From f9344933bcc1425cf1e8142dc2f8321522dc00af Mon Sep 17 00:00:00 2001 From: Alon Levy Date: Fri, 24 Feb 2012 23:19:29 +0200 Subject: [PATCH 416/434] qxl: remove flipped Tested on linux and windows guests. For negative stride, qxl_flip copies directly to vga->ds->surface->data, for positive it's reallocated to share qxl->guest_primary.data Signed-off-by: Alon Levy Signed-off-by: Gerd Hoffmann --- hw/qxl-render.c | 66 +++++++++++++++++++++++++------------------------------ hw/qxl.h | 2 +- 2 files changed, 31 insertions(+), 37 deletions(-) diff --git a/hw/qxl-render.c b/hw/qxl-render.c index a7891b2..5811d74 100644 --- a/hw/qxl-render.c +++ b/hw/qxl-render.c @@ -23,10 +23,21 @@ static void qxl_flip(PCIQXLDevice *qxl, QXLRect *rect) { - uint8_t *src = qxl->guest_primary.data; - uint8_t *dst = qxl->guest_primary.flipped; + uint8_t *src; + uint8_t *dst = qxl->vga.ds->surface->data; int len, i; + if (qxl->guest_primary.qxl_stride > 0) { + return; + } + if (!qxl->guest_primary.data) { + dprint(qxl, 1, "%s: initializing guest_primary.data\n", __func__); + qxl->guest_primary.data = memory_region_get_ram_ptr(&qxl->vga.vram); + } + dprint(qxl, 1, "%s: stride %d, [%d, %d, %d, %d]\n", __func__, + qxl->guest_primary.qxl_stride, + rect->left, rect->right, rect->top, rect->bottom); + src = qxl->guest_primary.data; src += (qxl->guest_primary.surface.height - rect->top - 1) * qxl->guest_primary.abs_stride; dst += rect->top * qxl->guest_primary.abs_stride; @@ -75,52 +86,38 @@ void qxl_render_update(PCIQXLDevice *qxl) { VGACommonState *vga = &qxl->vga; QXLRect dirty[32], update; - void *ptr; int i, redraw = 0; - - if (!is_buffer_shared(vga->ds->surface)) { - dprint(qxl, 1, "%s: restoring shared displaysurface\n", __func__); - qxl->guest_primary.resized++; - qxl->guest_primary.commands++; - redraw = 1; - } + DisplaySurface *surface = vga->ds->surface; if (qxl->guest_primary.resized) { qxl->guest_primary.resized = 0; - if (qxl->guest_primary.flipped) { - g_free(qxl->guest_primary.flipped); - qxl->guest_primary.flipped = NULL; - } - qemu_free_displaysurface(vga->ds); - qxl->guest_primary.data = memory_region_get_ram_ptr(&qxl->vga.vram); - if (qxl->guest_primary.qxl_stride < 0) { - /* spice surface is upside down -> need extra buffer to flip */ - qxl->guest_primary.flipped = - g_malloc(qxl->guest_primary.surface.width * - qxl->guest_primary.abs_stride); - ptr = qxl->guest_primary.flipped; - } else { - ptr = qxl->guest_primary.data; - } - dprint(qxl, 1, "%s: %dx%d, stride %d, bpp %d, depth %d, flip %s\n", + dprint(qxl, 1, "%s: %dx%d, stride %d, bpp %d, depth %d\n", __FUNCTION__, qxl->guest_primary.surface.width, qxl->guest_primary.surface.height, qxl->guest_primary.qxl_stride, qxl->guest_primary.bytes_pp, - qxl->guest_primary.bits_pp, - qxl->guest_primary.flipped ?
