5f7bb9d072 malloc: Make it possible to recycle big allocation blocks as well. 
This patch makes us recycle up to 8 blocks of 4KB size. This should
probably be extended to handle other sizes.

1e0f9d325c LibCore: Avoid a big malloc in CIODevice's internal buffering. 
This heap allocation was totally avoidable and can be replaced by a stack
buffer instead. Dodges a bunch of mmap() traffic.

7c10a93d48 Kernel: Make allocate_kernel_region() commit the region automatically. 
This means that kernel regions will eagerly get physical pages allocated.
It would be nice to zero-fill these on demand instead, but that would
require a bunch of MemoryManager changes.

9e2116ff6b Kernel: Signal stacks are lazily allocated so don't crash in getter. 2019-05-14 12:17:59 +02:00

486c675850 Kernel: Allocate kernel signal stacks using the region allocator as well. 2019-05-14 12:06:09 +02:00

c8a216b107 Kernel: Allocate kernel stacks for threads using the region allocator. 
This patch moves away from using kmalloc memory for thread kernel stacks.
This reduces pressure on kmalloc (16 KB per thread adds up fast) and
prevents kernel stack overflow from scribbling all over random unrelated
kernel memory.

dab9901235 WindowServer+LibGUI: Handle mouse wheel deltas in the mouse event stream. 
The wheel events will end up in GWidget::mousewheel_event(GMouseEvent&)
on the client-side. This patch also implements basic wheel scrolling in
GScrollableWidget via this mechanism. :^)

dae8eb6454 Kernel: Add support for the PS/2 mouse wheel if detected. 2019-05-13 19:48:14 +02:00

b7166385de RetroFetch: Add a silly neofetch-like program. 
The idea is to print out various system info suitable for screenshots. :^)

Andreas Kling
43604bf71a LibC+Shell: Make system() actually work. 
system() will now fork off a child process and execute the command via
/bin/sh -c. There are probably some things to fix here, but it's a start.

42cf09fdf1 WindowServer: Don't add maximize button to non-resizable windows. 
The minimize button can stay though, since it doesn't change the window
size, just the visibility. :^)

8c4b7fe385 WindowServer: Make the ordering in the window switcher a bit more sane. 2019-05-13 00:08:56 +02:00

dddf45f563 Change String&& arguments to const String& in a couple of places. 
String&& is more nuisance than anything, and the codegen improvement is
basically negligible since the underlying type is already retainable.

641d55c7ef Painter: Always optimize with -O3. 
Use a GCC #pragma to always optimize the Painter code with -O3.
This code is performance critical and hotter than anything else in the
system, and this helps quite a bit.

The 2x, 3x and 4x upscaling fast paths benefit greatly from this.

Andreas Kling
788fb7699b Painter: Simplify the draw_scaled_bitmap() fast path for integer scale. 
Iterate over the source image instead of the destination image, and blow it
up pixel by pixel. This code will only run for upscaling so we don't need
to worry about anything else.

1652cb7db9 Painter: Fix typo in 4x scaling fast path. 2019-05-11 16:00:25 +02:00
Andreas Kling
e2c2a4c6d7 Painter: Add a fast path for draw_scaled_bitmap() with integer scale. 
When both the x and y scale factors are integers, we can avoid a whole bunch
of the pixel lookups in the source image.

This makes 2x scaling a 320x200 bitmap another ~25% faster. :^)
 2019-05-11 05:34:20 +02:00
Andreas Kling
91a4b60d66 Painter: Templatize the inner loop of draw_scaled_bitmap(). 
Use templates to specialize draw_scaled_bitmap() so we don't have to blend()
for source without alpha, and also inline the GraphicsBitmap::get_pixel()
logic so we don't have to branch on the bitmap format on every iteration.

This is another ~30% speedup on top of the previous changes. :^)

ab42180e83 Fix some more victims of the new default layout spacing. 2019-05-11 03:06:18 +02:00
Andreas Kling
e491dd2125 Painter: Improve draw_scaled_bitmap() performance. 
- Removed extra bounds checking.
- Converted it to use integer math for the scale factors.
- Using blend() for everything.

1ab66e4d33 FileManager: Tweak layout spacing (new default looks weird here.) 
This app needs a layout rethink, but for now I'm just fixing breakage.

565f073796 Terminal: Give the terminal widget a sunken container look. 
This blends perfectly with the new window frames. :^)

allow the user to hide/show individual columns.

dbf7878998 LibCore: Using printf() inside CIODevices will now call CIODevice::printf(). 
Well this was confusing. Obviously this code should never be calling outside
to ::printf() anyway, so just use dbgprintf() instead.

090e14d42c IPv4: Default initialize IPv4Address to 0.0.0.0. 
IPv4Address() didn't initialize which made for some confusing debugging.

We then use this immediately in the WindowServer/LibGUI communication in
