* __pthread_destroy_thread() will in turn free the pthread_thread object.
* this fixes a leak of 2072 bytes on each thread construction/destruction
and #9945. MediaExtractor spawns a thread on construction, which leaked
its pthread_thread object on destuction.
If the alternate signal stack is used randomize the initial stack
pointer in the same way it is randomized on "normal" thread stacks.
Also, update MINSIGSTKSZ value so that regardless of where the new
stack pointer points to there is at least 4k of stack left.
* imported asc-num.txt as a reference, was used to generate the asc sense table.
* use the sense asc and key tables to know which action and status codes are
to be applied.
* tested with an hard disk and a dvd reader.
* these tables could be reused by the scsi_periph module.
Taking a page from HaikuDepot's book, remove the border from the tab
view and set the inset to 0 in order to position the tabview right on
the window's edge. Looks a bit better than the previous method since
the tabview border appeared to extend the thickness of the window
border.
It references a non-existing device in the aliases, just comment
it out until we sort out with upstream what's up.
(Since we've also added PXA devices to the Verdex definition we
need to chat with them anyway)
Both for the rPI and the Verdex target we now have FDTs. The verdex
DTS is homebrew, the pxa DTSIs come from Linux and should be kept
in sync.
The rPI DTS and Broadcom DTSI come from FreeBSD HEAD, and should
ofcourse also be kept in sync.
One global new Jam rule has been introduced for handling DTS
compilation, aptly named CompileDTS....
More coming!
This is especially important for the assembler code in the kernel,
since it enables workarounds for some critical errata related to
exception handling.
Support for 64-bit atomic operations for ARMv7+ is currently stubbed
out in libroot, but our current targets do not use it anyway.
We now select atomics-as-syscalls automatically based on the ARM
architecture we're building for. The intent is to do away with
most of the board specifics (at the very least on the kernel side)
and just specify the lowest ARMvX version you want to build for.
This will give flexibility in being able to distribute a single
image for a wide range of devices, and building a tuned system
for one specific core type.
This adds the -mapcs-frame compiler flag for ARM to have "stable"
stack frames, adds support to the kernel for dumping stack crawls,
and initial support for iframes. There' much more functionality
to unlock in KDL, but this makes debugging already a lot more
comfortable.....
Since both platforms can boot the same kernel we must accept either
arg, so we make sure they are identical for now.
TODO: use a union or KMessage maybe?
- Since we actually draw a selection now, change the target address
highlight to clearly distinguish it. Rather than inverting it, it's
now drawn with a normal background and red text in the hex display.
The text mode subcomponent still shows it as an invert though, since
the latter doesn't currently indicate the selection.
- Always grab the address value from the actual register value column,
rather than the one that's in fact under the mouse. Fixes the "Inspect"
item sending you to inspect address 0 if you happened to right click over
the register name rather than the value.
- The offset calculation for mapping the current point wasn't taking
into account the number of bytes per hex block, causing it to be
proportionally further off if one switched to 16/32/64-bit hex mode.
Gets mouse selection working properly in said modes.
This helps when debugging, since when a driver/module causes a crash
while registering with the device manager, you can actually look at
the device manager state ;-)
The previously used method for programming the timer did not take
into account that our timespec is 64bit while the register we poke
it into is 32 bit. Since the PXA (SoC in Verdex target) has a limited
scale of resolution (us,ms,second) we dynamicly determine the one
that we can most closely match, and set that.
For f.ex. snooze to work however, we also need system_time to work.
The current implementation uses a system timer at microsecond
resolution to keep track of time.
Although the code is far from perfect, committing it now before
it gets lost, since I'm working on the infrastructure code
to properly factor out the SoC specific code out of the core
ARM architecture code (so the kernel can support more then
our poor old Verdex QEMU target ;))
The "blobs" in a U-Boot uimage are aligned at 4 bytes, which we
did not take into account. Found this when adding a 3rd blob
containing the Flattened Device Tree for ARM.
As korli suggested use B_PAGE_SIZE for defining stack size related
definitions what seems to be more natural for them and also may
help if we ever support an architecture with page size different than
4kB.
* Seems like there was no easy way to simply invalidate
a given BRow. Introduced BColumnListView::InvalidateRow().
* BRow::SetField() tried to invalidate the row, but invalidated
the listview instead of the BOutlineView responsible for
drawing the list contents. Use the new InvaalidateRow().
- B_PRIx8 unfortunately doesn't necessarily strictly stay within the bounds
of an 8-bit hex constant, so force the size passed to snprintf to make it
that way.
- The Inspector's memory view now supports selecting chunks of the hex display in
the manner one would in a TextView. The selection can also be copied to the clipboard,
or if it matches the size of a target address, can be used as input for an address to
inspect directly.
Still needs some fine tuning, but basically works.
