/wiki/NaN)
 +
** PA-RISC uses "mips" NaN format which differs from x86, etc. It should be called PA-RISC format as I think PA was first.  The quiet NaN bit is opposite to than in current IEEE standard.

** PALO - add regular rewind & load to avoid tftp boot timing issues. See mail from Frank Schreiner "PALO issues" (Dec 2018).
 +
** When listing directory contents, resolve and print symlink target file names too, e.g. "vmlinux -> linux-5.12.1-64bit".
 +
** Fix palo deb package to build iplboot natively (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=851792)
 
** Modify (if possible), that palo can read (sequential) tftpbootable-vmlinuxes as well as the current boot-vmlinux images (simplifies build/handling)
 
** Modify (if possible), that palo can read (sequential) tftpbootable-vmlinuxes as well as the current boot-vmlinux images (simplifies build/handling)
** add xz-compression support, maybe move decompression to Linux kernel instead of palo?

Even if that's an ABI change, the patch includes a wrapper to translate the values, so that old binaries will continue to work. There were build issues in aws-crt-python, qemu-user, tor browser and boringssl.

 +
== Considerations between Debian unstable and Debian Jessie release ==
 +
Jessie was not stable on SMP machines, particularly those with PA8800/PA8900 processors.
 +
It's recommended to use kernel 4.4.15 or later.
 +
The current default gcc for unstable is gcc 5.4. Most hppa fixes have been back ported to 4.9 but not all.
 +
It shouldn't hurt to use binutils from unstable.
 +
Debian glibc 2.23 is best. Most old packages should still work although there maybe inequivalent aliasing issues
 +
which are relevant on PA8800. There's also a nasty issue with gmon_start being in every shared library in Jessie.
 +
This caused a few headaches and potentially breaks applications when it's removed from a library. If you
 +
stick with the glibc in Jessie, multithreaded applications may not work as well as they could,
 +
but maybe that's not important.
 +
The kernel update is the most important one.
 +
Since hppa moved to ports, there has been a huge number of bug fixes. System stability is
 +
dramatically improved and I believe more packages are available than ever before. It's better to run unstable
 +
and just be selective about running "apt-get upgrade".

PA-RISC Linux TODO

Status & TODO 2023-06-01

  • Kernel: still missing Linux kernel development (no patches available yet or maybe not possible to implement):
    • maybe: optimize flush_dcache_page() implementation like sparc. See Documentation/cachetlb.txt, e.g. used in aio subsystem
    • maybe implement transparent huge pages (due to cache coherency technically only possible on PA8500-PA8700 CPUs, not possible on PA8800-PA8900 CPUs)
    • implement BUG() and WARN() with inline assembly so that interrupt happens in delay branch of "or,<> %r0,cond,%r0". Probably not possible, because gcc will report "control reaches end of non-void function" warnings/errors.
    • disable FP-register save/restore at kernel entry? - https://patchwork.kernel.org/patch/3975291/
    • enable 16k/64k kernel page sizes (still cacheflushing-issues with SCSI driver, additional work in glibc needed to deal with >4k page size, e.g. ld-loader alignments of data/code segments)
    • Superdome support - can someone test? Should work better now with latest kernels (maybe ask Dennis Clarke <dclarke@blastwave.org>, Jan 2019).
  • Floating point NaN (see: https://en.wikipedia.org/wiki/NaN)
    • PA-RISC uses "mips" NaN format which differs from x86, etc. It should be called PA-RISC format as I think PA was first. The quiet NaN bit is opposite to than in current IEEE standard.
    • Debian packages with NaN issues: libime, capnproto
  • palo (PA-RISC Boot Loader):
    • PALO - add regular rewind & load to avoid tftp boot timing issues. See mail from Frank Schreiner "PALO issues" (Dec 2018).
    • When listing directory contents, resolve and print symlink target file names too, e.g. "vmlinux -> linux-5.12.1-64bit".
    • Fix palo deb package to build iplboot natively (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=851792)
    • Modify (if possible), that palo can read (sequential) tftpbootable-vmlinuxes as well as the current boot-vmlinux images (simplifies build/handling)

ABI breakages (e.g. dropped HP-UX support)

Considerations between Debian unstable and Debian Jessie release

Jessie was not stable on SMP machines, particularly those with PA8800/PA8900 processors. It's recommended to use kernel 4.4.15 or later. The current default gcc for unstable is gcc 5.4. Most hppa fixes have been back ported to 4.9 but not all. It shouldn't hurt to use binutils from unstable. Debian glibc 2.23 is best. Most old packages should still work although there maybe inequivalent aliasing issues which are relevant on PA8800. There's also a nasty issue with gmon_start being in every shared library in Jessie. This caused a few headaches and potentially breaks applications when it's removed from a library. If you stick with the glibc in Jessie, multithreaded applications may not work as well as they could, but maybe that's not important. The kernel update is the most important one. Since hppa moved to ports, there has been a huge number of bug fixes. System stability is dramatically improved and I believe more packages are available than ever before. It's better to run unstable and just be selective about running "apt-get upgrade". (by Dave Anglin)
