Userland switch is implemented, as is basic system call support (using
SYSCALL/SYSRET). The system call handler is not yet complete: it doesn't
handle more than 6 arguments, and does not perform all the necessary kernel
entry/exit work (neither does the interrupt handler). However, this is
sufficient for runtime_loader to start and print some debug output.
Since the commpage is at a kernel address, changed 64-bit paging code
to match x86's behaviour of allowing user-accessible mappings to be
created in the kernel portion of the address space. This is also
required by some drivers.
Since this argument may be used to pass pointers, uint32 is not
correct for 64-bit. Effectively no change on 32-bit targets, both
size_t and uint32 are unsigned long there.
- Store whether or not the use of the horizontal scrollbar is desired
on the class itself. If the CLV was set to use the horizontal scrollbar,
and then asked to lay itself out while hidden, it would incorrectly assume
the horizontal scrollbar wasn't in use, and consequently repositioned its
views such that the horizontal scrollbar and outline view overlapped.
Uses the x86 architecture code, made fixes to printf formats and a
couple of 64-bit fixes. Only potentially intrusive change is that I've
changed PCI.h to use uint32 rather than ulong. I don't see any way
this would cause any issues, though.
Currently all debugger commands assume 32-bit pointers when formatting their
output. This means that on x86_64 the output is incorrectly formatted. Fixed
this by adding a B_PRINTF_POINTER_WIDTH definition (16 on 64-bit, 8 on
32-bit), and using this to correctly format the output. Not all commands have
been fixed yet, but all VM, slab, VFS, team, thread and image commands should
be correct.
No major changes to the kernel: just compiled in arch_smp.cpp and fixed the
IDT load in arch_cpu_init_percpu to use the correct limit for x86_64 (uses
sizeof(interrupt_descriptor)). In the boot loader, changed smp_boot_other_cpus
to construct a temporary GDT and get the page directory address from CR3, as
what's in kernel_args will be 64-bit stuff and will not work to switch the
CPUs into 32-bit mode in the trampoline code. Refactored 64-bit kernel entry
code to not use the stack after disabling paging, as the secondary CPUs are
given a 32-bit virtual stack address by the SMP trampoline code which will
no longer work.
A proper page fault handler was required for areas that were not locked
into the kernel address space. This enables the boot process to get
up to the point of trying to find the boot volume.
* Thread creation and switching is working fine, however threads do not yet
get interrupted because I've not implemented hardware interrupt handling
yet (I'll do that next).
* I've made some changes to struct iframe: I've removed the e/r prefixes
from the member names for both 32/64, so now they're just named ip, ax,
bp, etc. This makes it easier to write code that works with both 32/64
without having to deal with different iframe member names.
This has been done by adding typedefs in elf_common.h to the correct ELF
structures for the architecture, and changing all Elf32_* uses to those
types. I don't know whether image loading works as I cannot test it yet,
there may be some 64-bit safety issues around. However, symbol lookup for
the kernel is working correctly.
* Uses 64-bit multiplication, special handling for CPUs clocked < 1 GHz
in system_time_nsecs() not required like on x86.
* Tested against a straight conversion of the x86 version, noticably
faster with a large number of system_time() calls.
* typedef for jmp_buf was using int where it should be long.
* setjmp was clearing the buffer pointer rather than the signal mask before
calling sigsetjmp.
* KDL now works without crashing on x86_64.
* Added empty source files for all the 64-bit paging method code, and a
stub implementation of X86PagingMethod64Bit.
* arch_vm_translation_map.cpp has been modified to use X86PagingMethod64Bit
on x86_64.
* Some things are currently ifndef'd out completely for x86_64 because
they aren't implemented, there's a few other ifdef's to handle x86_64
differences but most of the code works unchanged.
* Renamed some i386_* functions to x86_*.
* Added a temporary method for setting the current thread on x86_64
(a global variable, not SMP safe). This will be changed to be done
via the GS segment but I've not implemented that yet.
For now I've just put all the stub functions that are needed to link the
kernel into a file called stubs.cpp. I've not yet moved across the interrupt
handling code or the ELF64 relocation code to the x86 directory. Once those
have been moved I can get rid of the x86_64 headers/source directories.
Not many changes seeing as there's not much x86_64 stuff done yet. Small
differences are handled with ifdefs, large differences (descriptors.h,
struct iframe) have separate headers under arch/x86/32 and arch/x86/64.
The setup procedure is fairly simple: create a 64-bit GDT and 64-bit page
tables that include all kernel mappings from the 32-bit address space, but at
the correct 64-bit address, then go through kernel_args and changes all virtual
addresses to 64-bit addresses, and finally switch to long mode and jump to the
kernel.
Introduce a function to generate the string representation of a bitrate
(kbps, mbps, gbps, etc..)
* Factor out the code from MediaPlayer InfoWindow
* Allow different bases (/1000 or /1024)
* platform_allocate_elf_region() is removed, it is implemented in platform-
independent code now (ELF*Class::AllocateRegion). For ELF64 it is now
assumed that 64-bit addresses are mapped in the loader's 32-bit address space
as (address - KERNEL_BASE_64BIT + KERNEL_BASE).
* mapped_delta field from preloaded_*_image removed, now handled compile-time
using the ELF*Class::Map method.
* Also link the kernel with -z max-page-size=0x1000, removes the need for
2MB alignment on the data segment (not going to map the kernel with large
pages for the time being).
The ELF loader now uses a new platform function, platform_allocate_elf_region,
which returns 2 addresses: the real load address and an address where the
region is mapped in the loader's address space. All of the ELF loading code
has been changed to access the load region through the mapped address rather
than the addresses contained in the ELF image. The ELF64 version of
platform_allocate_elf_region on x86 uses the existing MMU code, which maps
everything at 0x80000000, but returns the correct 64-bit address. The long
mode switch code will just set up the 64-bit address space with everything
remapped at the correct address.
* Extract the scrollbar change based on the mouse wheel delta into a protected
method of BView.
* Call that method from BScrollBar's MessageReceived.
With this change it is now a bit easier to scroll horizontally around the
system by putting the mouse cursor over a horizontal scrollbar and using the
wheel.
Fixes#8631.
* FixedWidthPointer:
- operators ==/!=: Change second operand type from void* to const
Type*. Also add non-const version to resolve ambiguity warning when
comparing with non-const pointer.
- Add Pointer() getter.
- Remove templatized cast operators. They are nice for casting the
pointer directly to another pointer type, but result in ambiguity.
* Make preloaded_image::debug_string_table non-const. Avoids clashes of
the const and non-coast FixedWidthPointer comparison operators. A
cleaner (but more verbose) solution would be to spezialize
FixedWidthPointer for const types.
The actual implementation of the ELF loading methods have been put into
an ELFLoader template class that takes a single template parameter, which
is a structure containing all the necessary ELF typedefs. It's a bit
verbose, but I thought it was a neater solution than using a bunch of
standalone functions with a huge number of template parameters. There is
no change to code outside of elf.cpp, the ELF32/ELF64 differences are
handled internally.
* There is now 2 structures, preloaded_elf32_image and preloaded_elf64_image,
which both inherit from preloaded_image.
* For now I've just hardcoded in use of preloaded_elf32_image, but the
bootloader ELF code will shortly be converted to use templates which use
the appropriate structure. The kernel will be changed later when I add
ELF64 support to it.
* All kernel_args data is now compatible between 32-bit and 64-bit kernels.
* Added a FixedWidthPointer template class which uses 64-bit storage to hold
a pointer. This is used in place of raw pointers in kernel_args.
* Added __attribute__((packed)) to kernel_args and all structures contained
within it. This is necessary due to different alignment behaviour for
32-bit and 64-bit compilation with GCC.
* With these changes, kernel_args will now come out the same size for both
the x86_64 kernel and the loader, excluding the preloaded_image structure
which has not yet been changed.
* Tested both an x86 GCC2 and GCC4 build, no problems caused by these changes.
I've tested this change on x86, causing no issues. I've checked over the code
for all other platforms and made the necessary changes and to the best of my
knowledge they should also still work, but I haven't actually built and
tested them. Once I've completed the kernel_args changes the other platforms
will need testing.
Pointers in kernel_args are going to be changed to unconditionally use 64-bit
storage (to make kernel_args compatible with both the x86 and x86_64 kernels).
KMessage stores a pointer to its buffer, however since KMessage is used
outside of the boot code it is undesirable to change it to use 64-bit storage
for the pointer as it may add additional overhead on 32-bit builds. Therefore,
only store the buffer address and size and then construct a KMessage from
those in the kernel.
The whole kernel now builds and there are no undefined references when
linking, I just need to fix some strange relocation errors I'm getting
(probably a problem with the linker script) and then I'll have a kernel
image.
Since ICI arguments are used to send addresses in some places, uint32 is
not sufficient on x86_64. addr_t still refers to the same type as uint32
(unsigned long) on other platforms, so this change only really affects
x86_64.
* x86_64 is using the existing *_ia32 boot platforms.
* Special flags are required when compiling the loader to get GCC to compile
32-bit code. This adds a new set of rules for compiling boot code rather
than using the kernel rules, which compile using the necessary flags.
* Some x86_64 private headers have been stubbed by #include'ing the x86
versions. These will be replaced later.
* gPeripheralBase keeps track of the device
peripherals before and after mmu_init
* Add ability to disable mmu for troubleshooting
* Remove static FB_BASE, we actually don't know
where the FB is yet. (depends on firmware used)
* BCM2708 defines no longer assume 0x20 address
We will be throwing away the blob memory mapping
and using our own.
* Use existing blob mapping to turn GPIO led on pre mmu_init
* Remap MMU hardware addresses from 0x7E. We could map each device,
however the kernel will throw away the mappings again anyway. For
now we just map the whole range and use offsets.
* Serial uart no longer works, however at least
we know why now :). Serial driver now needs to
use mapped address.
* Use U-Boot mmu code as base
* This will be factored out someday into common arch mmu
code when we can read Flattened Device Trees
* Move mmu_init after serial_init.
Temporary change as we will want serial_init to use
memory mapped addresses... for debugging.
* introduce a DebugUART baseclass,
* rework 8250 and PL011 implementations from kallisti5 to inherit DebutUART,
* each arch should override the IO methods to access registers.
* on ARM registers are 32bit-aligned.
* U-Boot still works for the verdex target.
* rPi still compiles, needs testing.
* Still some more consolidation needed to allow runtime choice of the UART type (as read from FDT blobs for ex.).
* serial.cpp should probably mostly be made generic as well.
* didn't touch x86 or ppc yet.
* Enable/Disable makes more sense and matches
platform loader serial functions.
* Rework PL011 code after finding a PDF covering
the details of it.
* Rename UART global defines in loader to be more
exact about location
* This makes things a little more flexible and
the interface to use the uarts cleaner.
* May want to make a generic Uart wrapper
class in uart.h / uart.cpp and call drivers
as needed from there.
* 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.
* Add nested function wrappers to allow usage of other
uart drivers depending on board. We may want to use this
on other platforms at some point (haha, maybe)
* Make Kernel ARM UART slightly more generic
through (BOARD_UART_CLOCK) configured per board
* Add initial Raspberry Pi serial code
* Still rough and non-working
* Change ShowTip() point parameter name to where.
* Add a parameterless ResetWindowFrame() overload that get's the current
where and calls ResetWindowFrame(BPoint where) which does the actual
work. FrameResized() calls this parameterless ResetWindowFrame()
method instead of doing the work in that method. This is functionaly
the same but allows me to call the parameterless ResetWindowFrame()
elsewhere.
SharedSolver was archiving too many constraints, partly because of
multiple typos, also because it archived some which were just artifacts
of the layout process. These extra constraints are created when the
layout calls SetRange() on the left/top/right/bottom tabs during layout.
* LinearSpec/ActiveSetSolver had to be adjusted to get access to the
constraints added by the SetRange() calls.
* BALM::TabBase was adjusted to avoid a segfault during unarchiving,
caused by an unitialized member.
* ALMFriendLayoutTest was adjusted to include a more obvious custom
constraint for testing.
Also make ALMGroup totally self-contained, i.e. BALMLayout no longer
does the parsing, and is completely unaware of ALMGroup. A small touch
of refactoring as well.
* allow for independent left, top, right and bottom insets
* allow for independent vertical and horizontal spacing between tabs
* allow for the usage of Haiku's spacing constants such as B_USE_WINDOW_INSETS
* The areas allocated for BBitmaps were never deleted, even though the
app_server deleted its part when the memory got freed.
* This resulted in a constant memory increase if the application in question
would operate on many changing large bitmaps, like photos.
* Since the bitmaps are reference counted, we don't actually know when to delete
the areas, so that the app_server now notifies the client whenever that is
possible.
* This might fix#6824.
* This removes the fVisibleToolTip member from BView, and fixes bug #5669;
BToolTipManager::ShowTip() now gets the owner of the tool tip as an extra
parameter.
* Removed the work-around to hide that bug.
* Improved ToolTipTest application to include more test cases like a view that
periodically update its tool tip via SetToolTip(const char*), and one that
sets a new tool tip every second.
* Furthermore, added a test that shows that inner views inherit the tool tip
of their parents.
* Fixed another bug in BToolTipManager::ShowTip() that would release an
extra reference to the tool tip currently shown.
* First steps at getting card command processor wired
up to the ring buffers.
* Code doesn't run yet as I have *no* idea what happens
when these rings are in an invalid state.
* rename B_TRANSLATE_CONTEXT to B_TRANSLATION_CONTEXT and
B_TRANSLATE_WITH_CONTEXT to B_TRANSLATE_CONTEXT, squashing a TODO
* adjust all uses of both macros in Haiku's source tree
* use correct header guard for collecting/Catalog.h
The renamed macros require adjustments to all external applications
using catalogs.
* Not turned on for default buttons and menuframes right now.
* Updated Deskcalc and Keymap to use buttons with rounded corners.
* Overloaded methods with radium parameters are not virtual right
now so as to not break vtables. Added /*virtual*/ before each
method that should be made virtual in ControlLook.h
* Added a light line to the left border of the down arrow frame
on menu frames as a small visual tweak.
* Replace StrokeRect() with StrokeRoundRect() when drawing the
default button indicator. This gives them a rounded
appearance if the button is also rounded.
* Added protected methods _DrawMenuFieldBackgroundOutside and
_DrawMenuFieldBackgroundInside.
* Created some protected methods to get the edge, frame, and bevel
colors from a passed in base color because it was a mess and I
needed to calculate the colors from mutiple methods. It is much
cleaner now.
* Added myself to ControlLook.cpp authors list. Assigned copyright
to Haiku, Inc. Stippi also retains his copyright.
* Tons of style fixes.

* adjust users of BCatalogAddOn accordingly

Added two new methods to the Locale Kit in order to create a custom time
formats from a format string. One method is outputs into a char* array,
the other into a BString() and you can set the timezone.
These methods should be cleaned up, we only need 2, one to get
the time in a predefined style, the other to get a custom time format.
Also should probably do the same for dates and datetimes. But I'll let
this go for now.
I added myself to the Locale.cpp file. I retained the copyright instead
of assigning it to Haiku, Inc. because the file is under the OpenBeOS
license and I don't know what the concequences of copyright sharing are
for that license, unlike MIT.
These new methods are used to generate custom time formats in Deskbar.
Instead of using a set of Radio Buttons to choose between the predefined
time options I build my own by creating a format string and passing it
to the Locale Kit. The format string is generated from 3 checkboxes,
show seconds, show day of week, and show time zone. You can mix and match
between them choose any that you like. By default they are all off.
There are 3 new deskbar settings associated with these new options:
showSeconds, showDayOfWeek, and showTimeZone. timeFormat has gone away.
The time format string gets cached and updated only when Update() gets called
on the TimeView class.
In order to fit all the options in (there is 1 more than before) I had to
reduce the font size of the clock to 11pt when all options are turned on in
12 hour mode. For those with no imagination it looks like this:
http://imagebin.org/208162
Renamed "Open time preferences..." menuitem to "Time preferences...".
Renamed "Show Time" and "Hide Time" to "Show time" and "Hide time".
Other changes include refactoring the header files a bit. There were a lot
of headers included by header files uneccessarily. For instance BarWindow.h
now only includes <Window.h> and <Deskbar.h>. This change is mainly to
to speed up the compile time since it takes a while right now.
I copy the fBarView pointer from BarWindow in the BarApp constructor and then
use that throughout the file rather than getting the pointer from the window
each time by calling BarView(). BarView() is still available in the header
for other classes though.
I moved some message constants around since it was getting a bit jumbled.
Most of the messages related to settings are in PreferenceWindow.h.
fChangeState is moved to BarView.h since that is where the ChangeState()
function is and BarView.cpp uses that constant.
The time interval and format constants are in TimeView.h.
Make some methods public in their respective classes where it made sense.
The preference window methods to update dependent items are public, that
might get called from BarWindow when a message gets received at some point.
Also made ShowHideTime() and Time() public in StatusView.h. These methods
activate showing and hiding the clock and return the fTime clock object.
No reason they should be private.
I reindented the StatusView.h and PreferenceWindow.h headers to the standard
style. Question here, are the public: protected: and private: lines inside
of classes suppose to get indented 1 tab or not? I've seen both, the style
guide says no indent but 1 indent seems reasonable and looks pretty good.
Style fixes here and there. That's enough for one commit I think.
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.

The gcc2 cross-compiler built on Mac OS X Lion has a bug in it
where it is erroring with 'cast specifies signature type' when
assigning 0 or NULL to a pointer to a member fuction. NULL in this
instance is correctly converted to 0 since it is illegal to assign
((void*)0) to a pointer to a member function. However, it should
be legal to assign 0 to a pointer to a member function. Thus, there
is a bug. Since I can't fix the gcc2 compiler I am working around
this bug by assigning the pointer to a do nothing function instead.
My host compiler version is
i686-apple-darwin11-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)
The same error occurs using the default gcc-llvm compiler and
a standard gcc 4.61 built from source. This bug does not occur on
Mac OS X 10.6 gcc2 or gcc4, nor does it occur on Mac OS X 10.7 with
the gcc4 cross-compiler.
If and when we decide to finally leave gcc2 behind we can revert this
change.
