From e1ec62c46a0be4c40414df02f9b6fccfca94006e Mon Sep 17 00:00:00 2001 From: Luke Shumaker Date: Mon, 28 May 2018 21:18:43 -0400 Subject: Update libre/qemu-user-static and dependencies Fighting with glib2 was no fun. But hey, at least I got a GCC bug report out of it! https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85957 To get around this, I enabled SSE2 for glib2-static. This means it won't run on pre-Pentium 4 (2001) i686 processors; which will cause problems on the Pentium Pro/2 and the Pentium 3, and their AMD competitors: K6 and K7 (the latter of which was branded as Athlon, Athlon XP, Duron, and Sempron). https://lists.parabola.nu/pipermail/dev/2018-May/006748.html If someone digs out a Pentium 2 and gets Parabola to boot on it, I'll figure out a different way to get around glib2's disagreement with x87 floating point math; and turn SSE2 back off. --- ...init_guest_commpage-Add-a-comment-about-s.patch | 30 ---------------------- 1 file changed, 30 deletions(-) delete mode 100644 libre/qemu-user-static/0006-linux-user-init_guest_commpage-Add-a-comment-about-s.patch (limited to 'libre/qemu-user-static/0006-linux-user-init_guest_commpage-Add-a-comment-about-s.patch') diff --git a/libre/qemu-user-static/0006-linux-user-init_guest_commpage-Add-a-comment-about-s.patch b/libre/qemu-user-static/0006-linux-user-init_guest_commpage-Add-a-comment-about-s.patch deleted file mode 100644 index 4436b7817..000000000 --- a/libre/qemu-user-static/0006-linux-user-init_guest_commpage-Add-a-comment-about-s.patch +++ /dev/null @@ -1,30 +0,0 @@ -From ca873a81cc020df0ee0ec072a60678bb83dce9e2 Mon Sep 17 00:00:00 2001 -From: Luke Shumaker -Date: Wed, 27 Dec 2017 21:05:29 -0500 -Subject: [PATCH 06/10] linux-user: init_guest_commpage: Add a comment about - size check - -Signed-off-by: Luke Shumaker ---- - linux-user/elfload.c | 5 +++++ - 1 file changed, 5 insertions(+) - -diff --git a/linux-user/elfload.c b/linux-user/elfload.c -index 22f2632dfa..b560f5d6fe 100644 ---- a/linux-user/elfload.c -+++ b/linux-user/elfload.c -@@ -374,6 +374,11 @@ static int init_guest_commpage(unsigned long guest_base, - - /* If the commpage lies within the already allocated guest space, - * then there is no way we can allocate it. -+ * -+ * You may be thinking that that this check is redundant because -+ * we already validated the guest size against MAX_RESERVED_VA; -+ * but if qemu_host_page_mask is unusually large, then -+ * test_page_addr may be lower. - */ - if (test_page_addr >= guest_base - && test_page_addr < (guest_base + guest_size)) { --- -2.15.1 - -- cgit v1.2.3
