This is an oversized hammer for sure, but we have to make sure the
layout tree gets rebuilt in case the object representation changes.
Since "throw out the entire layout tree" is the finest tool we have
right now, it'll have to do.
This fixes an issue where the eyes on Acid2 would sometimes not show up
until the next layout invalidation occurred.
This version of 'dosbox-staging' uses the meson build system.
Previous versions of dosbox-staging started in windowed mode with a
resolution of 320x200. This version starts in windowed mode with a
resolution of 640x480.
Audio was stuttering a bit in previous versions, but it sounds like it
might have become a bit worse. This is probably because of higher CPU
usage and the audio server/client not able to keep up.
Added a post_install() section to package script which outputs a link to
dosbox-staging's release notes.
Layout will be identical for both of those values, so only a repaint is
necessary. If it changes to/from "collapse" however, we do need to
relayout. This means we can't simply use the "affects-layout" mechanism.
We have to write a little bit of custom code.
This makes Google Groups (and surely many other sites) significantly
more responsive by avoiding large amounts of layout work.
This is in preparation for adding MSI(x) support to the NVMe device.
NVMeInterruptQueue needs access to the PCI device to deal with MSI(x)
interrupts. It is ok to pass the NVMeController as a reference to the
NVMeQueue as NVMeController is the one that owns the NVMeQueue.
This is very similar to how AHCIController passes its reference to its
interrupt handler.
Add an explicit QueueType enum which could be used to create a poll or
an interrupt queue. This is better than passing an Optional<irq>.
This refactoring is in preparation for adding MSIx support to NVMe.
PCIIRQHandler is a generic IRQ handler that the device driver can
inherit to use either Pin or MSI(x) based interrupt mechanism.
The PCIIRQHandler can do what the existing IRQHandler can do for pin
based interrupts but also deal with MSI based interrupts. We can
hopefully convert all the PCI based devices to use this handler so that
MSI(x) can be used.
Add reserve_irqs, allocate_irq, enable_interrupt and disable_interrupt
API to a PCI device.
reserve_irqs() can be used by a device driver that would like to
reserve irqs for MSI(x) interrupts. The API returns the type of IRQ
that was reserved by the PCI device. If the PCI device does not support
MSI(x), then it is a noop.
allocate_irq() API can be used to allocate an IRQ at an index. For
MSIx the driver needs to map the vector table into the memory and add
the corresponding IRQ at the given index. This API will return the
actual IRQ that was used so that the driver can use it create interrupt
handler for that IRQ.
{enable, disable}_interrupt API is used to enable or disable a
particular IRQ at the given index. It is a noop for pin-based
interrupts. This could be used by IRQHandler to enable or disable an
interrupt.
MSIx table entry is used to program interrupt vectors and it is
architecture specific. Add helper functions declaration in
Arch/PCIMSI.h. The definition of the function is placed in the
respective arch specific code.
Add a struct named MSIxInfo that stores all the relevant MSIx
information as a part of PCI DeviceIdentifier struct.
Populate the MSIx struct during the PCI device init. As the
DeviceIdentifier struct need to populate MSIx info, don't mark
DeviceIdentifier as const in the PCI::Device class.
MSI(x) interrupts need to reserve IRQs so that it can be programmed by
the device. Add an API to reserve contiguous ranges of interrupt
handlers so that it can used by PCI devices that use MSI(x) mechanism.
This API needs to be implemented by aarch64 architecture.
Set pin-based interrupt handler as reserved during PCI bus init.
This is required so that MSI(x) based interrupts can avoid sharing the
IRQ which has been marked as reserved.
Pin-based PCI device are allocated an IRQ, and it could be shared with
multiple devices. An interrupt handler with an IRQ for a PCI device
will get registered only during the driver initialization.
For MSI(x) interrupts, the driver has to allocate IRQs and this field
can be used to skip IRQs that have already been reserved by pin-based
interrupts so that we don't have to share IRQs, which generally will
reduce the performance.
We should only rely on LibGfx to decode images for us, if LibGfx
can't decode an image that should be motivation to improve LibGfx,
not hidden by Qt picking up the slack :^)
Fixes incorrect thread highlighting for ResourceGraph panels.
Prior to FrameStyles, these graphs were painted as faux-panels,
this is, sunken containers with a thickness of 1, and weren't
subject to the bug.
If something else has already caused a layout, there's no need to force
a new relayout when the layout timer fires.
This avoids a lot of redundant work on many pages. :^)
This adds information about the user owning the process to our netstat
output. We do not fully match the behaviour of Linux as we don't show
an inode information.
The Font class now remembers the results of kerning lookups in a
HashMap. This fixes an issue where text-heavy UI (like WidgetGallery)
would lag when using a UI font with kerning data.
Instead of testing all possible code to find the good symbol, we use a
lookup table to directly find the expected symbol. This method is used
by most Huffman decoder (gzip or libjpeg-turbo).
In order to use the correct key when peeking a constant number of bits
from the stream, we generate duplicates in the table. As an example, for
the code 110, all entries with that pattern 110***** will be set to
110's symbol. So, when you read this code plus garbage from following
codes, you still find the correct symbol.
