Author: jhb Date: Thu May 9 20:30:35 2019 New Revision: 347406 URL: https://svnweb.freebsd.org/changeset/base/347406 Log: MFC 333235: Allow arbitrary numbers of columns for VNC server screen resolution. The prior code only allowed multiples of 32 for the numbers of columns. Remove this restriction to allow a forthcoming UEFI firmware update to allow arbitrary x,y resolutions. (the code for handling rows already supported non mult-32 values) Modified: stable/11/usr.sbin/bhyve/rfb.c Directory Properties: stable/11/ (props changed) Modified: stable/11/usr.sbin/bhyve/rfb.c ============================================================================== --- stable/11/usr.sbin/bhyve/rfb.c Thu May 9 19:03:52 2019 (r347405) +++ stable/11/usr.sbin/bhyve/rfb.c Thu May 9 20:30:35 2019 (r347406) @@ -544,40 +544,23 @@ rfb_send_screen(struct rfb_softc *rc, int cfd, int all } for (x = 0; x < xcells; x++) { + if (x == (xcells - 1) && rem_x > 0) + cellwidth = rem_x; + else + cellwidth = PIX_PER_CELL; + if (rc->hw_crc) crc_p[x] = fast_crc32(p, - PIX_PER_CELL * sizeof(uint32_t), + cellwidth * sizeof(uint32_t), crc_p[x]); else crc_p[x] = (uint32_t)crc32(crc_p[x], (Bytef *)p, - PIX_PER_CELL * sizeof(uint32_t)); + cellwidth * sizeof(uint32_t)); - p += PIX_PER_CELL; + p += cellwidth; /* check for crc delta if last row in cell */ - if ((y & PIXCELL_MASK) == PIXCELL_MASK || y == (h-1)) { - if (orig_crc[x] != crc_p[x]) { - orig_crc[x] = crc_p[x]; - crc_p[x] = 1; - changes++; - } else { - crc_p[x] = 0; - } - } - } - - if (rem_x) { - if (rc->hw_crc) - crc_p[x] = fast_crc32(p, - rem_x * sizeof(uint32_t), - crc_p[x]); - else - crc_p[x] = (uint32_t)crc32(crc_p[x], - (Bytef *)p, - rem_x * sizeof(uint32_t)); - p += rem_x; - if ((y & PIXCELL_MASK) == PIXCELL_MASK || y == (h-1)) { if (orig_crc[x] != crc_p[x]) { orig_crc[x] = crc_p[x];
