4 daysui/gtk: Add scale optionWeifeng Liu1-17/+29
Allow user to set a preferred scale (defaulting to 1) of the virtual display. Along with zoom-to-fix=false, this would be helpful for users running QEMU on hi-dpi host desktop to achieve pixel to pixel display -- e.g., if the scale factor of a user's host desktop is set to 200%, then they can set a 0.5 scale for the virtual display to avoid magnification that might cause blurriness.

When aspect ratio of host window and that of guest display are not aligned, we can either zoom the guest content to fill the whole host window or add padding to respect aspect ratio of the guest. Add an option keep-aspect-ratio to allow users to select their preferred behavior in this case.

4 daysui/spice: Blit the scanout texture if its memory layout is not linearVivek Kasireddy1-6/+75
In cases where the scanout buffer is provided as a texture (e.g. Virgl) we need to check to see if it has a linear memory layout or not. If it doesn't have a linear layout, then blitting it onto the texture associated with the display surface (which already has a linear layout) seems to ensure that there is no corruption seen regardless of which encoder or decoder is used.

4 daysui/spice: Create a new texture with linear layout when gl=on is specifiedVivek Kasireddy2-0/+88
Since most encoders/decoders (invoked by Spice) may not work properly with tiled memory associated with a texture, we need to create another texture that has linear memory layout and use that instead. Note that, there does not seem to be a direct way to indicate to the GL implementation that a texture's backing memory needs to be linear. Instead, we have to do it in a roundabout way where we need to first create a tiled texture and import that as a memory object to create a new texture that has a linear memory layout.

4 daysui/spice: Add an option to submit gl_draw requests at fixed rateVivek Kasireddy2-10/+64
In the specific case where the display layer (virtio-gpu) is using dmabuf, and if remote clients are enabled (-spice gl=on,port=xxxx), it makes sense to limit the maximum (streaming) rate (refresh rate) to a fixed value using the GUI refresh timer. Otherwise, the updates or gl_draw requests would be sent as soon as the Guest submits a new frame which is not optimal as it would lead to increased network traffic and wastage of GPU cycles if the frames get dropped.

Newer versions of Spice server should be able to accept dmabuf fds from Qemu for clients that are connected via the network.

5 daysui/vnc: Introduce the VncWorker typeAkihiko Odaki7-388/+405
The worker thread copies data in VncState to avoid race, but some data are too big to copy. Such data are held with pointers to avoid the overhead to copy, but it requires tedious memory management and makes them vulnerable to race. Introduce the VncWorker type to contain all data shared without copying. It allows allocating and freeing all shared data at once and shows that the race with the worker thread needs to be taken care of when accessing them.

2025-06-23ui/vnc: Update display update interval when VM state changes to RUNNINGJuraj Marcin2-0/+14
If a virtual machine is paused for an extended period time, for example, due to an incoming migration, there are also no changes on the screen. VNC in such case increases the display update interval by VNC_REFRESH_INTERVAL_INC (50 ms). The update interval can then grow up to VNC_REFRESH_INTERVAL_MAX (3000 ms). When the machine resumes, it can then take up to 3 seconds for the first display update. Furthermore, the update interval is then halved with each display update with changes on the screen. If there are moving elements on the screen, such as a video, this can be perceived as freezing and stuttering for few seconds before the movement is smooth again. This patch resolves this issue, by adding a listener to VM state changes and changing the update interval when the VM state changes to RUNNING. The update_displaychangelistener() function updates the internal timer, and the display is refreshed immediately if the timer is expired.

In fixed-scale mode (zoom-to-fit=false), we expect that scale should not change, meaning that if window size is larger than guest surface, padding is supposed to be added to preserve the scale. However, in OpenGL mode (gl=on), guest surface is always painted to the whole canvas without any padding. This change tries to fix this bug by adding appropriate padding when drawing surfaces.

2025-05-24ui/gtk: Consider scaling when propagating ui infoWeifeng Liu1-2/+23
The ui width and height sent to guest is supposed to be in buffer coordinate. Hence conversion is required. If scaling (global window scale and zooming scale) is not respected in non-free-scale mode, window size could keep changing because of the existence of the iteration of the following steps: 1. In resize event or configure event, a size larger (or smaller) than the currently used one might be calculated due to not considering scaling. 2. On reception of the display size change event in guest, the guest might decide to do a mode setting and use the larger (or smaller) mode. 3. When the new guest scan-out command arrives, QEMU would request the window size to change to fit the new buffer size. This will trigger a resize event or a configure event, making us go back to step 1.

2025-05-21ui/vnc: take account of client byte order in pixman formatDaniel P. Berrangé3-9/+11
The set_pixel_conversion() method is responsible for determining whether the VNC client pixel format matches the server format, and thus whether we can use the fast path "copy" impl for sending pixels, or must use the generic impl with bit swizzling. The VNC server format is set at build time to VNC_SERVER_FB_FORMAT, which corresponds to PIXMAN_x8r8g8b8. The qemu_pixman_get_format() method is then responsible for converting the VNC pixel format into a pixman format. The VNC client pixel shifts are relative to the associated endianness. The pixman formats are always relative to the host native endianness. The qemu_pixman_get_format() method does not take into account the VNC client endianness, and is thus returning a pixman format that is only valid with the host endianness matches that of the VNC client. This has been broken since pixman was introduced to the VNC server: commit 9f64916da20eea67121d544698676295bbb105a7 Author: Gerd Hoffmann <kraxel@redhat.com> Date: Wed Oct 10 13:29:43 2012 +0200 pixman/vnc: use pixman images in vnc. The flaw can be demonstrated using the Tigervnc client by using vncviewer -AutoSelect=0 -PreferredEncoding=raw server:display connecting from a LE client to a QEMU on a BE server, or the reverse. The bug was masked, however, because almost all VNC clients will advertize support for the "tight" encoding and the QEMU VNC server will prefer "tight" if advertized. The tight_pack24 method is responsible for taking a set of pixels which have already been converted into client endianness and then repacking them into the TPIXEL format which the RFB spec defines as "TPIXEL is only 3 bytes long, where the first byte is the red component, the second byte is the green component, and the third byte is the blue component of the pixel color value" IOW, the TPIXEL format is fixed on the wire, regardless of what the VNC client declare as its endianness. Since the VNC pixel encoding code was failing to honour the endian flag of the client, the tight_pack24 method was always operating on data in native endianness. Its impl cancelled out the VNC pixel encoding bug. With the VNC pixel encoding code now fixed, the tight_pack24 method needs to take into account that it is operating on data in client endianness, not native endianness. It thus may need to invert the pixel shifts. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>

2025-05-06ui/dmabuf: extend QemuDmaBuf to support multi-planeQiang Yu4-33/+65
mesa/radeonsi is going to support explicit modifier which may export a multi-plane texture. For example, texture with DCC enabled (a compressed format) has two planes, one with compressed data, the other with meta data for compression. v2: * change API qemu_dmabuf_get_fd/offset/stride to qemu_dmabuf_get_fds/offsets/strides. * change API qemu_dmabuf_dup_fd to qemu_dmabuf_dup_fds. * add an extra arg to these API for the length of the array.

2025-03-05ui/console-vc: implement DCH (delete) and ICH (insert) commandsRoman Penyaev1-0/+88
This patch implements DCH (delete character) and ICH (insert character) commands. DCH - Delete Character: "As characters are deleted, the remaining characters between the cursor and right margin move to the left. Character attributes move with the characters. The terminal adds blank spaces with no visual character attributes at the right margin. DCH has no effect outside the scrolling margins" [1]. ICH - Insert Character: "The ICH sequence inserts Pn blank characters with the normal character attribute. The cursor remains at the beginning of the blank characters. Text between the cursor and right margin moves to the right. Characters scrolled past the right margin are lost. ICH has no effect outside the scrolling margins" [2]. Without these commands console is barely usable.

2025-03-05ui/console-vc: add support for cursor DECSC and DECRC commandsRoman Penyaev1-6/+34
There are aliases for save and restore cursor commands: * save cursor `ESC 7` (DEC Save Cursor [1], older VT100) `ESC [ s` (CSI Save Cursor, standard ANSI) * load cursor `ESC 8` (DEC Restore Cursor [2], older VT100) `ESC [ u` (CSI Restore Cursor, standard ANSI) This change introduces older DEC sequencies for compatibility with some scripts (for example [3]) and tools. This change also adds saving and restoring of character attributes, which is according to the VT spec [1][2] [1] https://vt100.net/docs/vt510-rm/DECSC.html [2] https://vt100.net/docs/vt510-rm/DECRC.html [3] https://wiki.archlinux.org/title/Working_with_the_serial_console#Resizing_a_terminal Signed-off-by: Roman Penyaev <r.peniaev@gmail.com> Cc: "Marc-André Lureau" <marcandre.lureau@redhat.com> Cc: qemu-devel@nongnu.org Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-ID: <20250226075913.353676-5-r.peniaev@gmail.com>
2025-03-05ui/console-vc: report cursor position in the screen not in the scroll bufferRoman Penyaev1-2/+1
The format of the CSI cursor position report is `ESC[row;columnR`, where `row` is a row of a cursor in the screen, not in the scrollback buffer. What's the difference? Let's say the terminal screen has 24 lines, no matter how long the scrollback buffer may be, the last line is the 24th. For example the following command can be executed in xterm on the last screen line: $ echo -en '\e[6n'; IFS='[;' read -sdR _ row col; echo $row:$col 24:1 It shows the cursor position on the current screen and not relative to the backscroll buffer. Before this change the row number was always increasing for the QEMU VC and represents the cursor position relative to the backscroll buffer.

2025-03-05ui/console-vc: report to the application instead of screen renderingRoman Penyaev1-4/+3
Terminal Device Status Report (DSR) [1] should be sent to an application, not rendered to the screen. This patch fixes rendering of terminal report, which appear only on the graphical screen of the terminal (console "vc") and can be reproduced by the following command: echo -en '\e[6n'; IFS='[;' read -sdR _ row col; echo $row:$col Command requests cursor position and waits for terminal response, but instead, the response is rendered to the graphical screen and never sent to an application. Why bother? Busybox shell (ash) in Alpine distribution requests cursor position on each shell prompt (once <ENTER> is pressed), which makes a prompt on a graphical screen corrupted with repeating Cursor Position Report (CPR) [2]: [root@alpine ~]# \033[57;1R] Which is very annoying and incorrect.

2025-03-05ui/console-vc: introduce parsing of the 'ESC ( <ch>' sequenceRoman Penyaev1-0/+16
This change introduces parsing of the 'ESC ( <ch>' sequence, which is supposed to change character set [1]. In the QEMU case, the introduced parsing logic does not actually change the character set, but simply parses the sequence and does not let output of a tool to be corrupted with leftovers: `top` sends 'ESC ( B', so if character sequence is not parsed correctly, chracter 'B' appears in the output: Btop - 11:08:42 up 5 min, 1 user, load average: 0BB Tasks:B 158 Btotal,B 1 Brunning,B 157 Bsleeping,B 0 BsBB %Cpu(s):B 0.0 Bus,B 0.0 Bsy,B 0.0 Bni,B 99.8 Bid,B 0.2 BB MiB Mem :B 7955.6 Btotal,B 7778.6 Bfree,B 79.6 BB MiB Swap:B 0.0 Btotal,B 0.0 Bfree,B 0.0 BB PID USER PR NI VIRT RES SHR S B B 735 root 20 0 9328 3540 3152 R B B 1 root 20 0 20084 10904 8404 S B B 2 root 20 0 0 0 0 S B [1] https://vt100.net/docs/vt100-ug/chapter3.html#SCS Signed-off-by: Roman Penyaev <r.peniaev@gmail.com> Cc: "Marc-André Lureau" <marcandre.lureau@redhat.com> Cc: qemu-devel@nongnu.org Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-ID: <20250226075913.353676-2-r.peniaev@gmail.com>
