aa7d070732 arm uart: Rename getc/putc to getchar/getchar
* Avoid name collisions
* This uart stuff may work better as a class at
  some point, however I didn't want to rock the
  u-boot boat *too* much as I don't have the
  hardware to test.

cc586f1655 x86: AMD C1E with no ARAT(Always Running APIC Timer) idle support
AMD C1E is a BIOS controlled C3 state. Certain processors families
may cut off TSC and the lapic timer when it is in a deep C state,
including C1E state, thus the cpu can't be waken up and system will hang.

This patch firstly adds the support of idle selection during boot. Then
it implements amdc1e_noarat_idle() routine which checks the MSR which
contains the C1eOnCmpHalt (bit 28) and SmiOnCmpHalt (bit 27)  before
executing the halt instruction, then clear them once set.

However intel C1E doesn't has such problem. AMD C1E is a BIOS controlled
C3 state. The difference between C1E and C3 is that transition into C1E
is not initiated by the operating system. System will enter C1E state
automatically when both cores enters C1 state. As for intel C1E, it
means "reduce CPU voltage before entering corresponding Cx-state".

This patch may fix #8111, #3999, #7562, #7940 and #8060

Copied from the description of #3999:
>but for some reason I hit the power button instead of the reset one. And
>the boot continued!!
The reason is CPUs are waken up once power button is hit.

599f30f93d Fix building the m68k kernel
* Restructured the vm support code to align with the changes done to other archs.
* Not completely finished, but the kernel loads and panics. I had this sitting on the disk anyway.
* Only support 040 for now, 030 will need to be added back.
* This commit is dedicated to Jack Tramiel who passed away away last sunday:

8dd1e875c1 kernel: Fix FPU SSE + MMX instruction usage.
* Rename init_sse to init_fpu and handle FPU setup.
* Stop trying to set up FPU before VM init.
  We tried to set up the FPU before VM init, then
  set it up again after VM init with SSE extensions,
  this caused SSE and MMX applications to crash.
* Be more logical in FPU setup by detecting CPU flag prior
  to enabling FPU. (it's unlikely Haiku will run on
  a processor without a fpu... but lets be consistant)
* SSE2 gcc code now runs (faster even) without GPF
* tqh confirms his previously crashing mmx code now works
* The non-SSE FPU enable after VM init needs tested!

5cbe06f482 Allow replacing the object cache with the guarded heap.
This allows to use the debug features of the guarded heap also on
allocations made through the object cache API. This is obivously
horrible for performance and uses up huge amounts of memory, so the
initial and grow sizes are adjusted accordingly.

Note that this is a rather simple hack, using the object_cache pointer
to transport the allocation size. The alignment is neglected completely.

7418dbd908 Introduce debug page wise kernel area protection functions.
This adds a pair of functions vm_prepare_kernel_area_debug_protection()
and vm_set_kernel_area_debug_protection() to set a kernel area up for
page wise protection and to actually protect individual pages
respectively.

It was already possible to read and write protect full areas via area
protection flags and not mapping any actual pages. For areas that
actually have mapped pages this doesn't work however as no fault, at
which the permissions could be checked, is generated on access.

These new functions use the debug helpers of the translation map to mark
individual pages as non-present without unmapping them. This allows them
to be "protected", i.e. causing a fault on read and write access. As they
aren't actually unmapped they can later be marked present again.

Note that these are debug helpers and have quite a few restrictions as
described in the comment above the function and is only useful for some
very specific and constrained use cases.

643cf35ee8 Add debug helper functions to mark pages present.
They can be used to mark pages as present/non-present without actually
unmapping them. Marking pages as non-present causes every access to
fault. We can use that for debugging as it allows us to "read protect"
individual kernel pages.

79f0056002 Fix virtual 8086 mode to properly account for TLS.
* The vm86 code or the code running in virtual 8086 mode may clobber the
  %fs register that we use for the CPU dependent thread local storage
  (TLS). Previously the vm86 code would simply restore %fs on exit, but
  this doesn't always work. If the thread got unscheduled while running
  in virtual 8086 mode and was then rescheduled on a different CPU, the
  vm86 exit code would restore the %fs register with the TLS value of
  the old CPU, causing anything using TLS in userland to crash later on.
  Instead we skip the %fs register restore on exit (as do the other
  interrupt return functions) and explicitly update the potentially
  clobbered %fs by calling x86_set_tls_context(). This will repopulate
  the %fs register with the TLS value for the right CPU. Fixes #8068.

* Made the static set_tls_context() into x86_set_tls_context() and made
  it available to others to faciliate the above.

* Sync the vm86 specific interrupt code with the changes from hrev23370,
  using the iframe pop macro to properly return. Previously what was
  pushed in int_bottom wasn't poped on return.

* Account for the time update macro resetting the in_kernel flag and
  reset it to 1, as we aren't actually returning to userland. This
  didn't cause any harm though as only the time tracking is using that
  flag so far.

* Some minor cleanup.

54e721afeb Add support for bind-mounting directories
* Add support function vfs_get_mount_point(), so a file system can get
  its own mount point (i.e. the node it covers). Re-added
  fs_mount::covers_vnode for that purpose -- the root node isn't know to
  the VFS before the mount() hook returns.
* Add function vfs_bind_mount_directory() which bind-mounts a directory
  to another. The Vnode::covers/covered_by mechanism is used, so this
  isn't true bind-mounting, but sufficient for what we need ATM and
  cheaper as well. The vnodes connected thus aren't tracked yet, which
  is needed for undoing the connection when unmounting.
* get_vnode_name(): Don't use dir_read() to read the directory. Since we
  have already resolved vnode to the covered vnode, we don't want the
  dirents to be "fixed" to refer to the covering nodes. Such a vnode
  simply wouldn't be found.

* Adjust all code that deals with transitions between mount points and
  volume root vnodes to generally support covered/covering vnodes.

* Refactor memory region code to be aware of 64-bit OF addresses.
  As-is the boot loader wouldn't start on G5 systems because
  OpenFirmware memory base addresses are stored as two 32-bit
  unsigned int 'cells' vs one 32-bit unsigned int 'cell' on G3/G4.
  I removed the static struct and replaced it with a template
  and pass uint32 or uint64 depending on the address cell size.
  Thanks for the idea DeadYak!

d61a8548f9 Add support for bind-mounting directories
* Add support function vfs_get_mount_point(), so a file system can get
  its own mount point (i.e. the node it covers). Re-added
  fs_mount::covers_vnode for that purpose -- the root node isn't know to
  the VFS before the mount() hook returns.
* Add function vfs_bind_mount_directory() which bind-mounts a directory
  to another. The Vnode::covers/covered_by mechanism is used, so this
  isn't true bind-mounting, but sufficient for what we need ATM and
  cheaper as well. The vnodes connected thus aren't tracked yet, which
  is needed for undoing the connection when unmounting.
* get_vnode_name(): Don't use dir_read() to read the directory. Since we
  have already resolved vnode to the covered vnode, we don't want the
  dirents to be "fixed" to refer to the covering nodes. Such a vnode
  simply wouldn't be found.

2e21fc5436 Generalize use of Vnode::covered_by/covers
* Introduce Vnode flags for covered and covering. Can be used as a quick
  check when one doesn't already hold sVnodeLock.
* Rename resolve_mount_point_to_volume_root() to
  resolve_vnode_to_covering_vnode().
* Adjust all code that deals with transitions between mount points and
  volume root vnodes to generally support covered/covering vnodes.

    message.

cbc85916fb Add boot loader packagefs support
* Add pread().
* Add Node::ReadLink() to read a symbolic link path.
* Add Directory::LookupDontTraverse() and make Lookup() non-abstract.
  Lookup() is implemented via LookupDontTraverse() and Node::ReadLink().
* Adjust all FS implementations accordingly.
* Add a packagefs implementation. Unlike other FS implementations it
  isn't a pseudo-module, but provides a function to explicitly mount a
  package file (packagefs_mount_file()).
* Finish BootVolume::SetTo() implementation, mounting the package file
  and replacing fSystemDirectory.

Now the boot loader can load the kernel and boot modules from a packaged
system. The kernel boots up to the point where the boot volume is
mounted.

d11ea2b5ed Introduce BootVolume abstraction class
BootVolume is initialized from a root directory of a volume. It finds
the system directory, and -- not implemented yet -- mounts the system
package, if the system is packaged, replacing the system directory with
it. Adjusted several functionality (main(), the loader functions,
user_menu()) to use BootVolume instead of the root directory.

  implements the method calling the new module hook.
* _user_uninitialize_partition(): Also let the disk system uninitialize the

This fixes the failure to initialize a disk device with BFS, when it contains a

  that the XSDT exports different pointer widths for its links to other tables
  than the RSDT.

* Changed the semantics of the debugger_module_info::debugger_getchar() hook.
  It is supposed to return immediately now.
* Adjusted usb_keyboard accordingly. Hacked UHCI's debug_process_transfer() to
  achieve that. It does now start, check, or cancel a transfer. Split
  UHCI::ProcessDebugTransfer() into StartDebugTransfer(), and
  CheckDebugTransfer() accordingly, and also added a CancelDebugTransfer().

* read_line(): Also support 0x7f as backspace code. That's what xterm sends.

8837310ce7 * Slightly alter the semantics of the input gathering function to take the
menu item it's associated with rather than an input string. This allows it
  to calculate the position to start the input at, as well as the correct
  line to place it on. The previous solution always put the input at the
  center line, which happened to be the right place by happy coincidence
  unless one also had the menu items for viewing/saving the debug syslog
  present.
* Implement input buffer scrolling, and consequently lift the previous size
  limit on user input (it is now only limited by the size of the passed in
  buffer).
* Implement parsing of the input buffer to allow it to handle comma-separated
  options. Thus, one can now input things like "disable_smp true, serial_debug_output false"
  and it will be handled properly.

aren't otherwise exposed via the safe mode menus. The option can be 
found under the debug options menu, where additional settings can be 
added one at a time with the same syntax used in kernel settings files 
(i.e. disable_acpi on). 

Scrolling of the input buffer is not yet supported (will implement that 
soon), so currently the input is clamped to the size of one line. This 
shouldn't be a problem for our current set of options though.

fb5a1727f4 * Implement interrupt source overrides. We install a relay interrupt handler
at the override entry to trigger the overriden vector so that we don't need
  to configure any additional redirections.
* Also configures the polarity and trigger modes found in the override entry.
* When disabling the legacy PIC, retrieve the enabled interrupts and re-enable
  then in the IO-APIC. This will for example make the ACPI SCI work that is
  installed prior to switching interrupt models. Through the transparent support
  for interrupt source overrides it'll also automatically relay from the old to
  the new vector.

This should make ACPI interrupts work and should support relocating the ISA PIT
from irq 0 to a different global system interrupt (usually 2) so that it can
still work when IO-APICs are in use.

8908aef9c2 * Don't map the IO-APIC within the bootloader. We don't need it to set up SMP
at all and, since there can be multiple IO-APICs, we need to do the
  enumeration again in the kernel anyway. Also only set ioapic_phys the first
  time we encounter an IO-APIC object as it looks cleaner when we arrive at the
  first IO-APIC default address.
* Therefore we don't have to worry about already mapped IO-APICs when
  enumerating them in the kernel.
* Also remove the mapping function that is now not used anymore.
* We still use the ioapic_phys field of the kernel args to determine whether
  there is an IO-APIC at all to avoid needlessly doing the enumeration again.

This fixes multi IO-APIC configurations, because before we would indeed map
the last IO-APIC listed in the MADT, but then in the kernel assumed we mapped
the first one. We'd end up with mapping the last listed IO-APIC twice and the
first IO-APIC never, always programming the last one when we actually targetted
the first one.

a56cbb2afb * When initializing MSI support, don't assume a single 24 entry IO-APIC. Instead
mark the ISA interrupts as unusable and then use ioapic_is_interrupt_available
  to determine if that vector is possibly taken by an IO-APIC. If IO-APICs are
  not used, this will simply always return false, leaving all vectors free for
  MSI use.
* The msi_init() now has to be done after a potential IO-APIC init, so it is now
  done after ioapic_init() instead of inside apic_init().
* Add apic_disable_local_ints() to clear the local ints on the local APIC once
  we are in APIC mode (i.e. the IO-APIC is set up and we don't need the external
  routing anymore).

c917cd6261 * ARM: Major VM work
- This is mostly a copy of the x86 32bit paging method and infrastructure, this was copied for two reasons:
		1) It is the most complete VM arch
		2) The first ARM PAE patches have landed on alkml, so we will have to deal with it in the future as well,
		   and this infrastructure has proven to be ready ;)
	- No protection features, or dirty/accessed tracking yet
	- Lots of #if 0

	but....

	It boots all the way up to init_modules() now, and then dies because of a lack of (ARM) ELF relocation implementation!

	Since at this point the VM can be fully initialised, I'm going to focus on CPU exceptions next, so we can get KDL to trigger
	when it happens, and I can actually debug from there ;)

* x86_handle_debug_exception(): When encountering a syscall single-step, also
  set the THREAD_FLAGS_DEBUG_THREAD thread flag. Otherwise the
  B_THREAD_DEBUG_STOP would be ignored.
* x86 interrupt handling, DISABLE_BREAKPOINTS():
  - Renamed to STOP_USER_DEBUGGING().
  - Now it also call x86_exit_user_debug_at_kernel_entry() when
    THREAD_FLAGS_SINGLE_STEP is set, so that the debug registers are saved.

b7e825d6e7 boot_net: Add TCP support
Modelled after UDP, add limited TCP support to the boot net stack. The socket
works by queuing received packets as well as sent packets that have not yet
been ACK'ed. Some known issues are documented, especially there's only limited
congestion control. I.e., we send immediately and in unlimited quantity, thus
its use should be restricted to local networks, and due to a fixed window size
there is potential for our socket being overrun with data packets before they
are read. Some corner cases like wrapping sequence numbers may cause a timeout.

The TCP implementation is based on Andrew S. Tanenbaum's "Computer Networks",
4th ed., as well as lecture notes from Prof. W. Effelsberg, the relevant RFCs
and Wikipedia. The pseudo-random number Galois LFSR used for the sequence
number was suggested by Endre Varga.

Since the code is unlikely to get much smaller, better merge it now so that
subsequent changes get easier to review. No platform actively uses TCP sockets
yet, and the receiving code has been reviewed for endianness issues and should
terminate okay after verifying the checksum if no sockets are open.
Based on a version tested with custom code (#5240) as well as with iSCSI.
Compile-tested boot_loader_openfirmware, pxehaiku-loader with gcc4 and
haiku_loader with gcc2. Closes ticket #5240.

Changes from #5240 proposed patch:
* Various bug fixes related to queuing, some memory leaks fixed.
* Never bump the sequence number when dequeuing a packet. It's done afterwards.
* Don't bump the sequence number again when resending the queue or ACK'ing.
* Aggressively ACK while waiting for packets.
* Don't queue sent ACK-only packets.
* More trace output, esp. for queue inspection.
* Adapted use of TCP header flags to r38434.

7e965f506d More consolidation of timezone code:
* dropped DaylightSavingTime from real_time_clock code in kernel, it was
  never really being used for what it meant (and just being referred to by
  gettimeofday(), which put a different meaning to it
* adjusted the syscalls get_timezone() & set_timezone() as well as their callers 
  accordingly
* got rid of get_rtc_info() and rtc_info struct in kernel, as it was only
  being referred to by the FAT add-on and that one (like gettimeofday()) put a
  different meaning to tz_minuteswest. Added a comment to FAT's util.c
  showing a possible solution, should the hardcoded GMT timezone pose a problem.
* fixed declaration of gettimeofday() to match POSIX base specs, issue 7
* changed implementation of gettimeofday() to not bother trying to fill struct
  timezone - it was using wrong values before, anyway.

  relevant (and the two corresponding parameters were removed)
* C++-ified and reworked clockconfig to use the info from 'Time settings' 
  to setup the timezone info during boot
* removed invocation of _kern_get_tzfilename() from tzset(), as the syscall
  no longer exists and tzset() is currently broken anyway
* adjusted the Time preflet to use the renamed syscall when getting/setting 
  the RTC info

b944766870 * Moved the vm_page initialization from vm_page.cpp:vm_page_init() to the new
vm_page::Init().
* Made vm_page::wired_count private and added accessor methods.
* Added VMCache::fWiredPagesCount (the number of wired pages the cache
  contains) and accessor methods.
* Made more use of vm_page::IsMapped().
* vm_copy_on_write_area(): Added vm_page_reservation* parameter that can be
  used to request a special handling for wired pages. If given the wired pages
  are replaced by copies and the original pages are moved to the upper cache.
* vm_copy_area():
  - We don't need to do any wired ranges handling, if the source area is a
    B_SHARED_AREA, since we don't touch the area's mappings in this case.
  - We no longer wait for wired ranges of the concerned areas to disappear.
    Instead we use the new vm_copy_on_write_area() feature and just let it
    copy the wired pages. This fixes #6288, an issue introduced with the use
    of user mutexes in libroot: When executing multiple concurrent fork()s all
    but the first one would wait on the fork mutex, which (being a user mutex)
    would wire a page that the vm_copy_area() of the first fork() would wait
    for.

  - Fixed conversion of base/limit to array indexes. sPhysicalPageOffset was not
    taken into account.
  - Takes a physical_address_restrictions instead of base/limit and also
    supports alignment and boundary restrictions, now.
* map_backing_store(), VM[User,Kernel]AddressSpace::InsertArea()/
  ReserveAddressRange() take a virtual_address_restrictions parameter, now. They
  also support an alignment independent from the range size.
* create_area_etc(), vm_create_anonymous_area(): Take
  {virtual,physical}_address_restrictions parameters, now.
* Removed no longer needed B_PHYSICAL_BASE_ADDRESS.
* DMAResources:
  - Fixed potential overflows of uint32 when initializing from device node
    attributes.
  - Fixed bounce buffer creation TODOs: By using create_area_etc() with the
    new restrictions parameters we can directly support physical high address,
    boundary, and alignment.

9623c48284 SMP: remove the tracking of apic id -> cpu id. Don't pass between bootloader and kernel.
Kernel doesn't use it, and it could be regenerated in the kernel if it did need it.

This also unlocks the apic range the bios can use. Previously the apic ids would have
to fit within 0..MAX_CPUS or it'd reject the cpu. Some boxes (mine in particular)
seem to sparsely populate the apic id so that the range is pretty large.

13fa4c845a * Introduced new area creation flag CREATE_AREA_DONT_COMMIT_MEMORY.
map_backing_store() doesn't commit memory when this flag is given.
* Used the new flag vm_copy_area(): We no longer commit memory for read-only
  areas. This prevents read-only mapped files from suddenly requiring memory
  after fork(). Might improve the situation on machines with very little RAM
  a bit.
  We should probably mark writable copies over-committing, since the usual
  case is fork() + exec() where the child normally doesn't need more than a
  few pages until calling exec(). That would significantly reduce the memory
  requirement for jamming the Haiku tree.

  there really is a show stopper in the init process, panicking would be the

* Most VM syscalls check the provided protection against B_USER_AREA_FLAGS
  instead of B_USER_PROTECTION, now. This way they allow for
  B_OVERCOMMITTING_AREA as well.
* _user_map_file(), _user_set_memory_protection(): Check the protection like
  the other syscalls do and use fix_protection() instead of doing that
  manually.

7f987e49d7 Added a rendez-vous variable parameter to smp_trap_non_boot_cpus() and make
boot CPU wait until all other CPUs are ready to wait. This solves a
theoretical problem in main(): The boot CPU could run fully through the early
initialization and reset sCpuRendezvous2 before the other CPUs left
smp_cpu_rendezvous(). It's very unlikely on real hardware that the non-boot
CPUs are so much slower, but it might be a concern in emulation.

b1e06d23ce * The "page_stats" command does now also print the longest contiguous runs of
free respective free and cached pages.
* Removed the unused vm_page_allocate_page_run_no_base().
* vm_page_allocate_page_run() (and allocate_page_run()):
  - Use vm_page_reserve_pages() instead of vm_page_try_reserve_pages(), i.e.
    wait until the reservation succeeds.
  - Now we iterates two times through the pages to find a suitable page run. In
    the first iteration it only looks for free/clear pages, in the second
    iteration it also considers cached pages. This increases the chance of the
    function to succeed, when a lot of caching is going on.
    This reduces the amount of memory required to use the IOCache when booting
    off the anyboot Live CD to around 160 MB in qemu. It also seems to work with
    128 MB, but the syslog indicates that some memory allocations fail, which
    is not exactly inspiring confidence.

  - When the standard memcpy() (with fault handler) fails, fall back to
    vm_debug_copy_page_memory().

33fbe25496 * Add code to allocate and free interrupt vectors for message signaled
interrupts (MSI).
* Add the remaining IDT entries and redirection functions in the interrupt code.
* Make the PIC end_of_interrupt() return a result to indicate whether the vector
  was handled by this PIC. If it isn't we now issue a apic_end_of_interrupt()
  in the assumption of apic local interrupt, MSI or IPI. This also removes
  the need for the gUsingIOAPIC global and doing manual apic_end_of_interrupt()
  calls in the SMP and timer code.
