From 4c81ff45668ba682eb5d3a9f7080d8b14218c040 Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Thu, 12 Jul 2012 11:31:42 +0000 Subject: [PATCH] Redo the RandR code in Xvnc/libvnc to use the modern 1.2 API. The old stuff was a bit buggy, and it didn't really allow us to move forward. This commit temporarily removes the ability for the client to resize the session. It will be readded for Xvnc in a later commit. libvnc will be without that functionality for now, as it is very difficult to get right there. git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@4931 3789f03b-4d11-0410-bbf8-ca57d06f2519 --- unix/xserver/hw/vnc/XserverDesktop.cc | 158 ++++++++---------- unix/xserver/hw/vnc/XserverDesktop.h | 14 +- unix/xserver/hw/vnc/vncHooks.cc | 121 +++++++++++--- unix/xserver/hw/vnc/xf86vncModule.cc | 9 + unix/xserver/hw/vnc/xvnc.cc | 229 ++++++++++++++++++++------ 5 files changed, 366 insertions(+), 165 deletions(-) diff --git a/unix/xserver/hw/vnc/XserverDesktop.cc b/unix/xserver/hw/vnc/XserverDesktop.cc index 5fc32c3a..6b1c2d9d 100644 --- a/unix/xserver/hw/vnc/XserverDesktop.cc +++ b/unix/xserver/hw/vnc/XserverDesktop.cc @@ -200,6 +200,8 @@ void XserverDesktop::unblockUpdates() void XserverDesktop::setFramebuffer(int w, int h, void* fbptr, int stride) { + ScreenSet layout; + width_ = w; height_ = h; @@ -217,7 +219,66 @@ void XserverDesktop::setFramebuffer(int w, int h, void* fbptr, int stride) data = (rdr::U8*)fbptr; stride_ = stride; - server->setPixelBuffer(this); + layout = computeScreenLayout(); + + server->setPixelBuffer(this, layout); +} + +void XserverDesktop::refreshScreenLayout() +{ + server->setScreenLayout(computeScreenLayout()); +} + +ScreenSet XserverDesktop::computeScreenLayout() +{ + ScreenSet layout; + +#ifndef RANDR + layout.add_screen(Screen(0, 0, 0, pScreen->width, pScreen->height, 0)); +#else + rrScrPrivPtr rp = rrGetScrPriv(pScreen); + CrtcIdMap newIdMap; + + for (int i = 0;i < rp->numCrtcs;i++) { + RRCrtcPtr crtc; + + crtc = rp->crtcs[i]; + + /* Disabled? */ + if (crtc->mode == NULL) + continue; + + /* Known CRTC? */ + if (crtcIdMap.count(crtc) == 1) + newIdMap[crtc] = crtcIdMap[crtc]; + else { + rdr::U32 id; + CrtcIdMap::const_iterator iter; + + while (true) { + id = rand(); + for (iter = crtcIdMap.begin();iter != crtcIdMap.end();++iter) { + if (iter->second == id) + break; + } + if (iter == crtcIdMap.end()) + break; + } + + newIdMap[crtc] = id; + } + + layout.add_screen(Screen(newIdMap[crtc], crtc->x, crtc->y, + crtc->mode->mode.width, + crtc->mode->mode.height, + 0)); + } + + /* Only keep the entries that are currently active */ + crtcIdMap = newIdMap; +#endif + + return layout; } char* XserverDesktop::substitute(const char* varName) @@ -727,100 +788,15 @@ void XserverDesktop::clientCutText(const char* str, int len) vncClientCutText(str, len); } -#ifdef RANDR +extern unsigned int vncSetScreenLayout(ScreenPtr pScreen, + int fb_width, int fb_height, + const rfb::ScreenSet& layout); + unsigned int XserverDesktop::setScreenLayout(int fb_width, int fb_height, const rfb::ScreenSet& layout) { - int i; - Bool ret; - RRScreenSizePtr pSize; - RROutputPtr output; - RRModePtr mode; - - // Make sure all RandR tables are properly populated -#if XORG == 15 - ret = RRGetInfo(pScreen); -#else - ret = RRGetInfo(pScreen, FALSE); -#endif - if (!ret) - return resultNoResources; - - // Register a new size, or get a reference to the existing one - pSize = RRRegisterSize(pScreen, fb_width, fb_height, - pScreen->mmWidth, pScreen->mmHeight); - if (!pSize) { - vlog.error("setScreenLayout: Could not get register new resolution"); - return resultNoResources; - } - ret = RRRegisterRate(pScreen, pSize, 60); - if (!ret) { - vlog.error("setScreenLayout: Could not register a rate for the resolution"); - return resultNoResources; - } - - // Then we have to call RRGetInfo again for it to copy the RandR - // 1.0 information to the 1.2 structures. -#if XORG == 15 - ret = RRGetInfo(pScreen); -#else - ret = RRGetInfo(pScreen, FALSE); -#endif - if (!ret) - return resultNoResources; - - // Go via RandR to set the resolution in order for X11 notifications - // to be sent out properly.
