This also implements the fault handler correctly now, and cleans up the
exception handling. Seems a lot more stable now, no unexpected panics or
faults happening anymore.
* Before, you had to have both, the text view layout item, and the label
layout item or else nothing would ever be visible.
* Now you can only create the text view item, and it will still work.
* Also, no matter the order you added the layout items, they would always
put the label on the left, and the control to the right.
* You can place the label and text view layout items anywhere now, although
you should keep in mind that the view spans over their frame unions; IOW
they should always adjacent to each other, but not necessarily horizontally
and left to right.
* No longer uses a fixed label spacing, but utilizes
BControlLook::DefaultLabelSpacing() instead.
* However, the spacing is always added to the right of the label, no matter
how you place it in the layout. Maybe one wants to add a SetLabelTextViewGap()
like method.
* Adjust BTextView to use B_COMMAND_KEY instead of B_CONTROL_KEY
for wordwise navigation and jumping to the top and bottom.
This requires a shortcut, which is only installed if there is
none already (for the groups B_LEFT_ARROW/B_RIGHT_ARROW and
B_HOME/B_END). As a result, wordwise navigation no longer works
in Mail, for instance.
* drop "protected" from bsd-compat header sys/cdefs.h, as that define
pollutes the global namespace and at least FreeBSD doesn't provide
it anymore
* remove all uses of that macro from libedit, which seems to be the
only user in our tree
* The only implementation that would accept more than 2 TB was the one in
scsi_disk. But even that one was limited to 63 TB.
* Now there is a new utility function devfs_compute_geometry_size() which
does it correctly for sizes up to 2^64 which should be good enough for
quite some time :-)
* This fixes bug #8992.
* When we do not have a predefined model string, we now try to parse
the reported model string into something that is at least usable,
and should look comparable to what we have now.
* For models where the parsed type string is acceptable, we could remove
the predefined ones.
- BNavMenu now keeps its own copy of the cached types list that's passed to it.
In some circumstances it could happen that the container window would
delete the list and consequently the nav menu would wind up with a pointer
to an invalid object. Probably a regression from the async mouse tracking
rewrites.
The lowest 4 bits of the MSR serves as a hint to the hardware to
favor performance or energy saving. 0 means a hint preference for
highest performance while 15 corresponds to the maximum energy
savings. A value of 7 translates into a hint to balance performance
with energy savings.
The default reset value of the MSR is 0. If BIOS doesn't intialize
the MSR, the hardware will run in performance state. This patch
initialize the MSR with value of 7 for balance between performance
and energy savings

Renamed {32,64}/int.cpp to {32,64}/descriptors.cpp, which now contain
functions for GDT and TSS setup that were previously in arch_cpu.cpp,
as well as the IDT setup code. These get called from the init functions
in arch_cpu.cpp, rather than having a bunch of ifdef'd chunks of code
for 32/64.
* made private Catalog.h header public by moving it to
os/locale/tools/CollectingCatalog.h
* reintroduce B_COLLECTING_CATKEYS define (which is expected to be set
during a collectcatkeys session) in order to decide whether or not
to automatically include the CollecingCatalog.h header from Catalog.h
* adjust jam rule for collecting catalog keys accordingly
This also matches the client_window_info.show_hide_level field used in Deskbar
and other applications.
While doing this, keep fShowLevel fully in sync between BWindow and app_server,
use one message type for both hiding and showing, and make the decision to show
and hide the window in the app_server.
Lastly make minimize behave as described in the Be Book: hidden windows cannot
be minimized, and minimized windows which get hidden become unminimized.
* fs_darwin.c => fs_darwin.cpp
* fs_freebsd.c => fs_freebsd.cpp
* use bool instead of int again in fs_darwin.cpp (C => C++)
* declare loop varibles inline again in fs_freebsd.cpp (C => C++)
* 2 newlines between top header gaurd and first #include
* 2 newlines after last #include
* freebsd/endian.h and freebsd/regex.h convert \r\n to just \n
* remove some leading tabs in fs_freebsd.cpp
* add newlines after single line if statement in fs_freebsd.cpp
* 80-char limit fixes in fs_freebsd.cpp
This completes the final 1/3 of #8857. Changes again by nielx with
style fixes by me.
The one part that I couldn't figure out, and maybe Ingo can chime
in here. If headers/build/host/darwin/sys/stat.h is surrounded in
extern "C" {
}
guards then I get a link error complaining that the functions defined
here are duplicate symbols, once in fs.o and once in function_remapper.o.
For example:
ld: duplicate symbol _futimens in generated/objects/darwin/x86_64/release/build/libroot/libroot_build_function_remapper.a(function_remapper.o) and generated/objects/darwin/x86_64/release/build/libroot/libroot_build.a(fs.o) for architecture x86_64
I'm not sure why that is.
* Various compilation fixes.
* Fixes to the FreeBSD compatibility layer (from comparing the x86-
specific bits with the equivalent amd64 sources in FreeBSD).
* Compile all the Ethernet drivers except for sis900 and wb840, these
require a bit more work to fix (will file a ticket soon). Tested
ipro1000 and rtl81xx, no issues.
Reused x86 arch_user_debugger.cpp, with a few minor changes to make
the code work for both 32 and 64 bit. Something isn't quite working
right, if a breakpoint is hit the kernel will hang. Other than that
everything appears to work correctly.
There were two problems with the last commit:
* the list needed to be outside of the top-level loop.
* BList was just broken for sorting translation_format pointers.
I fixed this by moving the loop outside and converting the translation_formats
to translator_info, which has the translator_id, since that is needed to create
the menu item, and would otherwise be unavailable outside the loop.
I tried to get this working with BList, but the sorting was completely broken,
and converting to BObjectList made the code much, much better and worked great.
Screw BList and casting, hurray templated BObjectList.
Really fixes#6782.
This is used by ShowImage and CodyCam to create a list of image formats which a
file can be saved as. Tracker sorts the image MIME types used in the Find
window by name, so this makes these Save As menus match that (minus the icons
which I think are superfluous.)
Fixes#6782.
If the use of BList is no longer recommended, I welcome better suggestions
for sorting which will work in both GCC2 and GCC4. But this works ;)
* Remove non-generic radeon dp_get_lane_count
* Set lane count and link rate at set_display_mode
* Pass entire mode to pll_set vs only pixel clock for DP code
* Add helpers for DP config data to common code
* Obtain more correct link rate
With this commit, app_server now compiles and runs at boot! Nothing
particularly interesting happens, just the blue background and a mouse
pointer. Remote backends are broken and not compiled in, see #8834.
Note that it won't be possible to build this quite yet, need to get
the FreeType package uploaded.
No functional change.
* Surround email addresses in angle brackets.
* Add myself to ExpressionParser.cpp and .h
* Remove myself from ExpressionTextView.cpp and .h
* Alphatetize authors by last name.
Thanks Ingo and Axel.
This module provides an interface for drivers to use to perform calls
to the BIOS (only really for use by graphics drivers which need to use
the VESA BIOS). It uses the x86emu library from X.org which emulates
a real mode x86 CPU. This is necessary for x86_64 as virtual 8086 mode
no longer exists there.
* Changed IS_USER_ADDRESS to check an address using USER_BASE and
USER_SIZE, rather than just !IS_KERNEL_ADDRESS. The old check would
allow user buffers to point into the physical memory map area.
* Added an unmapped hole at the end of the bottom half of the address
space which catches buffers that cross into the uncanonical address
region. This also removes the need to check for uncanonical return
addresses in the syscall handler, it is no longer possible for the
return address to be uncanonical under normal circumstances. All
cases in which the return address might be changed by the kernel
are still handled via the IRET path.
* This puts the registers in a better state and ensures
all model dependant defines are prefixed with card series
* Consolidate evergreen defines into single header
Default is radian mode, You set the option in the right click menu
like the other options.
Note: degree mode does not affect hyperbolic trigonometric functions.
This is how Mac Calculator, Windows Calculator, and Google Calculator
work.
Fixed the usual issues - printf format strings, uint32 instead of
addr_t, etc. One thing that isn't so nice is several places where
BList is used to store (u)int32, these require a double cast to addr_t
then void* to silence a warning on x86_64.
The cookie is used to store the base address of the area that was just
visited. On 64-bit systems, int32 is not sufficient. Therefore, changed
to ssize_t which retains compatibility on x86 while expanding to a
sufficient size on x86_64.
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.
Haiku implements file locking at vfs level. That would not work for remote
and shared file systems, since they need to negotiate locks with peers.
This patch introduces three additional hooks in fs_interface that allow
file system module to take over the management of file locks.
recv on UDP sockets is not interrupted when the socket is closed.
Additionaly, signals do not interrupt kernel threads, that is why
new function interrupt_thread was implemented in order to cancel
listener thread.
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
